differential flange torque

[b.u.ti-ful]

Anyone know how tight the bolt that goes through the differential flange should be?

Is this thing supposed to be able to move in its slotted hole?

Or should it be cranked down?

I'm not exactly sure which flange you are talking about, so here are all of the final drive torques in the bentley-

drive axle to final drive flange-
m8 torx- 47ft-lb
m10 torx- 74ft-lb

final drive carrier to body- 57ft-lb

final drive to final drive carrier(m12 bolts)
front mounts- 70ft-lb
rear mounts- 57ft-lb

Thanks for the reply.

There is a giant rubber mount coming off of the differential cover.

It mounts to the car's body.

It has a bolt going through it.

That's the bolt I'm wondering about how tight it should be.

Somebody else correct me if I am wrong but that is the final drive carrier to body. The final drive to final drive carrier are the 4 m12 bolts that mount the diff to the mounting assembly. Should be 57 ft-lb's. It should be tight and any movement of the differential is absorbed by the bushing..

I agree with mohaughn, it should be, as the Bentley describes "final drive carrier to body". 57 ft-lbs. / 77nm. That's for a normal E36, but I don't see why a 318ti would be any different.

Sounds good to me.

That spec means crank it down, which is what I did.

Thanks for the help.
