Hey everyone, I have another quick question on the front differentials on the Escalades. What are some of the warning signs to look for to tip you off that you have a front differential getting ready to cause problems for you? Thanks, just wanting to know what to look for on these.
Never changing the oil, that is one of the cheapest ways to keep it running longer. If you are starting to get a whine, of course by then it's pretty mych too late. Changing the gear oil every 20-25k miles and using synthetic oil will help.

A whine when it is driving? Not sure when you are meaning by the whine.
When the bearing are going bad you will get a whine when you give it gas or let off the gas while driving

Ok, thanks, not getting that and have just changed the diff fluid so I'll have to keep an ear out for it. I am getting this "wheel hop" when I am turning at very slow speeds at full turn. I have turned off the stabilitrac, same thing, replaced hubs, same thing. I have driven a 4WD before and it is not the normal grab, feels like a shudder or vibration in the steering. Out of ideas, not sure what it is, but it does not happen when I first start driving, only after I have been driving for about 20 minutes or so.
Look in your phone book for any shops that are 4 wheel drive shops, they maybe able to help you the most finding your problem.

Called A guy and he just said it could be fluid needs changed in Transfer Case? Sounds like a stretch. Transfer case vs diff, not sure.

Truck is a 2002 AWD with 6.0. Really having trouble with this one, truck runs great for the first 15 minutes then when I start turning sharp at low speeds bad hop or chatter on the front tires, I have replaced hubs, rotors brakes. Not wanting to have a mechanic "try" things until he finds it. I know that is what I am doing but rotors needed done anyway and I don't have a huge labor bill.
That is strange that when it heats up is the only time it does it, something is binding, maybe a low fluid condition, just a guess

I changed the front diff fluid, I could check it's levels again. Should I change the transfer case fluid and if so what kind of fluid should I use.
