Ford 8.8 rear axle
At this point I decided to try my first big boy mod. I dropped in a 1997 Ford 8.8 rear axle. This is quite a bit beefier than the stock Dana 35, and would be a good basis to build on. I rebuild the limited slip in the Ford axle and decided to run that for a while until I can afford a select-able locker.
Limited slip with 3.73 gears (matched my Jeep)
As it looked when I took it home:
The S spring is what applies tension to the clutch packes (one on each side of the spring). This is the LSD (limited slip differential).
It took more work than expected to clean this thing up - that and about 10 cutting wheels.
Welded up and ready to install
A new solid brand diff cover and some RTV. The stock diff cover is paper thin.
These are parking brake cables from a Jeep ZJ. They mate up perfectly to the Ford 8.8
Axle installed in the Jeep
Here you can see the Spicer yoke adapter that allows my Jeep driveshaft to adapt to the Ford 8.8.
