steering wheel shake/vibrate under heavy acceleration

[anzai]

hey guys my dc2r shakes under heavy acceleration on third and fourth gear

wheel alignment didnt fix the issue

tried adjusting coilover damper to no avail

checked tyre pressure they are all good

im thinking it could be driveshaft or engine mount related, havent had time to go under the car, but just wondering if anyone could suggest what may have caused it

thanks heaps

running hub centric rim things?
whens last time the brakes were skimmed?
is it just under acceleration or is it at speed in those gears?

[lolmclol]

If its engine mounts ... you should be getting feedback whilst changing gears even at lower speeds ...

Could be wrong though.


Or you could be hitting that vtak too hard ;D .. lol jokes.

you may need to pack more grease into the inner CV joints

[anzai]

Im running rpf1s not sure if they are hubcentric or not... engine mount was filled with es poly fillings about a year ago. Ill check the cv joints, upper ball joint is good since i upgraded to hard race uca, tie rods not sure...

maybe gearbox? does it ever pop out?

[anzai]

Nah gb is ok, never pops out

[GU357]

hmm well then why would it only happen in 3rd and 4th? but no other gears?

[Evok]

Engine mounts.

machine brakes and new pads?

Have you tried a different set of wheels with decent tread on tyres

Most of the time it has to do with the tires

Check of tyres are worn evenly

So it doesn't do it in 2nd or 5th? At all?

You sure the wheels are balanced properly? Maybe some have fallen off, or your tyres have worn to the point where the weights are no longer accurate?

^this would be most likely cause.. or gearbox issue.

check the torque mounts

[SimonF]

You would only notice torque mounts through linkage. I didn't run any torque mounts on my B16A throughout the whole time i had it, just made gear changes a bit sloppy at higher rev's as engine was swinging. If anything, that would cause less vibration as less of the engine is touching the car. Same as if he had the opposite and had Hasport mounts with the harder rubber, it would shake like hell ha.

Rotors are gone? I had the same problem in my em1. one of the engine mounts were showing signs of wear (front support) i replaced Didn't fix...went on re balancing, new tyres, re machining the old rotors, new bendix pads even went to 6 different mechanics.

It was the rotor's, changed the front 2 and no problem at all. Try it cant hurt.

K i read the tread, it was a similar problem. The car would rattle shake like fudge effects heavily felt from the steering wheel when trashed or breaking from a high speed..coming off the m5.
