Hi all, im having trouble with the transfer case i think. Started to pull uneven some time ago. I Changed the oil in the manual gear box, differential and transfer case. It became better, no noise, but not cured. Still pulling uneven and vibrates @ higher speed. After reading forums i think perhaps the transfer case is finito馃様 It was a bit metal shaving on the magnet filler plug. 87000km on the clock. I was talking to a guy who is renovating this Tcases, and he told me there is a rubber bushing on the Tcase that also must be replased, and it is a difficult job? Also he told me that a Mini dealer must re program the new Tcase? To buy a new Tcase is about 2500us, so ive looked @ used ones. Was thinking I could manage to do this myself.. Did anybody change this by themselves?
Im wondering if a Tcase from any BMW would fit? It would make it easier to find a good deal. Thanks馃檪

below uk,

in side there is a wet pack full of wet clutch metal plates these do wear out what really hurts them is un even tyre wear, or tyres not kept at same pressures on all 4 corners, its possible to replace these plates can buy them from bmw or gearbox specialist its part of torque and which wheels get grip while on the move and the plates allow for instant changes is each wheels speeds when cornering etc, ITS VERY IMPORTANT USE CORRECT OIL, i would ask the dealership what the oil is and ensure you have the right one, i have driven cars that came in sounded like the transfer box was end of days, after sticking in the special oil ie its got a set amount of grab allowed ie for these wet plats grip but dont wear away or dont grip because they slip past each other, if someone has added mollyslip that will just make them slip and not grip as such, its not a bad job to replace these plates and all the bearings as well, might need to loan a press or pop to machine shop to push on the odd bearing if they are worn,

Thanks Mike, I used Castrol syntrax 75/90 long life. I was told it is the right stuff. It is working better now than with the factory oil in it. I live in Norway, I have found locally used Tcases with around 20k miles on them, for about 7k sterling. But i like a challange, it would be great to manage restoring the tcase by myself馃檪but i guess the parts i need aint cheap.. What about that rubber bushing, do you know anything about that?

need to speak with a gearbox specialist they know a lot more about them than i would ie what parts cost and what can be replaced and how, i'm sure the transfer case is shared with other cars as most car makers are lazy and inter change drive lines,, ie jeep patriot is same as a rav 4 go figure, some of bmw xdrive stuff gets pushed all over the place as well, i just avoid them these days wont own one dont want to jump to repair them these days as its all just a mine field, car makers dont share info and that just makes things harder to repair them,, best option is replace them and any thing that is electronic on it swap your old case electronic guts to the secondhand case you buy,, autocom cdp plus will read gearbox and reset it, or bmw own software insta d off ebay
