Transfer case and diff plug torque specs?

[John Galt]

Does anyone have the BMW factory torque specs for the fill and drain plugs for the front and rear diffs and transfer case for my 01 3.0 X5? Also, the torque specs for the skid plate bolts would be nice too. Thanks!!

I was never able to find the specs for those, but they are steel plugs in aluminum housings, so use restraint. If I recall the plugs actually taper outward the closer to the head you get.

If the drain plug is not leaking lube, you are fine. I would make sure it is still snug after a short test trip.

Where would I get these specs? Factory service manual?

I saw torque specs for those plugs somewhere, don't remember where, but it was 20-25 ft-lb.
I didn't torque my plugs when I changed the oil, just snugged them up with a 3/8 drive rachet, no problems.

I've seen 20-25 for the tranny plugs, but I don't know if those are the specs for the axels and transfer case.

I did the transfer case this past weekend; used Redline D4 ATF. I will try to do the diffs this coming weekend.
