Front Diff Issue? - PhilD, you there?

[CO Hummer]

Ok,
I power washed the diff. It looks so clean I think I could sell it on eBay as new.

Owner's manual say to put SAE75W-90 oil in there. All WalMart has was this SAE80W-90.

Is this OK to put in there?

Thanks Phil.

I was going to use the "220, 221 whatever it takes" philosophy, but I held off and didn't put any of the 80W in. I'm gonna get some Royal Purple.

The diff is so clean that I could eat off it right now.

A lot of it looks like Engine Oil!----Is the Skid Plate removed when the Oil is Changed?

Cleaner Leakage!

No. I take it to Jiffy/Retard Lube. Those idiots get oil all over place. That a good point, Z. It's possible that it's leakage from the oil change. I'll be monitoring it. Maybe I should set up a diff cam.
