I got the rear case rebuilt and ready to be mated today, here's how it went:
I started by tearing it apart
I checked all the gears out, and made sure everything was wearing together good, I made sure to inspect the 4.7 gears close
Here's a shot of one of the 4.7 gears next to a stock gear
I cleaned the housing up and made sure the larger gears had enough clearance, it looked like the previous installer did a pretty good job clearancing the housing
Next I individually cleaned every bolt any bolt with rust were thrown away and replaced with good Toyota ones from my stash
Another part of the housing, notice the bearing, I always like to add a little grease to the dry bearings and even a bit on the gears during install
Here it is all assembled the back will remain off awaiting the disconnect from trail gear
