Hello, I did the search feature but i may have missed what im looking for--Just got my car back from the shop for a newer than listed cam--Now i have a grinding noise--my son took off the belt, noise was gone,put back on, noise is back until car is reved. My son sezs its the a/c compressor bearings going out.Said it was also twisting my belt--Can you just replace the bearings without replacing the whole unit? Thanks Dwayne

There are places that can overhaul them but it's usually around the same price to replace it with a new part and be worry free. It may be another pulley though...may want to look into it farther.

Also make sure the AC system was properly recharged. The compressor is lubricated by oil in the system. Way back before I started doing all of the maintenance on the car myself a shop had discharged the system and didn't re-charge it, burned out the compressor actually froze up the pulley and started smoking very badly.
