Vibration noted at track day

[troys2000]

Hi,
Recently did a track day at eastern creek with driving solutions I high recommend it was awesome! And was the only Honda! Someone come with me next time! The instructor advised me of a vibration in the rear and he thinks it drive train of some kind, possible diff and only when acceleration. I have inspected under neath nothing obvious. Anyone had a similar problem or any ideas?

[vyets]

Nice too see another S2000 hit the tracks! Good stuff mate.
Vibrations could be anything from a wheel aligment to a wheel bearing or a loose nut!!! :O
It's hard to say but how bad is the vibration is it on low and high speed or just as soon as you punch the accelerator?

[troys2000]

Thanks,
I am going to get a wheel alignment soon. It’s not a loose nut. Its not major major and yes only when I am going a bit hard but the instructor said it’s something you want to find. I will try and get it checked out but I feel its going to be one of those things where to start looking and how to test for it.

[xntrik]

mostlikely wheel alignment, from dumpage.

[MRK-01]

mine is also showing a vibration. seeing its still under warranty, getting honda to check it out this week. Hope its not the diff, cause I only feel it under hard acceleration.

if it is the diff, i hope this is covered under warranty..!!

[ludecrs]

If your diff is rooted, sell it to me realllly cheap under replacement warranty LOL.

[NVD52K]

i think its your bearing wearing out, go and get it swapped opposite right to left vise versa so it wears out evenly happens when you dump the car from camber

[vyets]

Do you have aftermarket rims? Maybe you need a Hub Centric ring, or if slammed it could be your shafts as well lol too many shit :(
I had vibration while ago but it went away

[troys2000]

Hum,
MRK-01 Keep us updated. I have stock black rims but it does have lowered spoon springs. I might start with the wheel alignment and get under the car and have another good look.

[CONAN]

I had the same problem, vibrations under acceleration, if you lift off the throttle it goes away. does not happen during braking, deceleration or slowing down. Friend also had the same problem in his S2000. Started occurring after a track day, guess it was due to the heavy load during track sessions.

Is your car lowered? Or has it been lowered in the past? The fix was to swap around the rear Inner CV's. Once this is done your problem should be fixed. It is a common problem on lowered S2000s.

Should take about an hour, and about $150.

Let us know how you go.

[MRK-01]

Your explanation is perfect..!! When on full load, usually in VTEC range it shakes its ass off..!! Didnt go down well with a prospective buyer..!!

I have been very careful with this beast, so I would not think the rim's are in any way buckled. If they are, I have a second OEM set I will test out(one set black other Grey).

I have booked it into Honda tomorrow, so hopefully they wont charge through the nose.....Had to take all the gear off it..!! Whiteline Engine lower engine brace, front stut support, Exhaust, CAI....Even took out the heavy duty sway bars. The only thing I didnt change were the springs. I bet the warranty is null and void..:thumbdwn::thumbdwn:

The extended Honda warranty I hope will cover this, but if no luck I will have to fork out$$$$ 150 isnt a prob, will wait on what Honda say.

It has HR springs now, the ride hieght is down about an inch, so I would think it has something to do with the CV's from what you all describe. I have an original clutch so I would not think that could affect the diff in such a way.

Will advise soon.

[CONAN]

When on full load, usually in VTEC range it shakes its ass off..!!

Yep the car starts vibration and shaking, and it gets worse and worse. It was actually a puzzling problem as well! I originally thought it could be
- Diff
- Brakes
- Wheel Alignment
- Buckled wheels
- Gearbox

Lucky after much research I decided to swap the inner cvs around and it was $150 well spent. Felt like new again, once fixed.

[aznsiko]

its your drive shafts.. i cant say 100% sure but its a common problem that alot of us have had in the past... just do the CV swap from left to right.. there is a DIY write up on s2ki..

[MRK-01]

will let honda do it, i not too comfy doing CV's anyway...bloody messy......hope they dont charge through the ass tho..!!

[MRK-01]

Honda just called. they said the CV /Driveshafts are rooted. Need to be replaced....Scary bit is $1700 to replace them..!! And the warranty is null and void because I didnt service the car with them every 6months/10000km's...!!! I didnt service it that often cause I dont drive ti that often..!!!
So, anyone know where I can get my handa on a new set of drive shafts..? For less than $1700..????

[NVD52K]

dont replace them swap them left to right man and save yourself money !!

[MRK-01]

I will check on this over the weekend, are the left and right identical..??

[troys2000]

Bugger! I hope this is not what’s wrong with mine! I think I will stay with the wheel alignment 1st and see how I go. Swap them around seems interesting but is that only a temporary fix? This is starting to worry me greatly! If anyone can remember not long after the purchase of my s2k I had to replace the engine!
Maybe you should consider wreckers one with low Km’s or parts importer.

Happy BDay to me! lol

[MRK-01]

It would be cheaper to have the CV/Driveshafts (dont know the exact name of them) serviced by a Driveshaft specialist. It couldnt be that expensive to change the CV joints and re pack them in grease....!!

