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

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]

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?
