X3 Driveshaft replacement

[6MTZHPX3]

Hi all,


My X3 3.0i manual has had a vibration from the rear for a while, but has recently begun to vibrate a lot more than usual, signifying that something needs to be replaced. It begins at about 50 mph and gets very significant at 70. I am looking at replacing the driveshaft due to the worn non-serviceable U-joints at the differential end.


There are a few options, but I am looking at the USA Standard Gear and Trakmotive from RockAuto and Driveshaft Specialists of San Antonio, their Type 1 driveshaft for BMW.


Which do X3 owners have better luck with? Will also be repairing the guibo, preferably with a SGF manufactured one as reccomended by Driveshaft Specialists. Does the Febi or BMW brand use this manufacturer?


I am a relatively experienced DIY mechanic, and recently did the entire cooling system refresh on my X3, as well as replacing shocks and struts and valve covers on other cars, and tracking down a few electrical gremlins on my X3. Any tips for the driveshaft replacement?


Thanks.

Vibration is usually a sign of the center bearing and/or Guibo rubber deteriorating, are you sure the u-joints are worn?

The above is very true...I've stock piled a couple of rear driveshafts from the wrecker in case of quick replacement needed.
Not a hard job but an intense job...
Many examples on YouTube.
After doing the replacement a couple of times, your somewhat of a pro.
If your lucky you've got a shop in town (like I did) that will take the time and do the welding. The shop particularly worked on the drive shafts of large trucks.
Made my little e83 look like a hotdog .
