A/c compressor bearings going out on 99 F250 crew cab, can I rebuild them or Have to buy new one?
Hello all 
I have a '99 F250 Crew Cab 5.4 auto 4x4, and the ac started making some serious grinding noise at the belt and has been working on and off blowing cold then at times blowing warm air. Was told it might be the pullel bearing going or gone out. I was wondering if this is something I can rebuild or if I need to get a reman? At least it got me thru the hot summer so far

Pulley (with bearing) is relatively easy to replace. Replace the clutch hub while you're at it. Use Motorcraft parts for both, around $100 from forum sponsor Rockauto.
If the pulley bearing fails all the way, it will lock the engine up. My old 97 5.4 got a ride home on a flatbed after I waited too long and the pulley bearing froze.

Considering I bought a brand new motorcraft ac compressor in the box on ebay, by looking up the motorcraft part number on thier website, and searching by that partnumber for $150 plus shipping, you might try that first. The bearings locked up and siezed when parked, preventing the motor from starting because the belt acted like a brake. Cant get better than new.

If the failure is limited to the pulley and not the compressor internals, you'd have to carefully compare the relative costs of replacing the whole compressor with it's added costs of the servicing the sealed system vs replacing only the external mechanical parts.
You likely already have a shim that you'll get in hand when you pull the hub off. However, it certainly would not hurt to have a pack of the shims on hand.
