Drive (prop) shaft repair

I have continued the process of bringing the M5 to a pristine condition and changed the 3 differential bushings, 2 transmission mountings, CV joint, guibo and centre bearing among other things.

Since I have some more money to spare - and I hear a metal clink when driving slowly with open window when braking/accelerating or changing gears - I am thing the cross joint is next.

A new one is close to 1000 euros.
There few second hand one in the US for around 300 $, but the postage will be probably the same.

From what I gather and from the discussion (over the phone) with a specialized kardan service, they change the cross-joint with a new one. I was given few options by them to exchange the cross with a Chinese, Turkish or Polish cross-joints with prices ascending in that order.

something like this:

BMW E39 520 d 520 523 525 d td tds 528 530 d 530 535 540 M5 PROPSHAFT JOINT | eBay


I would have gladly go with the higher option, but they refuse to give warranty on that (the argument being "I know you BMW folks and the way you drive" BS, even though he would give warranty on a thousand Nm truck rebuilt shaft, but anyway...).

Any way my question is:

Who makes the genuine cross-joints for BMW shafts?
What is the replacement of a similar / better quality?

I'd go in to any driveline shop and have them measure and replace that u-joint. $30 seems about right. 1000 Euros seems insane.

Verify that it is the center u-joint. It may be the CV joint on the input of the diff.
See this thread https://www.m5board.com/vbulletin/e39...nd-rattle.html

If it is the u-joint, I wouldn't try replacing that myself. Find a used driveshaft or search for rebuilt ones. We have a couple options on this side of the pond that come to less than $500 shipped for a rebuilt complete driveshaft.

I have replaced the CV joint already with a new BMW one, but I will have a look again.

I did find a couple of good driveshafts in the US ebay but none in UK and German ebays. Postage to Europe will kill the deal.

I will take it to a specialized service if I go the rebuild route, but so far I don't like their approach (refusal to give warranty on a BMW M5)
