Kind of venting here, but also seeking information.

Last month I rebuilt the rear end of my 04 325ci for the second time during my ownership period. Once at 130k, now at 220k. Did the rear subframe bushings, upper and lower bushings and balljoints, diff bushings, swaybar links, etc. Ended up buying 2 new GKN halfshafts 'cuz I noticed mine had more play in them than I was happy with.

The passenger side installed w/o issue.

The driver side that was sent to me - the threads for the axle nut were too short and I was unable to get the axle nut on far enough to distort it. This axle may have worked fine, but back to the vendor it went. In speaking with the CS agent, he mentioned "they are probably all like that". So, I took the return and bought another axle from another trusted vendor. I put my old CV axle back on...


Fast forward to today, I pull the old axle out and am installing the new axle. Something isn't right. Upon further investigation, it appears there are significant differences between my axle and this one. It's going back on Monday.


Hoping 3rd time is the charm. Anyone know what axle they ended up sending me this time around?

Did you look up the rear axle part numbers on www.realoem.com?

Enter last 7 digits of VIN to pull up your chassis. I think there are two different kinds of real axles for these cars, maybe they sent the wrong one. In the pics above the axle shaft itself also looks thinner on the new axle.

Good eye re: the thinner shaft.

In doing more research, I believe they sent me an E30 axle. I'll have to check the garage tomorrow to see if the box was mislabeled. I did order the correct PN.

Anything is possible. Make note of the original axle shaft diameter as well for when you call CS again. I think that is part of differentiating the types of axles, and it may even be referenced under the part number in realoem.

I'd have to think a "mis-box". Unfortunately I've seen this more and more as of late. Even from the dealer.
My rule now is to open the box and carefully inspect before any work is performed.

The last one we had an issue with (E83 X3) took 2 tries from my WD and 2 from the dealer. Took a "parts specialist" at the warehouse in Nazareth Pa. a week to send the correct axle, owing to an issue at the supply side of the chain.
The incorrect ones were missing the reluctor wheel for the ABS/DSC sensor to read.

GKN 304740 sticker on box and also on the shaft. This GKN PN aligns to the the correct E46 fitment. So, GKN dropped the ball on this one.

So, I reached out to the vendor who confirmed that the part was indeed wrong. They checked the 1 other axle they had in stock and it seems like it's also mis-packed. Hoping to gamble with a 3rd trusted vendor next....
