Rear end hot?

[EnLjones]

When I pulled into the parking lot this morning a fellow worker stopped me to let me know that my rear end had what looked to be steam coming from it while he was behind me for the morning drive in. Roads were wet from rain/snow and when I looked under the truck the pumkin was dry but not hot to the touch. I know the fluid is good (recently changed) and the level is good (checked two days ago). Is this pretty much normal or should I be worried? I just turned 100K on the truck two days ago.

Did you check the brakes, I had the brakes on one wheel drag on my 05 without reason. Got really hot and if there had been water on the road there would have been steam. Dodge paid for most of the repair. Still not sure what happened, I thought it might have been a sticky emerency brake.

Running Temp is 100 to 250* 250 is the high side. Generally at 30* axle temp will be 100 to 160* if it gets wet at that temp it will create steam.

I'll check the rear wheels to make sure they aren't hanging up just to be on the safe side, but it they look good then I'll let it go from there, the operating temps and outside air temp makes a lot of sense. Thanks TDR!

Check the brake calipers.

Are you sure it wasn't steam off the muffler (exhaust system) that happened to look like it was coming from the rear axle.

I got home tonight and crawled under the truck and the rear end was warm but not hot enough that I couldn't put my hand against the pumkin and the brake rotors were cold to the touch and this was after an hour run at highway speeds. I'm think the temps or normal and the steam vapor thing is due to the weather. I've got a buddy with a similar truck and I'm going to do the touch test on his truck to see if I can feel a difference
