My Camaro Z28 has been squeaking. I have changed pads, machined rotors, cleaned

[Charles L]

and greased everything ? What could it be? When put on lift it doesn't really squeak. Could it be the alignment? mechanic said it was not bearings. Don't know what to do and getting very frustrated. Problem is on rear driver-side.
its not brake pads rotors or anything that has to do with lubrication.

Hi, you need to give us more information....does it squeek when you turn left or right? does it squeek when you drive straight...accellerate....brake?....... power steering fluid ?
Could be your U joints...change or lube the joints...
Check your belts and pulleys.....check for cracks in the brackets and or pulleys.......Did you hit a squirrel going down a country road? Good Luck
