I got a problem here, I have just installed the mods in my sig and under wot the whole car shimmy/shakes any ideas of what might be causing this? all help appreciated.

 

sub'd

 

axles, or the Cv joints more specifically. mine did the same thing.

 

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.

 

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.

 

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

 

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

 

Yea its from right after me putting the h&rs on.

 

I just drove it again an tried a few things and it seems that the wiggle is very noticable in the gas pedal...? Now i am thoroughly confused any ideas?

 

mine was the axles and lower control arm bushings ... sucks becouse gm is the only one with ower stock axles i put after market bushing and fix mine right up

 

This is most likely your problem.

 

Tire rods.. my car dose a shimmy shake type deal when i get on it then cruising it goes away my buddy checked it out and he said its my tire rods. check if theres any play in the wheels?

 

u need the steering rack spacer. mine does the same thing on the h and r

 

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.
