I felt the cover after taking a drive to the mall and the cover felt hot is that normal. I want to take it apart and is if its rubing but I dont want to have to go through all that work again. so if anyone can give me a heads up on this that would be great!
You'll have to be more clear on "don't feel right". What fluid did you refill with?
As far as the HEAT, it's normal, and I'm sure if you'd checked BEFORE the change, you would've felt the same level of heat, i.e. VERY warm, but not "egg-fry" hot, NOT glowing... amirite? Think about it: ALL the kinetic energy to move your 4,000 lb. truck is CONCENTRATED on a couple gear teeth (at a time) squeezing HARD on that thick gear oil... plus it's also your rear axle-bearing lube... so yeah, a small % of that mechanical E gets converted to thermal E... not to worry... Mr. Joule and Mr. Watt worked it all out in the 1800s.
Just to give you an idea of how moderate the heat level is, back in the 1980s, Ford was using PLASTIC diff covers on the Ranger.
Anyway, if a gear was rubbing against your (aftermarket... Brand?) cover, well, that would be one crappy cover!
