So I noticed a some slop in the rear of my X5 when driving over small bumps, potholes etc.. Low and behold the rear passenger strut is completely dangling!

Heres drivers side for comparison

Im not sure if the bolt snapped, or rattled out or what but what I do know is I referred to realoem.com specifically http://www.realoem.com/bmw/enUS/show...diagId=33_1029 to try and track down the bolt and locking nut.. I ordered 2 each of #21 Hex bolt (33321092870) & #22 Self-locking collar nut (33326760383) to go ahead and replace both sides..

To my dismay once the part arrived its a millimeter or 2 too thick to fit!
I went back into my Bentley manual to cross reference and this diagram is the same as realoem

But looking at this diagram
Im starting to wonder if I ordered the lower bolt pictured on the swing arm assembly instead of the bolt and nut labeled #2 and #3 in assembly "A" where the strut attaches.

Now referring back to realoem for part numbers I cant figure out exactly where this assembly "A" is located :/
Im not sure if Im looking at it upside down or backwards or what... I thought I was so smart there for a minute but now Im lost..

If anyone has had this problem or can read these diagrams better or has any idea what bolt and nut I need I will be forever greatful!!!

Thanks in advance, Phil
