Torque specs for front control arms & ball joints

[CAArcher]

Does anyone have a Bentley manual that can list the torque specs for the front upper and lower control arms and ball joints? I'm getting ready to replace all 8 control arms and hardware and have been unable to find all of the specs.

Thanks!

Someone on another forum replied to my post there with the torque specs. I'll post them here for future reference in case anyone needs them.

Always replace nuts/bolts if removed. For the upper links, inner nuts/bolts that secure the links to strut tower get tightened to 50 Nm + 90 degrees when suspension is at curb weight position. The upper ball joint bolt/nut get torqued to 40 Nm. Wheel lug bolts 120 Nm.

Inner bolt/nut for lower links are 70 Nm + 180 degrees with vehicle in curb weight position (vehicle on ground or suspension jacked up/compressed to normal ride height). Lower strut mounting bolt/nut to front lower link 90 Nm + 90 degrees with vehicle in curb weight position.

There are 4 different versions for the lower ball joint nuts:
For the M14 (thread diameter in mm) ball joints with 21mm combination hex nut (its washer spins), 140 Nm.
M12 with 21mm combination hex nut, 120 Nm
M12 with 18mm combination hex nut, 110 Nm
M12 with 21mm collar nut (washer is integrated with hex nut), 145 Nm.
