Whine in front end
I have noticed that in 4wd, there is a whining noise from the front end. It seems to be mostly when letting off the throttle and changes pitch if I accelerate. If I can hold a steady throttle, it is much quieter. In 2WD, the noise is completely absent. Should I assume this is a pinion bearing issue? It seems to have developed since I replaced the ball joints, but honestly I don't use 4WD often, so it could be coincidence. I had a leaking pinion seal replaced a couple years ago, but it was quiet after the replacement. Any suggestions?

That would be the transfer case, all transmissions/transfer cases make that noise in really slow gears. My Ranger does it in first. No clue what causes it though, something i want to figure out.

BTW, I did bring it to the dealer, and was told something is going in the ft. diff. or tc, but they were not sure what it is. They recommended I drive it until it gets louder so they can pinpoint it. Then they charged me $80 for "diagnosis." I already knew that much, thanks a bunch. This is why I rarely visit dealers, what a load of crap...

I ONLY go to the dealer if i need Mopar parts in a hurry.
IDK about all AAMCO's, but the one i always go to usually diagnoses for free. They tore my transmission apart a week ago free of charge. I'm sure you can find a place that does free diagnostics.
