Check the steering rack bushings. At that mileage though, I'd expect them to be completely shot and causing delay in steering plus the thud sound you hear. Another thing you wanna check is the control arm ball joints.

That! I didn't have bushings in mine cuz they were so shot I accidentally pulled it out, I had a thud turning, I just ordered the daizend from TM engineering for 57 shipped and it helped.

I spoke eith the previous owner.. and whih turn out he a very honest guy.. anf he said sometkmr in pointnwhen he owned the car. He did replace the steering rack pinion which meant the whole thing . But i dont know if he rrplacr the bushing or not. So yea .. do u have a oicture of it.

There's plenty of info around if you search. You can also see it in my thread. But I think Daizen has gone out of business already since 2010. Might wanna order it somewhere else.

control arm bushings are able to be bought from TM Engineering, I bought my Daizen bushings from them and i got it within a week. Check to make sure its your control arm bushing and not your ball joint, If it does happen to be your ball joint your arm will need replacing and then the new control arm bushings you just installed will go to waste unless were able to get em out without damaging it. I havent looked into the control arm bushings yet, mine are still good, my thud going forward and reverse is my drivers side ball joint so ill be paying a visit to my local wrecking yard soon.

To be honest i would hust want to get a whole new arm an then buy the bushing for it and install it at once.. cause i hate it .. well i jack the car up and wiggke the wheels and it seem like it not the ball joint because it doesnt have any play innit.. or i will buy anused arm and make sure checm the bakk joint

if you can afford new supra Lower control arms that's the way to go, they are also less expensive than the lexus ones and will improve the handling some and you don't have to worry about your balljoints later on. I replaced the control arm bushings it was a lot of work to get those bushings out, If I could go back in time I would have just got new arms and replaced them it would have literally taken half the time and a quarter the effort. those bushings are horrible it took 2 of us to get those things out with torches and various tools and then the cleaning, and burning rubber smells horrible.. all that and still an old balljoint.. but it did solve my problem and the balljoint still seems to be good but be prepared to get messy.
