Driveshaft CV joint, just double checking #15 on this diagram is not needed, for non M cars that have the #20 cap cover thing. #21 is needed of course

The picture of that pn# looks correct to me.

Thank you.

Saw this on ebay and look good too:

Can Anyone confirm the PN for the ground cable from the engine to the chassis? 12421737755?

Ok diff mount questions.

Are the rear mount torx bolts (inside the cover) one time use only or can these be reused?
Is there supposed to be a washer between the mount and where it touches the subframe?
Anyone have an objection to using a different style of bolt of the same size and grade if I can't fit a torx socket on there? I have CMP subframe mounts

I've reused all my bolts without issue - however, I'm pretty sure they're all torque-to-yield and are considered single-use.

They actually don't show as TTY/"always replace" in the torque spec doc or TIS, as far as I could tell.

I see no issue with switching to a hex head if it's the same grade and length. Torx head is just for reduced chance of stripping. Not a bad idea tbh. No washer between the subframe and mount... https://www.realoem.com/bmw/enUS/sho...diagId=33_1076 . just for the mounting bolts.

I have cmp bushings, and initially had a tough time with the bolts as well. You need a lower profile ratchet and torque wrench. Check out my posts in this thread: https://nam3forum.com/forums/forum/m...ff-bolts/page4