[NVD52K]

what happens is your cvs wear out un evenly because of your camber . and all you have to do is swap it left to right vise versa they do sit properly and the noise will go away and after swapping it they will wear out evenly again


guys dont be worried its not a big thing just get them swapped!

[MRK-01]

Possible to do in the home garage..? Or is it easier to be done at a shop..?

[MRK-01]

just spoke to my mechanic (not honda dealer), he could get the driveshafts serviced and replaced easily, but not too keen on swapping them from left to right.....
How confident are you that this works..? Is it a known fix..?

[ludecrs]

Its a cheap fix most owners do when the time comes.

[CONAN]

Highly recommend you do it on a hoist!!

[MRK-01]

Sweet, mechanic has a hoist free..!! Honda can go jam their 1700 quote..!!

I will advise once done. thanks for the info..!!

[MRK-01]

I found the left and right drive shafts are diffrent length's. So I have had them reco'd. This should help. Damn sight less money than buying new ones...!! Should get it back tomorrow......

[JAP-S2K]

J's racing driveshaft spacers also do the trick once your've swapped the inner cv's around. As the spacers make it wear on a less used section. Unfortunately the inners are a poor design and are prone to wearing out and breaking. I'm sure i'm not the only one that's broken plenty of inners.

[MRK-01]

The driveshafts got reco'd and are now perfect..!! Less than half the cost then getting Honda to do it..!!

So if you have the prob get it seen to by a driveshaft specialist and simply get them reco'd..!! ALL done..!! less than 800 bucks it cost to have them done, labour and all..!!

You could do it at home, but you need a ball joint splitter tool to get access to remove the driveshafts.

Anyways all done, thanks for the info all..!!

[troys2000]

Good out come!
I will do the same with mine if wheel alignment does nothing. Your right my local Honda Dealer is very expensive I usually go to another one 30mins away.
Fixing the A/C in next on this list lol.

[STAiN MASTER]

Great to see you resolved your problem, I had the same problem during acceleration I got alot vibration, I installed some T1R Half driveshaft spacers and solved my problem.

http://www.evasivemotorsports.com/merchant2/merchant.mvc?Screen=PROD&Store_Code=EM&Product_Code=T1R_SS_AP1_RACE

Its a common problem with lowered S2000's

I wouldn't advise swapping over the cv's its a messy job and very time consuming.

The T1R half spacers only take 30min to install both.

[troys2000]

I have finally got mine looked at. There are certain that it’s due to it being lowered and the angles ECT and the shafts not being a square angle from the diff and when you accelerate the car squats and make the angles worse. We are going to look into a wheel alignment and camber to help this. So everything else seems sweet  it just wears tyres more as well lol

[Age_S2000]

OMG OMG OMG finally i have the same problem and i thort that might have been why mines lowerd too and vibrates only under acceleration. i put new tyres and balanced them too and its still there too lol please PM me and tell me how u got after wheel alignment please :D

[CONAN]

swap them inner cv's buddy

[mr_vtec]

i havent got that yet touch wood but i think i might invest in T1R shaft spacers..

is the half one the one i need..

[.::F[L]Y::.]

The shaft spacers only change the wear point on the CV shaft. There was a long ass thread on the effectiveness of the shaft spacers on s2ki.com

You can just get the ebay ones, they all do the same shit. The T1R half style spacer just means you can install them without taking off the whole shaft...

[troys2000]

I am swapping the shafts around on Wednesday!
Then maybe think about the spacers. Are they worth doing after I do this? will they prevent wear?
My car is lowered and done 90,000Kms and I drive hard lol. So I kind think I am doing ok lol

Will someone please give me a positive rating! :-)

[JAP-S2K]

If once you swap the inner hubs round and there's no vibration on accel, then there's no real point fitting spacers, the spacers usually are effective once the inner's begin to vibrate. You should be fine with just swapping them though. Good luck.

[troys2000]

well not good news! one shaft is badly worn and should be replaced, we are still swaping them for now while i try and get new or get them reconditioned! honda charge $1200 each! Help please?

[JAP-S2K]

Theres two sides to every story. Much the same with S2K driveshafts. Honda do sell inner hub and joint for approx $450 each. They'll always tell you that you should replace the whole driveshaft. Which isn't necessary, as the inner joint is the one that wears and eventually breaks. Depending if your mechanically minded, i'd still swap them round myself and see what the outcome is. It's not a difficult job, more a messy one.

[ludecrs]

well not good news! one shaft is badly worn and should be replaced, we are still swaping them for now while i try and get new or get them reconditioned! honda charge $1200 each! Help please?

My mate went to a re-valving / re-conditioning place.

$400 later (he too was quoted 1100-1200 from Honda), he says his car has never driven so good. Fixed all his problems.

[JAP-S2K]

Hey that's a pretty good price.
The only thing with a reco is, they either machine in the inside of the inner hub or replace it. No worries there, and they generally replace the three bearings, no problems there. BUT they don't replace the tri-star which attatches to the splines on the driveshaft. And that's what breaks. So they solve your vibration problem. I'll see if i can post a photo to explain, I've kept a few broken ones.

