Front suspension

sounds like bearing problems you need to look also at the inner boot for leakage rotation and wear...next when the car is lifted you can hug the wheel and shake it some one needs to be clear and look under the suspension when you do this look at the lower control arm bushings and look at the stabalizer bar bushings..im me if you need more help

Jacking car on frame rail, the front end should be very tight. No play in tie rod ends, ball joints or wheel bearings. GM has sloppy front end parts.
