I just bought a 1999 jeep grand cherokee from a guy, he was telling me that he had to replace the whole transfer case because he used fluid in it that wasnt made by jeep, thinking they were ripping him off. So maybe you put in an off brand fluid in it?

Sounds like a transfer case problem. But I can't verify that from here. Coupler is inside the unit on the output shaft and needs teardown to get to it.

Just bought a 1999 4wd jeep grand cherokee with 215k miles on it, what is some things i should do/replace to this jeep?


Check all the fluids and make sure they are good. i.e. diffs. oil, transmission, coolant, transfer case fluid, air filter. Use high mileage oil. Check the belt for cracks, usually it will start squealing a bit when it needs to be replaced. Tightening it will not help.

When I put my 2005 jeep grand cherokee in reverse and turn at the same time it clunks in the rear end, the service 4 wheel drive light came on and the service electric brake system light came on


I have the same vehicle, with the same issue. I had put the car on a rack and lifted it to pin point the cause of the clunk when shifting from park to reverse or reverse to drive. I found that the front diff mounts were grenaded, meaning they needed to be replace bad. with these mounts being bad it was causing the front diff housing to slam the frame up and down when shifting from park or reverse to drive. this is pretty expensive to fix, your talking $160 in parts and $540 in labor. I also had the service 4WD warning display on my dash cluster, i had the code read. It came up as a bad solenoid in the rear diff. this is about $200 parts and labor to fix. Also, dont know how many miles are on your jeep but if you've ever sub-merged your axles under water or if your over 60,000 miles you need to replace your gear oil in the front diff, rear diff and transfer case. This is a little costly to have a mechanic do as well because you're supposed to use synthetic gear oil. For a shop to do it you're looking at $360.

Setting up a differential is not just bolting in new parts...it requires setting gear lash, bearing pre-load etc. Assuming you did all this, have you checked the transfer case? an internal coupling failure will give you similar symptoms. What did you find wrong with the differential? Is the rear diff the same EXACT ratio as the front? Do you have the exact same size tires front & back? Did you check the obvious, such as the condition of all universal joints? I can't see from here so I have to ask these questions... Also...did you check the brakes to make sure that a hose has not collapsed and is causing brake not to fully release?

Transfer case knocking


These transfer cases do not have plastic pumps. Do have the transfer case looked at by Jeep tech, it could be as simple as an adjustment on the lever.

1996 jeep grand cherokee ltd problem with transfer case because of different size tires


You should have the same size tires in the front and back. By having 2 different sizes, you are changing the gear ratios between the front diff. and rear diff. You could wipe out the t-case especially if it is full time 4wd.
