hi everyone I justed changed my rear differential cover because it was leaking. I got a new one from advance auto parts and cleaned everything up and put gasket sealer on it and put on the new cover. and by the way I put fluid in and now for some reason somthing don't feel right. 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!

Is the gear rubbing against the cover?

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!

Does anyone know at what mileage this should be done? I couldn't seem to find it in the owners manual. Thanks for the write up, by the way.

some internet talk suggests that it be done ever 50k or so, but depending on how hard you use your truck that could vary. mine has 80k on it and i'm sure it's never been done so guess what i'm doing in the near future?

Old thread but I figured I'd ask. How does one know if they have a limited slip diff?

I have a 2001 XLT 2.3L, Auto with 4:10 gears.

Thanks,
-Nigel
