Front Diff Issue? - PhilD, you there?

DS = Driver's Side

Yep, that's the check/fill plug. The other is the drain. Fill to the edge of that hole (a little is likely to run out)

It's in your Owner's manual but something like 80W Synthetic Oil

Wait and see what Phil says. It's probably worth it to drain all the front diff fluid and replace it with all new.

I checked the bolts on the diff and tried to tighten them (from the PS ). The one near the rear tightened about 1/4 turn. The other were very tight and I didn't apply any more torque. That might do it!

I'm gonna wash it off, then top off the fluid. I'll see if it continues to leak. I just had the fluid changed in my diffs this spring. Man I feel like an idiot because it looks so simple to do myself.

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.
