If you're talking about the paint peeling off of your rearend cover, I think it's just crappy paint. I know lots of folks get them powdercoated in custom colors or get a maghytec.
FYI--I have 95K on my truck, abuse it at the track occassionally, tow occassionally, and haven't changed the rearend oil yet. I know shame on me, but I read it was lifetime (yeah right) and I'm fixing to put in a Truetrac anyway.

If your confident the paint bubbleing/flaking is new, I would just change the oil. Its a fairly easy job. Once you have the cover off, inspect for metal shavings and that your gears do not look wildly discolored. I think there is an additive you should add too in addition to the gear oil.

Hot Rear End
Today I was looking under the rear of truck and noticed the paint had blistered on the rear end, is that normal or should I be concerned? I only have 15,000 miles on my 6.0 and pull a 10,000 lb toy hauler several times a year.

The rears do get hot. Definitely hot to the touch. I'm sure it doesn't do paint any good. Especially if it is crappy paint. I measure the temp after I drove on the highway and it was about 140 deg F.

It's pretty normal for the paint to blister on the differential covers. I don't think it's a sign of a heat problem or anything like that. You can remove it and have it powder coated as a good alternative to the paint.

Better yet there is a FORD OEM aluminum finned cover that will allow better cooling. If you look at the 08s you will see the cover I'm referencing. I got mine locally for $40 +tax and if you are intrested I bought an extra I'd be willing to sell for the same price + shipping.
