Rear Gear Ratio Upgrade - Part Two

The shop installed the new set of Motive 3.80 gears in my differential in just a few hours.  The gear pattern paint looks good from my limited experience of having one other gear set done.

My schedule has been very busy lately so the assembled carrier on the garage floor for a few weeks before I installed it this weekend.  I cleaned it some and put a few light coats of the original paint back on the carrier to cover some scratches left from the machine shop.

The carrier is very heavy and it took a few times of lifting it before I was able to get it up and into place with the exhaust still installed.  I used a new Fel-Pro gasket with a light layer of RTV.  Additionally, I used a new set of copper washers and locking nuts.  I was not as meticulous as in the past with cleaning up everything after the install (brakes, driveshaft, etc) but the job is done.


I sold the old set of 3.25 gears on eBay which paid for the installation of the new gears.  No reason the have the 3.25 laying around as I do not expect to switch back.
