Part # 7224400
Final Drive Pinion Tool

Got this nicely made socket to install a spanky brand new retainer nut. The socket teeth wouldn't fit in the nut slots (teeth too wide for slots, didnt measure, looked like a few .001. , same fit all the way around, any orientation ) Dunno if BMW or socket folks got their maths out of step I opted to file the nut slots wider as the easier task to do accurately , not too difficult but still, shouldn't have to with new + new parts. If you are starting with a removal and find this issue, obviously you'd mod the socket. Doesn't take too much and do evenly all around, to keep as much contact interface as possible . Keep em square to avoid slip out Will learn someday ( next time I do a drive) if I modified the right part.... could maybe the socket teeth width was the problem. Couldnt try socket on old nut since I pretty much hogged that one out with my previous makeshift tool botching a sticky nut, was lucky to extract it ! So cant say I am unhappy with purchase. Job done. Price of admission. Glad B2V supplied it a great mod would be find a way to lock the socket up against the nut (a ring or collar or bracket , anchored around the socket to the studs on the drive house comes to mind) to prevent socket slip out from nut on a difficult starting torque. Dont forget to heat the drive housing to prevent a No Good Rotten Day. And JUST SAY NO to setting thread sealers, huge nut w/ fine thread an really lock in place with any adhesive action... If the socket is " sloppy' in the nut , find a way to keep the socket securely centered in the bore, to prevent sideways slip out, that was the death of my old tool.

Excellent tool , a must to do this job.

Nicely made. The sales picture should show that it takes 1/2 inch socket drive. It would help to have 66mm collar to steady it in housing. Does the job.
