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
You definitely need a parts washer. Plus, they're dirt cheap--pop up used on KSL for $50ish regularly. Even brand-new they're cheap from Harbor Freight.
haha jumped my ifs truck.. the whole ifs caved in, the drive line compressed, literaly broke the tcase in half and took the corner off the adapter, luckely its broken in a spot that really doesnt affect the adapter
its jb welded right now, has been that way for a minute, ill admit, it isnt the best, but it doesnt leak at all, i really dont want to fork up the coin for a new one, and like i said, its just the corner. the crack does hit an oil port just barely but i used a bunch of jb weld there. ill post a bunch of pictures of it tonight
