major diff problem!

[S2on20]

i know its been done before, but i need some advice on what to do...

ive never had an issue with the diff, even last week diff was fine, then last thursday a slight whine. noticeable in neutral but heaps louder under throttle. fri, sat, sun got worse, so monday i changed the diff oil and even put in an additive that the bloke at repco recommended to quiet it down.
It didnt change a thing, come tuesday a little louder and can even hear the teeth grinding agaised each other in speeds below 20k's, and today (wed) the whine has got so loud its actualy louder then the engine, and im am actually scared of it breaking and locking up while im driveing.

so question is sld i just drive it till it breaks, and get a new (second hand one) or take this one to a diff joint for em to check it out?

ive read a few guys here have had similar problems... did u get your old one rebuilt or got another one from wreckers?? if so where and any prices?? thanx.

[Si1enzio]

I would of stopped driving when you first noticed it lol...
Time for a rebuild, take it to a diff place & get it inspected.

[DvS-]

just get in inspected.. and just rebuild it if need be..

[S2on20]

yeah thats the probably the right thing to do, but im in between changeing jobs and short on $$$ atm. has anyone had there diff rebult? any ideas on price?

[YLDS2K]

i got quoted $2200 for a rebuild and that comes with a little civic courtasy car with a etag if need be. I havent done mine yet as mine has just started whinding and they were the cheapest and best i found. Im sure there are possibly places i dont know about but from who i called i felt they knew what they were on about. Apparently his son has a S2000, i dunno if this is a positive or a negative, as they might know what they are doing, yet, what ifhe decided to play with certain parts that he doesnt need 2 be.

Im not saying they are known for this, but it has happened in the mechanical industry, so dont blast me if you guys think i am mud slinging at hondworld.

[euromandeluxe]

while you're at it, change the final drive! 4.44 ftw!

Hey mate,

I just got mine rebuilt 2 weeks ago. They had to change two parts that could only be found from Honda, costing 1500 all up. The labour to uninstall, reinstall and have a diff specialist rebuild it added 1250 on top. And guess what? Im taking it in again for the same problem tomorrow!

My advice - get a whole knew diff.

[STAiN MASTER]

good chance it could be your CV's rather then your diff id get it checked out immediately!

if your in sydney go to hannys, speak to robert or pip.

[S2on20]

s2kjn... u payed $2750 for part and labour and still no good? whats wrong with it? do u have same syptoms as mine?

STAiN MASTER... its lowered on 20's, i broke 1 CV so repleced both of them bout 2000k's ago.

im in melb so any 1 dealt with diff places here?

[YLDS2K]

s2on20 was your car advertised on the trading post a while back and was located at a place where the guy sells those pearl coloured lancers with body kits on the hume hwy not sure of the dealerships name

[S2on20]

na mate i picked it up dec last year from sydney... it was a fun drive home lol

[JS2k]

Mate get your diff checked out before buying another one, you dont even know whats the problem yet

Sounds like the diff though, its rare for a driveshaft to make a whining noise

My experience is diff rebuilders will never get i right even though they should

[s2kjn]

s2on20,

Had to change the crown & pinion which cost the 1500 from Honda. The pinion itself had a massive chunk torn out of it which caused the loud "whine & teeth grinding" noise which you hear.

My problem now is that its just making a clunking noise as I launch from neutral to first and even changing between gears, as well as swinging the clutch in and out, I hear a clicking noise coming from the diff. The car is still at the mechanics, I will let you know what happens.

Cheers

im having the problem ur currently having. today i went to 4 diff/performance joints in melbourne and 3 out of them 4 said to me "goodluck' and that is it.
this 1 guy in thomastown, 'auto trans n differentials'? i think, took my car for a drive and said straight away that one of my axels are gone. once we took it up on the hoyst, i touched the left axel where the rubber boot is and there was grease leaking out..
then he told me that unless i raise my car, which is sitting on its ass on the rear, he will not touch my car or even open up the diff. ive got driveshaft spacers n he said to me that they r the only thing that has stopped my axels from snapping at this point. Mind u i have already replaced both rears just 9 months ago. apparently the angle of the shafts munch everything due to the s2k being lowered..which im sure most of u all no.
2morrow i raise my car back on2 stock suspension and then i guess the car will be going in for a check up and possibly a diff rebuild.
at this point i have no clue really how much its gonna cost but the guy said 2 me that he woudlnt be suprised if most of the noise im getting in the rear will disappear once i change the heigth back 2 stock settings.
i will post up exact prices of what is needed 2 changed just incase everyone else is in the same boat.
would also like some input on what you guys think or have herd price wise.
im also waiting on a qoute for a brand new diff from honda which i should find out 2morrow morning.
Apparently my mate knows someone whos the head manager of wirraway honda in essendon and can get me the diff for half price.
anyone no wat they go for brand new?

