the sound from my car is a thudding noise.. not a clunking noise..... I had the endlinks checked out and they are not the problem in this case.

my thudding noise is definitely coming from the front driver side....... any idea what could be causing it?

When do you get the "thudding" what driving/road conditions at the time?

it's only when I am going up on a driveway in an angle. No sound when I go up straight.

Your going to need it checked out, lower arm or upper arm bushes could be worn, top mount may have gone, the shocker could be worn, swaybar bushes, wheel bearing?

check your a-arm bushing(top and bottom) VERY CAREFULLY.

I just started getting those thudding noises. I thought it was my rack and pinion at first. Like you guys said, it could be the strut. I've been using a lowering spring on a stock shock for a long time now. And when I took out the shock to put the spring on, it was too soft. So Im hoping that could be it.

I have full daizen poly bushes on uppoer lower front and rear. I know these to be good as of last alignment just 4500 miles ago but I'll have it double checked.

what do you mean by top mount?

as for shockers I have TEIN's and the dampener is tested good

sway bushes are also daizen poly bushes front and rear.

wheel bearing... how do I check for this?

thanks

you mean control arm bushings right? I have fully replacement daizen poly bushes. I will double check but I know them to be good as of 4500 miles ago.

It's definitely not the strut for me. I had my TEINs tested and they are still good. Let me know if you swapping struts fixes this problem for you. As always even TEIN dealers can misdiagnose.

any chance it's a tranny mount? My wifes was making a "thudding" sound on the drivers side. It sounded forward of the shifter but behind the firewall. A new tranny mount cured it. It was only in specific situations it would appear. This was on a '94 SC400 w/ 120k miles. Good luck diagnosing it.
