I am installing 2 new thrust arms in my '06 330i due to blown bushings. I have the Haynes manual (which sucks) and it is giving my a ball joint torque setting of 122 ft. lbs. This seems really high to me. Anyone have a bentley or TIS that could confirm the torque settings for the ball joint (and the bushing while your at it).

I would greatly appreciate the piece of mind!

Thanks!

Bentley states: Tension strut to steering knuckle=165 nm(122 ft lb)
Tension strut to subframe=68 nm(50 ft lb)

Thanks man! Really appreciate it! This is the first thread to publish those settings.

On the tension to subframe, does it state 68 nm plus 90 deg?

Yes, it also says-M12 10.9 (replace with new) 100 nm(74 ft lb) +90 deg

Perfect...same as Haynes. So I guess Haynes is more than just scratchy, expensive toilet paper...

For Tension Strut to Subframe, the manual gives two torque settings? Which one do you use? Are there different bolts used depending on model car?
M12 8.8 50 ft-lbs + 90 degrees
M12 10.9 74 ft-lbs + 90 degrees

This is the way I understand it:

The torque setting is derived from the grade of the bolt. 10.9 and 8.8 are bolt grades. there should be markings on the bolt that indicate which grade it is...based upon that, you can determine which torque setting is appropriate.

Cool, thanks!
