How To: Install A PML Differential Cover

Here is how to install a PML differential cover on an 8.8 axle

Tools needed:
  • Socket set
  • Ratchet
  • Allen key set
  • Scraper
  • Flathead screwdriver
  • Drain pan

Parts neded:
  • PML cover
  • Black RTV
  • Brake parts cleaner (non-chlorinated)
  • Blue Loctite

*As you can see the axle was previously drained of fluid and was on jackstands, however the installation process is the same.

This cover features raised fins for added cooling, as well as 0.6qt over stock fluid capacity. It also features an added magnetic drain plug, fill plug, and level check hole. There is also a small raised portion on the right side which can be drilled and tapped for a temperature sending unit.

The cover is available in black powercoated (as shown), polished, and as cast finishes. A 7.5 version is also available for those with that axle. For more information on them click the logo below.

From their website,
Quote:
  • 3/16-inch thick wall construction to add strength to differential housing
  • 3/8-inch thick gasket flange will not bend when bolts are tightened
