Spicer Rear Diff Cover Install

[@10hunterLab]

Your truck looks like a standard height lift. If so, you should have used the lower fill port for fill and level check. The upper port is for lifted and high pinion angle vehicles. You have overfilled your diff. You might want to check it out.

Thank you for the concern, Gary's truck has a 6" rough country lift. He did all the research and was very sure of what he was doing. Again, thank you for keeping an eye on us, much appreciated!

Looks great is it made of cast iron or aluminium?

Cast Iron I believe, and thanks!

Spraying degreasing agent on bearings that are to remain in service is asking for bearing failure. I cringe to think you ran a wire wheel on an open differential housing.
