rear vibrations

[lzybum]

hey guys

i've been having some rear vibrations while driving for the past few days.
it only happens when i accel over 4k rpm, so normal grannie driving still feels normal.

i've been reading through s2ki about this problem and they say its the CV joints and problems that causes them is because the car has been lowered or ride height is changed.

i have no changed the height of the rears yet (still the same height as how i bought it ages ago), just only lowered the fronts a month ago.

so i was just wondering...if i've shaved off 15-20kgs from the rear (installed exhaust)....would this possibly cause the CV joints to move away from its normal wear-spots?

if the CV joints are the problem...would driveshaft spacers do the trick?

cheers guys.

This is not true that only lowered s2000's get this vibration, they all eventually get it. Lowering will only cause it sooner. Shaving any weight off will not achieve anything. As the main cause is due to a poor design with the inner joint.
Yes buying spacers will help for quite some time providing the vibration is bad. If it is bad, swap the LHS inner joint with the RHS inner joint and your vibration problem will be solved.

wat i meant was...right after i installed my exhaust, coincidently i get the vibrations...so thats why im asking...could the shaving off the weight from the rear contributed to the problem?
if not...then it probably is the case..like u said...was bound to happen sooner or later lol

Ive bought spacers about 5 months after I installed my suspension (should have done it at the same time). Ive recently swaped my cv's. The virbration has gone but even with the sapcers i still get clicking at low speed turns no matter how much i tighten the axel nuts.

Like JAP-S2K said, its gonna happen, swap em around and see how you go.

Have a look at your exhaust... there might be a point where its vibrating on the body. Just seem strange how it occured right after installing it. Or even take it off and test it out to see if thats causing it.

The clicking sound is normally your outer hubs, they make a clicking sound, due to the fact they could do with some grease. However this doesn't always get rid of the clicking sound. It's more a slight amount of play in the outer hub. Nothing really worth worrying about.:thumbsup:

Yeah im kinda familiar with the issue. As i said i had my cv's swaped recently (bout a month ago)the outer hubs and axel ends were both greased. Just another of the cars little quirks. Im not too fussed with it

I had the same problem. Just change your inner cvs around. i.e. left to right and right to left.

[lzybum]

will do guys !
cheers for the info!

************* IMPORTANT ***************

i HAD the same problem and now its gone due to one simple easy priceless adjustment....

check your tyre pressures.

my vibriation was under accel too just like yours and now its gone for now lol i pumped my tyres to 38psi they were all on 28.

i dont know how or why it fixed the vibration but it has. for how long i dont know but im loving it :D

The only way this is possibly is if left and right rear tyres are at different pressures, eg L20psi R35psi. but the rear of the car would wander left to right when accel and decel. Increasing tyre pressures alone shouldn't change anything though.

i know man thats what i thort but it has changed it heaps its actually now starting to come back but i swear its no were near as bad as it was :S:S:S:S:S

[JAP-S2K]

Have you fitted spacers yet? if not, nows the time. Otherwise if it gets bad, spacers won't do anything.

[lzybum]

no i havent fitted spacers yet
im planning on getting it checked out first this coming friday
let the pro mechanics see if anythings out of place, if nothing then will get them to switch the cv's.

switching the cv's are better/longer lasting thing to do than just adding spacers?

[JAP-S2K]

Yes switching them is far better than installing spacers. But i was actually asking AGE if he had installed spacers yet. Fitting spacers will buy you more time though before needing to swap them.

[Age_S2000]

na man havnt yet i think i will swap them. im doin my clutch next week so while its up ill swap them around.
can u just swap the whole shaft from left to right instead of just the inner cvs....

[JAP-S2K]

No, just swap the inners. You don't need to pull shafts out to do it. It is messy though, be sure to clean all parts up, and regrease them.

[eriktufa]

You can't swap the whole shaft as the length is different.

[lzybum]

got the inner cv joints swapped on friday
and now drives like a beaut!! :D

Good to hear.:thumbsup:

[mr_vtec]

my car had some vibration start yesterday so this morning i started to rip out my cvs and got stuck with one last nut it wont ****ing break loose so yea ill sleep on it and tomoz night ill have a crack at it..

i will be swapping outers over and putting my spacers in..

ill let you guys know how it goes..

You don't need to take the driveshaft nut off. Just keep the nuts in there and you have just enough room to pull the inners out of the diff. ALWAYS undo the ABS sensor as the arms you need to pull off or undo to get the hub to move around to get clearance will stretch the ABS wheel speed sensor wires and cause them to brake inside. Spacers help which moves the wearing to a different part of the inboard joint but only prolongs it. Next step is to swap them either side. A full rectification is to repace the inboard joints with a billet item which gets rid of the crap inner joint trapazoid style with ball and cage. But your looking at around $800 a side but you will never break them with a stansard diff centre.

The clicking is simply, like Steve said, is the driveshaft splines in the hubs being dry. Undo the nut and a couple of arms and you can still clean away the rust and regrease them then do them back up. A good trick is to swap the nuts either side so when you knock the rim in to lock it off, it should be in a different spot.
