Is it shaking or does it seem like it's hesitating?

My car also has a slight vibration under medium/heavy acceleration. So BUMP. anybody know? Mine started right after i put my new struts/springs on. Need alignment bad.

steveo

did you lower the car

Could be time to replace the wheel bearings(new hubs), intermediate shaft bearing, maybe add some rack spacers while your at it (if lowered).

Im in line to do so soon...my front suspension is all out of whack right now.

it seems to me its shaking and not hesitating. also it doesn't seem to be constant somtimes worse than others.

rallyracer

depending on how many miles and what not I think it may be time to replace some parts...

PANIK

mine does the opposite but i know my front brakes are doing it

your problem is called wheel hop

jk

i would say if it is lowered maybe spacers

front end alignment maybe?

not really sure

its an axle...

I just had the same problem. If it follows the RPMs more so than the road, its more than likely an axle.

I just changed my axles, no help. Next step is an alignment.

I have the same problem seems under hard acceleration mostly . Iwill start with the cheapest part to replace ofcoarse LOL. I dont thin kits an axle bothe were changed so most likely gona be control arm bushings or some crap in the suspension and yes mine is lowered aswell i guess lowering it is puttin more stress on the busings .

Im getting an alignment done prolly this week. Ill post up if this fixes it.
