i got a 2000 blazer 4x4, and a few weeks ago it started makin a squeaky noise..sounds like its literally behind the rim right where the top ball joint is and caliper, i was told a couple things such as ball joiints, rubber bushings maybe by them if there is any? upper or lower control arm, i greased all of them and still making the same noise and seems it only does it when i hit bumps and its getting worse as i drive...can anyone help me out plz? its driving me up the wall!!!

 

Have you inspected the shock?

 

Replace your shocks and the issue will resolve itself. If unable to replace the shocks, you can test by spraying the shock main rod with some lubricating spray.. Liquid Wrench, WD-40 or the like, and take it on a bumpy test drive. The squeak should be gone, if so, you have a worn shock, and you need to replace it.

 

Replacing them front shocks is a real bear....good luck..did all the way around at 50K. have 101K now...No squeaks..

 

possibly bad hub/bearing...

 

id be willing to bet my truck that its the lower controll arm bushings just repaced mine for the samething

 

My blazer was doing the same thing. When I checked it out, it was just a broken stabilizer link. Replaced the link and the squeaking stopped.
