I have a problem with my car mainly when driving on the highway(more noticeable has speed increase) the car feel unstable sideway
rocking motion), the only modification done to the car is the upgrade for the frame bushing using the stiffer one from GM and the replacement of the idler arm with the moog part.

I don't know what can be causing this?
Any Idea?

My best guesses would be worn shocks and/or
poor alignment. With tires as wide as ours are alignment is quite critical.

check the lugs nuts, an also check if there is any other part in the stering system that needs to be replace, an check to see if you end links are loose or broken, an then the shocks

...my '95 B-body did the EXACT SAME THING until I installed bilstein shocks! It would rock side-to-side like a damn baby cradle. Get the shocks - get rid of the instability!

Thanks for the info, I double check the lug nut with my torque wrench there ok, the car was align with the B-body.net spec and there is no bent or loose parts in the direction. I order replacement shocks, I went with Monroe Sensatrack because of budget restriction next year I will put Bilstein on it but until then Monroe will have to do (better then worn stock shock). I will have the pleasure of replacing them tomorrow, I will let you know the result.

Exclamation

I had the same problem on my '96 when it had only about 12K on it. Turned out that both front wheel bearings were loose. When I put the front end on jackstands and checked the play in the wheels (just grab them and shake) I had about 1/8" play. I simply added some wheel bearing grease and adjusted them per the FSM. This resulted in NO noticeable play and a rock stable ride.

So check yours and HTH!

Check to see if the upper control arm bolts are on tight. If they are loose the car will wander and may start too lose some of the alignment shims.

Good luck

The new shocks are install, not an easy job to do but once you finds the right tool it goes a lot quicker. After the test drive the result is .WOW, it day and night. The car is very stable now. Thanks for your help [img]smile.gif[/img]
