1995 G20 shoty. So I recently had the entire suspension system replaced and aligned this past week. This weekend I took the van out for 600 mile trip. The noise seemed to get more frequent over the weekend until it did it all the time now. I am consistently getting multiple knocking sounds from the passenger side area ONLY when turning left. There is no noise when going straight and no noise when making lane changes. The knocks only come when turning sharply or at low speed. I also get the knocks when parked and turning the wheel. I watched from underneath while someone moved the wheel back and forth and cant noticeably see anything moving around. The noise seemed to get more frequent over the weekend until it did it all the time now.

Is there something that may need to be tightened down? I have also read it could be a bad wheel bearing? Im pretty sure this van has a hub rotor with the bearings inside.

Drove it to work just now, with just me in it (no wife or dogs) I can definitely hear some squeaking creaking going over bumps and when stopping and moving from a stop, all from the passenger side in addition to the knocks when turning left. I will double check the lug nuts and brake pads tomorrow.

I second the pad clips or a bolt in that area. I had the same problem back in the spring.

Well took another look today. You can clearly see the upper control arm moving front to back on the bushing. Im taking it back to the mechanic today so hopefully this is an easy fix but im thinking not so...

You want to bet he changed all but these, so he can get another tear down charge. They should have changed them when he had it apart before.

The bushings are all new as is the rest of everything else. The factory arms maybe had 100k on them and the original bushings were not completely toast. He took the time to sandblast and paint them for me so I don't see him intentionally reinstalling bad arms, unless he is that sneaky. I tightened the two nuts best I could and it definitely helped. Heading over to the shop now to see what the story is going to unfold to.

Sand in the A arm bushings is a bad thing. Maybe that caused premature loss.
