A/C siezed up
A friend of mine has a 1998 f-150 4x4 with a 5.4 v8. He stopped by the house yesterday and when he went to leave the truck wouldn't turn over. The A/C compressor bearing seems to be frozen and wont let the motor turn. Is it possible to bypass the a/c unit using a belt from a non a/c truck? or is it a bit more complex than that. Also is it possible to just replace that bearing rather than toss out a perfectly running compressor?
Thanks in advance for any help

Probably, just the pulley bearing fail. Been there, done that, got the ride home on the flatbed with my old 5.4L 97 F150.
To verify, remove the serpentine belt and see if the engine cranks. If it does, shut it down and check the compressor pulley by hand.
The pulley and clutch can be replaces with basic hand tools plus a 90 degree inside snap ring pliers. It's not hard. I did mine in 30 minutes in the gravel driveway. Hardest part is getting the darned snap ring to cooperate.
Recommend you use Motorcraft parts instead of the cheap stuff from who knows where.

Projectsho thanks for the reply. Of course nothing is ever that easy, I removed the compressor and found the clutch was toast. The front bearing came out in several pieces and the rear bearing is also no good. So it is off to the junkyard for a replacement.
