2009 titan TT diff install

**spoolie** · 10-22-2012, 03:22 PM

Thanks to a forum member for giving me a great deal on this TT diff. I've picked up the extras needed for in the morning. Has anyone called Nissan and asked for carrier bearings? LOL they are idiots and only want to sell the entire differential.

I called Detroit and they said to fill with factory spec oil for the axles, but they also told me the TT diff likes regular plain 80w-90 gear oil. The lps had the Royal Purple on sale. Two new bearing, red loctite, and RTV.

I'll post pictures of the progress step by step, it's very easy.

This was the simplest diffs ever. Literally 50 mins to install, it took the machine shop longer to press the bearing on than the diff.

First, you need these bearings to install on the TT diff, it comes bare.

Jack the *** end up and place jackstands under the axle. Put chocks on the front wheels and don't set the parking brake.

Zip the wheels off.
Remove 2 bolts and remove brake caliper ( it can hang there).
Pull the rotor off.
Remove 4 nuts off the back of the axle plate.

Attach a slide hammer to the wheel studs and pull the axles.

Drain the rear diff using the 3/4 square rachet head plugs.
Zip the bolts out of the diff cover.
Tah Dahhhhh..the ****ty open diff.

Remove the diff, loosen the adjuster and remove the 4 carrier cap bolts. The diff will almost fall out on you, catch the bearing races and save those.
Take the TT and your bearing to a press and install them taper out.

Zip the 12 bolts out from the TT diff and apply RED loctite and re-install them.
Remove old ring gear from ****ty diff.
Install ring gear on TT diff and use RED loctite on the bolts.

Put the bearing races back on the bearings and slam her back into the housing.

Put the carrier caps back on snug.
Make your adjustment via the carrier adjusters.
Torque the caps down.
Apply glue to the diff cover (after cleaning it).
Replace cover bolts.

Push axles back into housings while turning them slightly.
Put rotors back on.
Put calipers back on.
Put wheels back on.
Torque wheel nuts.
Fill diff with 2.5 quarts of 75w-140 syn. fluid.
Put plug in.
Take off jack stands.

Go tear your tires up. I didn't, tires are 300.00 per.
