I'm having a stupid problem. The past 6 months my steering has been messed up and felt like it would pull one direction and then another. My front struts were bad(knocking and bouncy). So I put on new passive struts with new mounts, springs, and stabilizer links on both sides. The front passenger side started popping under tight turns. I figured it was a tie rod, but took it for an alignment anyways. They adjust the struts and aligned it as good as they could and said the outer tie rod is bad. I ended up changing the outer tie rod on the passenger side and solved the popping, but still had the pulling problem. Tie rod started popping again and changed it again. I then noticed the inner tie rod was bad so I changed it. I had no more movement in the tire when the car is jacked up, but I still had the same problem. The ball joint looked bad too so I changed that too. Now, I'm to the point of where when I give the car under light throttle the car will pull to right, but coasting or when I let off it pulls to the left. I don't have any play in the steering wheel and both tire don't move when on jack stands. I also had the tire balance when this started happening and also changed the wheel hub too. All of that stuff was done on my passenger side. Plus I still need to go get another alignment too.

This is on my 1992 Cadillac Seville STS. Anyone of has suggestions or advice?

Jack up the front end and support both sides with jack stands. Rotate one tire, does the other tire turn in the opposite direction?

I just tried that and when I turn one wheel by hand, the other wheel doesn't turn at all. The same result for both sides.

On the passenger side, I took off the rim to find out why I started having a grinding noise. The shield with that holds the ABS plug had been scraping, but I still took the brake pads off anyways to check them better. After I put the brake pads back in, without the brakes against the rotor with the tire on and bolted down, it felt like the wheel hub was moving when I shook the tire. I'm starting to think the wheel hub went bad again.

I also checked the control arm bushings and they looked ok. I check the strut rod bushings. The passenger side was ok, but the driver side looks bad. Funny thing is that side feels ok and doesn't have any sound. The other day, I was turning real sharp backing up and the passenger made one pop sound, which might have been the outer tie rod.

I'll probably wait till next weekend and change the passenger outer tie rod again, both control arm bushings, both strut rod bushings, and maybe the balljoint and outer tie rod on the driver side for good measure.

Do you know what it means when the other tires does not turn? You may want to drop your trans pan and look inside. I think your diff is the problem.

Oh great, maybe I need to find a different car.

A diff is easy to change, a few hours.

I've notice I'm getting a clunking sound on bumps and when I turn sharp backing up I'll hear a spring sound. Also when I try to drive in the rain, the right tire starts going haywire and popping.

I'm starting to think the strut mount is bad and the spring might have not been installed properly. I might have to throw on one of the old struts(the one that wasn't clunking when I took it off). I know I should do it, but it'* in worse condition in it'* present state. The struts, springs, and mounts were new a couple months ago and were from strutmasters.com. I'll have to talk to them and probably ship the strut back.
