It is a very quick jerk then it stops abruptly only when I hit the brakes with a fair amount of pressure >10-20mph or so. Hmm... I thought if the thrust arms passed the wheel shake test they were all good. Pass side does make slight squeaking sound when i go over speed bumps and the bushing does look a little old. There is a tiny crack near the center. If I take a good pic of it would you be able to tell? I have the pass side half axle out right now I just replaced the outer CV boot and about to put the assembly back on.
Totally feels like a bump...
I suppose it's easy enough to just replace the bushings and see if that fixes the problem? Do I have to buy new thrust arms or are the bushings seperate?

Drive the X at about 10 mph and repeatedly give a quick application/release of the brakes, that "bump" you feel is the bushings. Another way to get an idea if it is your bushings is to feel for the tell-tale bump/clunk when you come over curbs and parking bumps. They almost always feel sturdy in a shake test, but if you peek at them with a flashlight, you will see the rubber tearing at the center when they are worn.
But from the sound of it, it is most likely the bushings in question  |
