Here is my Step By Step Guide on how I swapped out my stock diff covers for new tougher diff cover.
Tools & Supplies
- Drain Pan
- Riddler Manufacturing Diff Cover & hardware
- Lub Lockers
- 3" Ratchet Extension
- #9 Allen Wrench
- Flat head Screwdriver
- Razor Blade Scraper
- White rags
- 2.5 Quarts 75W140 Gear Oil
- Brake Parts Cleaner
- Empty gallon water bottle
- Mechanix gloves
- Plastic gloves
Remove the Lowest
I used the 3" Ratchet extension for this. I was not ready for the horrible smell once the oil came oozing out. Nor was I quick enough to get the drain pan under the draining diff. I got a little dirty. Next time I will not use something so deep. Then I will be able to keep the drain pan in position while I removed the plug.
For Several Minutes
Remove all Bolts
from the Diff Cover
I was worried about this part. I usually have a difficult time loosening bolts. But with my Mechanix gloves, and a lot of determination, I did it! It took longer than most, but I persevered.
Pry Diff Cover Off
the Housing Unit
I used a flat head screwdriver and a mallet to get mine off. Luckily for me there was some small gauges from the rocks. This allowed me to get the screwdriver in between the stock diff cover and housing unit.
Completely, 100% completely, Remove the Old Gasket on the Housing
This is critical for a good seal when putting on the new Diff Cover. It was the most time consuming of all the steps. I wanted to make sure I removed every bit of the old gasket "goop"
Clean the Entire Gear Assemble
Attach the Lube Locker
Line up the lube locker onto the diff cover. Then carefully get it ready for Step 9. This was a little difficult trying to do without another person.
Attach the new diff cover to the housing unit.
Hand thread the bolts according to the Lube Locker instructions (star pattern)
Tighten down bolts evenly by alternating to assure the plate is mounted evenly with the same pressure making sure each bolt becomes tight but not super tight.
Put drain plug back in using #9 Allen Wrench.
Fill the rear with 2.5 quarts
of 75W140 gear oil
And what Jeep modification wouldn't be the same with out extra parts. Make sure you keep them because you never know when you will need them
