Upper Control Arm Part Help

evanse · 07-29-2018, 10:17 AM

Hi,

I was starting the install of ACS springs to my 2015 535i xDrive and I just couldn't get the upper control arm off of the knuckle pin by myself, so I went to put it back together. I pulled a torque from the forum @ 122 ft/lbs. Well that snapped the bolt. Probably because it is a one time use bolt, or that torque is wrong. Either way I need a part # and I can't seem to find it anywhere.

Has anyone replaced that bolt? Do you have a part number? And is that torque correct? Any help would be appreciated.

Also - I do have the m-package, but from what I've read, because it is an xDrive it is not any different than the non-m-package. Thanks

I cant find the correct torque now, but 122 ft lb is way too much.

The bolt is a M10x1.5 10.9 grade with Torx head, I expect the torque spec to be around 50 ft lb.

The torque spec for that bolt is 56nm (41 ft. lbs)

The nut should also be replaced any time it is taken loose.
