Today my friend and I removed the d44 from his 72 blazer and dissasembled the entire thing completely to where the only thing left is the housing with the carrier and gears left inside. We didn't pull the carrier yet just because we didn't feel like it. BTW this all started as a simple project where we were just going to replace the old rotted leaf spring bushings now the whole damn axle is out and disassembled . Anyways, we went to O'reily's and got all new balljoints, axle u joints and that's where we stopped. Which bearings do we replace and what the hell are they. I know that there are an inner bearing and outer bearing and some inner and outer seals and races but does anyone just have some part numbers cuz we are having problems trying to explain to the parts counter person what we need and want to make sure we get everything. Thanks for the help.
