Hoping the more experinced out there could assist me. Since acquiring my FJ60 several months ago, I have been hearing a "wa, wa, wa, wa" and trying to dissern just where it was coming from. After checking most things and replacing the rear outer wheel bearing, a friend of mine from a transmission shop thinks its the carrier bearing, maybe called the inner axle wheel bearing. My question is: Is this a fairly easy replace? Do I have to touch the "sensitive" ring and pinion or is it better left to the experienced. I did replace the outer rear wheel bearing without any problem.

The third member needs to be removed from the housing, and the old bearings removed, and new bearings installed. Then you'll need to set the backlash using the adjusters, and a dial indicator.
It's not too hard, if you have a dial indicator, a tool to adjust the adjusters wheels (can be made from bar stock and bolts, or use a spanner wrench), and a way to hold the third member. It also helps to be young and strong when removing and reinstalling the third member (old and stupid works for me, but it's not recommended)
I have done it many times for installations of air lockers. It doesn't require touching the pinion, which for me makes it easy. The TLC differentials aren't shimmed on the carriers, they use adjusting nuts like a Ford 9", so you don't have to mess with the bearings once you have them installed.
I follow the factory service manual directions, and I don't think I'd attempt it without the FSM.
Since most of the work can be done on the bench, not under the truck, it is more pleasant and many repair tasks.

You need to have a press to press the new bearing on and a clam shell to get the old bearing off.
