06 325 CIC Prop shaft U joint

[jimdanforth]

Pulled driveshaft for Guibo and CSB and found the U joint pretty shot. It appears it is not serviceable. Are there any reasonable options? I'm only seeing used that I'm not real comfortable trusting, and complete shafts. IS the half shaft not available? Also, is the shaft unique for the convertible? Cantt see why it would be other than cost me more money

It is indeed serviceable, just not by the average user. Any driveline shop worth their paycheck can rebuild it. Saying it's "non-serviceable" is one of the great lies along with "lifetime transmission fluid"

The u-joints are staked in, so they are a pain to remove. Not something you'll be doing in your garage. A local driveline fabricator shop charged me $350 to rebuild mine.

The rebuild included: center support bearing, front u-joint, and balancing the shaft. They didn't mess with the back CV joint.

I just ordered one from Driveshaft Specialist in Texas for an 2005 X3 3.0. After a ton of research this is the place to go. All the other sellers are Chinese parts and almost the same price. I'll let everybody know how this goes once I have the new driveshaft.

I had a similar problem with a same year X3 earlier this year. My rear u-joint was clunking around. I ordered a cheap driveshaft from Rock Auto. A strange harmonic resonance started at about 25 mph that wasn't there with the old driveshaft. I got a replacement under warranty and the made a similar, but slightly different noise. Again back for a refund (minus the shipping both directions for 2 shafts.) Luckily my local pick-n-pull got a X3 right when the 2nd shaft was pulled. So I got the rear shaft from that X3, and it was clearly recently replaced, but wasn't a BMW shaft either (no ID marks, so I can't tell you where it came from.) Installed that shaft and the noise is gone, along with the clunking that was the original problem.