[troys2000]

Well got it back it seems a little better with them swapped around but its still there. The mechanic advised the inboard joins are very worn, you can get these alone but still approx $400 each with the spider ect. Or get the complete shafts from ebay USA. So sick of spending so much money on my weapon :-( thinking of selling :-(

[ludecrs]

Just an FYI, I looked into prices of complete CV shafts from the US.

Going rate is $80US-$150US for a set, depending on their condition, KM's, and obviously the seller. Many are happy to sell them to you, so check on S2ki.com for an 04-08 parted out AP2 car.

Postage was around the $140US mark by airmail.

[JAP-S2K]

All cars suffer some letdown. bite the bullet, and go custom billet, with ball and cage inners. approx.$1500-$1600 for both and you'll never need worry again about driveshafts.

[Age_S2000]

LUKECRS do you know the name of the place your mate went to im suffering from this problem too...

people post up names of places please :-(

[ludecrs]

Are you in SE QLD?

[troys2000]

JUST POSTED THE BELOW ON NEW THREAD T1R SPACERS

Hey all,
I just got my T1R spacers installed yesterday! IT’S THE BEST! Smooth as now, Got my mechanic to install as they were so dam tight and the driver’s side is harder as the exhaust runs past there. They are in half so makes it heaps easier to install.

I got them for JDM YARD for about $195 including postage these guys rock!

EK4R they are designed to make the CV sit where it should, if your S2K is lowered it moves the spider further out the cup (CV talk) and can cause premature wear, the spacers move it back in to where it is ment to be.

I have been chasing a vibration problem for a while no as per thread “VIBRATION NOTED AT TRACK DAY” swapped cups around worked a little bit but the T1R spacers Rock! I highly recommended this if anyone has a vibration and or is lowered they worked for me.

[troys2000]

Well am now looking for new or used shafts cause the vibration is comming back :-( got the bolts checked and all good.
Know where i can get some? or thinking of doing the swap again

[MRK-01]

I dont have my s2k any more, but I had this fixed up by having the origional shafts reco'd. Cost about 400 but was sure less than getting new or second hand ones.

Due to the shafts not being very common change over is not as easy. So I would take it to the mechanic and have them remove them and give to a drivetrain specialist to reco them.

all tha best..!

[troys2000]

Yea am looking for a drivetrain specialist, asked some CV places and said cant do it :-( its been hard i live in a country town.
Thanks

[STAiN MASTER]

The T1R spacers are good but the nuts and bolt supplied with them are the wrong size they're supplied with 9mm, OEM size is 10mm, due to the size difference any vibration can loosen the bolts, check first to see if the bolts are still extreemly tight.

This happend to me after I installed the T1R spacers after awhile the vibration returned, had a look under the car and my nuts were all loose, replaced them with 10mm bolts and no problems so far.

[troys2000]

Replaced both CVs complete, alot better but still sometimes there. I feel that its the main shaft from the gear box to the diff, going to get it tested, question, can you turn the main shaft around 180 degrees?

[zhong]

Did you check your diff mounts, tranny mounts and motor mounts? These caused minor vibrations on mine before I replaced them.

[troys2000]

Checked diff when installing the new shafts still with the spacers. Getting the main shaft tested Tuesday next week see how that goes, will get him to check other mounts while under there.

[HONTUNE]

Hi, I have a had a couple with vibration under acceleration also worse when release throttle on 3 s2ks was the clutch pressure plate.. Good luck with it.. Hope it's ok..

[ALPS]

Seriously. If you want to track it and have fun with the car. DO what i done. Call up Diff Technics in Sydney. get the 2.9 billet 500hp shafts that they get custom made from America. 1500 including shipping. Best setup. No vibration, very quiet and very smooth plus they handle the power.

[Age_S2000]

Like ^

[troys2000]

Thanks Hontune Hope its not the clutch pressure plate, clutch is maybe 12mths old.
Shafts are new, I am thinking mainshaft now. I see your point ALPS but only plan to do my second track day soon.

[Age_S2000]

Start by putting the drive shaft spacers if u havnt got them its also tge cheapest

[troys2000]

Got the new rear shafts in along with my TR1 spacers, better but still got a shake there, getting the mainshaft from the gearbox to the diff tested today and checking all mounts also.

[s2kjn]

You've had this problem since Dec 08?

[troys2000]

Pretty much, was very bad but first swapped the inner cups around (shafts and different lengths) got better, then shaft spacers, got better again, was good pretty good for a while then the inner cups just got more worn so got new shafts from the USA but now have a minor vibration in some rev ranges and especially under load eg a big hill, thinking its the main shaft now, went to get it tested yesterday but my car was too low for the hoist lol, he is getting the other hoist up and running in a few weeks that will be able to get my car onto it, he has driven it and thinks i am being fussy but i want it right.
