Torque Specs?

ONDEMAND · 08-03-2017, 08:53 AM

Going to tackle RTAB's this evening and realized I have no info on proper ft/lbs. for the rear trailing arm bolts. I believe these are M12 bolts and collar nuts, one in the wheel carrier and one in the subframe.

Anyone have specs for these bolts or own the bentley manual and can do me a solid by looking it up?????

Searched and no DIY on here or E90post so if I can get the info Ill be glad to rehash it here for others with a DIY.

If nobody has the info Im thinking 70-80 ft/lbs.??????

Any help appreciated

So I don't make a typo and create a problem for you, here's a pic from Bentley.
I'd make sure your nuts and bolts are grade 10 if that is what RealOEM shows.
