Help with Front Differential mounting bolt torque

[lilix1]

Guys Im new to the group and need some help.

Do you have information on regards to:
- Torque spec for (Qty 4) the front differential bolts that go against the engine block?
- Torque Spec for the Engine support bolts that go against the engine block?

My car is a 2013 X1 E84 AWD with the 4 cylinder engine (N20)

Thanks in advance!!!!

Hey lilix1, sounds like you are doing a timing chain job? If you are, I attached a nice walk-through post. It is based on the FCP Euro videos with specifics for the AWD cars. I used it for my 2013 N20 xdrive, pretty straightforward.

Unfortunately it doesn't mention a specific torque spec for the front diff mount bolts but I'd say at least 30 ft-lbs is needed. Use judgement, tighten everything equally before stepping up the torque, and you won't strip a bolt.

For the engine supports, why are you removing them? Is the engine coming out of the car? I found it's necessary to drop the subframe in order to move the diff and remove the oil pan.

Hey Thanks for the information and for sharing that other link. I did follow a mix of sources (including that) the timing chain is down, now Im just putting the car back together. Thanks again for the advise

The maintenance manual does not make this easy. They list a torque reference number, and then make you track down the value for that in a separate table. That said, it appears to be:

4 bolts connecting diff to side of oil pan or engine block (it's been a while since I did this): 65 Nm
Bolts connecting engine support "arms" to side of block: 38 Nm

Hey Thanks!!! I used that information and managed to get everything done, drove the car for a while today and sounds great. Will post an update some time later to report any issues.
