New u-joint did not solve the problem. It's quieter now, but not gone. So I guess I'm looking at...pinion bearing (both t-case and rear diff?) and what else? Wouldn't be brakes or anything since I didn't hear it in front wheel drive, right?
David, your right. I didn't notice that he was using the singular form of u-joint. Heck whats another few bucks. Change the other one too. It's a lot cheaper than dropping the 3rd.
