Just bought my '99 Fronty, it had a noise when test driving it and had a verbal agreement from the dealer that it would be fixed once we could isolate the noise.  It sounded at first like a gear slipping, but the noise was to far from the tranny or gearbox or the diff, to be any of those.  So after driving around for a day or so, it seemed like the noise was only coming on with the A/C.  Driving down the road, about 2500 rpm or such, fans going, then press the little blue A/C button and *grind* there's the noise for a sec.  A/C then just works fine, occasional noise again if you do the same thing.

Dealership checked it out, said there was some rust on the a/c compressor clutch, they disassembled it, cleaned it, oiled it, and put it back and it works fine now, no noise.  My question is...  How would rust get on there?  Sitting at the lot, not running? 

Regardless I'll be keeping an eye on the A/C, seems to be the only issue with this truck, it otherwise is running like a champ.

Well, pulling the clutch and cleaning it didn't do much other than dull the noise down from a GRIND to more of a CLACK like rogrrr here has in his '99...  so it's back to the dealer once again...   methinks a new a/c compressor assembly (with clutch) is in the works here.

actually rogrrr, other than the A/C noise mine is running pretty smooth.  88k miles, no real body wear, new tires - brakes - exhaust manifold - plugs/wires/dist cap... all from the dealer before selling it.  now they are getting a new a/c compressor for it. 

not sure about the issues you're having, i'll check around tomorrow when i'm more awake...
