HELP - - swing arm bolt torque value

[Mangostene]

I've done quite a bit of Google search on this and the only hit I received on a torque setting is the link below. Can someone please tell me if the torque value outlined for item #15 is indeed 115Nm (or 84 lbs)?? The website that provided these values came from: https://how2fixvideos.com/BMW_suspen...que_specs.html

I followed that very same torque setting and I ended up snapping the bolt in half! The torque wrench never clicked. If #20 (per the link) has a torque value of 58Nm, shouldn't #15 be the same?? Thank you in advance.

First of all, #20's torque value is 115Nm (85 ft-lb). #15's torque value is 58Nm(43 ft-lb)
The big bolt, the swing arm to wheel bearing carrier, torque value is 256Nm (189 ft-lb)

Rear control arms #10 to subframe are 110Nm (81 ft-lb)
Rear control arm ball joints to wheel bearing carrier 142Nm (105 ft-lb)

Front upper control arms #6 to the subframe are 60Nm (44 ft-lb)
Front upper control arm ball joint to bearing carrier 65Nm (48 ft-lb)

This is from an online version of the TIS. Also, take note of "normal position" ....

Wow. Completely off. No wonder the bolt snapped. Thank you for the clarification.

I did notice the "normal position", I take it that means to tighten while pre-loaded at ride height?

Yes, snug all the bolts up, drop the car back on the ground, then torque them up. The torque values I posted were off of the Bentley manual.
