Ok, I cant be the only one that has screwed up doing this (I hope anyway). I did a rear brake job with new drums, brakes, wheel bearings, seals, and change rear end oil. When I took the hubs apart they had oil in them and running out everywhere. Put everything back together and 40 miles later the rear wheels lock up. WTH right. THE REAR HUBS ARE NOT SPLASH FED FROM THE REAREND. Just because you put oil in the rear end don't mean the bearings are getting any. I went and found me a big hill to park it sideways on so oil can get in the hubs, I let it set there for 15 min then swap sides let it set for 15 min that side. I plan on doing this once a month (call me crazy) but the hubs are not getting oil if you are driving flat down the HWY. That is the stupidest crap designed for a one ton truck I ever heard of. How the heck the bearings going to stay cool with a heavy load on asphalt in 108 degree heat in the summer? Singed PISSED OFF

That video does a great job showing why the MH cover has the predrilled/tapped port for a temp sender at the top of the cover.

those diff covers are known as Clear Gearz.

That's cool!

Somebody tell me why after 40 miles there was no oil in the hubs. This has me scratching my head. The diff was full of oil coming out the hole and nothing in the right hub. The right side also has no rust (clean). Then I over fill and it has oil in less than 1/2 mile. These rear ends are strange.
