LMR Axle Bearing install

LMR - 8.8 Rear Gear SUPER install kit by Yukon 

It doesn't matter if you're building a performance electric or performance 5 Liter you're going to want to replace the axle, carrier, and pinion bearing when installed a new gear set.  None of the EV team members have ever replaced any axle parts so there was plenty of room to learn.  Late Model Restoration supplied our team w/ ALL bearing and shims need to complete our axle overhaul along w/ a Ford Racing 4.56 gear set and Royal Purple oil.

After the original axle seals and bearings were removed and the housing cleaned EV team members began the rebuild w/ new bearings.

LMR T-lok rebuild

Carbon Fiber T-lok rebuild

You can't go to the EV Challenge, VIR, or the local dragstrip with a mustang doing a "one-wheel-peel".  Late Model Restoration Supply provided our Electric Fox w/ several parts to complete a rebuild and regear on our 8.8 axle.  One of the parts we wanted to highlight is the carbon fiber t-lok clutch disks.... what a great part!

Here you can see the carbon fiber clutch material on the disks and the shims.. also comes w/ a new cross pin bolt.  Ours was broke but luckily we were able to use a punch to spin the old one out.  Also provided are shims (upper right).

Not your average 8.8 differential... this diff. was removed from a late-90's explorer and is made for 31 splines.  Also notice the clutch disks soaking in friction modifier.  After the install we had NO noise or pops.  We did let the disks sit overnight.

One of the most tricky parts to install is the S spring.  Notice how Spencer used a hose clamp to  close the spring then used a hammer to install in the differential.