[JS2k]

Haha, make sure you're seated when you get the new price on the diff from Honda

You wont get much change out of $6000 - $7000

Get the car back to standard height before proceeding any further with repairs

[tamay_s2k]

just spoke 2 honda and they told me brand new differential is $5945
now im on the phone waiting for my mate who can hopefully do me a better price
*10minutes later*
$4000 just for the internals

[s2kjn]

The mechanic is changing the drive shafts now, hopefully this will sort things out. Will hoefully get the car back today, will let u kno

Axle Pops or Creaks:


’00–02 S2000

On 00-02 S2000s, if your customer complains of
hearing a single pop or creak from the rear of the
vehicle when changing direction from forward to
backward and vice versa, the problem may be
axle (driveshaft) movement in the rear hub. To
eliminate the noise, replace the spindle nut on the
affected axle. Apply grease to the surface of the
new spindle nut where it contacts the hub. Torque
the new nut to 298 N-m (220 lb-ft), and stake the nut.

[S2on20]

tamay_s2k how did u go? any prices from the place in thomastown?


s2kjn i think your spot on about it being the crown and pinion... the whineing teeth grinding noise says it all. did u try getting a second-hand one or go strait to honda for a new one? who fitted it and how much?

with the price of $5949 for a new diff i think that will be my last resort...
still driveing my sisters yaris around lol

[s2kjn]

Bought brand new from Honda, material cost $1,500. Add $600 for it to get rebuilt. Finally got my babi back last night. I had the diff rebuilt and the driveshafts changed, but still have a thudding noise when going into first from idle. Mechanic reckons its time for a gearbox rebuild soonish.

[vyets]

tud noise into first is normal.

[s2kjn]

Have you got the same noise vyets? where would you say its coming from?

[vyets]

happens with most cars just the way the tranny engages gears.

[s2kjn]

Hmm.... very interesting read. Seems to be a mix of ideas from s2ki. But i agree with alot who posted that if you roll up in gear, then neutral at a stop, then first, there is no thud. Thanks vyets!

Your mechanic must be very happy every time he sees you. The thud is normal and happens because the main shaft on the transmission is spinning with the engine, so when you push the clutch in the transmission has to stop when you engage first.

You coulda saved a packet and done this...http://www.ozhonda.com/forum/showthread.php?42876-Final-gear-for-s2000

[s2kjn]

Haha nah dont think so.

To start with bout 4 weeks ago, the diff blew, and the pinion had a massive chunk missing from it (saw it myself). Couldn't move the car anywhere, so then bought the crown & pinion from honda and got a rebuild. Only after i had it rebuilt, i noticed that the thud noise was coming into play, but its possible that because ive paid a wealthy sum, i guess im but paranoid. Drive shafts had to be changed badly as well.

[jbird]

The diff didn't blow if they didn't change the centre?

It sounds like the CW/Pinion broke...in which case you could've just got a mazda/kia cw/pinion for less.

Your driveshafts being changed sounds like overkill. the CV Cups coulda just been swapped from left to right or driveshaft spacers put in...

[jeremy_74]

Which other crown/pinions are interchangable with the S2000's?

[s2kjn]

Sorry that's what i meant to say. Yes the crown & pinion did brake

[ludecrs]

Which other crown/pinions are interchangable with the S2000's?

Kia..

Hi Guys,

I`ve been searching and reading other people's blogs but not 100% sure if anyone has the exact same problem as me. I`ve got a 99 s2k and I`ve recently started to hear teeth grinding noises in my rear left. The noise is constant and occurs even when I`m driving straight and not turning or braking. The noise amplifies at about 40kms onwards.

Initially, i thought it was the wheel bearings, bald tyres, or brakes scrapping (really sounds like this) but after peds suspensions looked at it and put it on a hoist running, they pointed out that the noise was coming from the diff. The prev owner changed the diff oil recently with Motul and I`m thinking could it be the different oil thats making the noise? The diff doesn't make the knocking noise but just the teeth grinding noise. Also the diff was serviced at the start of the yr and bearings changed by the prev owner's mechanic.

I would really appreciate any help here pls!
