New (used) driveshaft on it's way/Questions

[lhead]

Because I had a front u joint failure last week on the K1100RS at 80k, I've sourced a driveshaft from an RS with 30k. It's being shipped to me. A new shaft from BMW at $700 plus wasn't an option.
Questions:

* Has anyone found a source or procedure for removing the "lube for life" staked in place u joints and replacing them? I know that a company called Rockford makes u joints that are designed to replace staked u joints but I don't know if they offer a part that's the right size. All the applications they list on their site are automobile based.

* Does anyone know of a way to just remove and disassemble the u joint for cleaning/inspection/regreasing?

What I don't want is to get the new driveshaft in and have this happen again in a month.

Thanks,
Charlie

There are vague rumors about people replacing U joints but nothing concrete. I think Bruno's
in Canada would replace them for big $$. The problem is many are in crooked from the factory
and so require machining to correct them before a new one can be installed. I bought a 9K
driveshaft on EBay and the U joint on it is bad so I'm looking for the same. I might try a
automotive driveline specialist as they sometimes replace swagged in U joints.

I guess German engineering/QC isn't what it used to be.

Bruno is German. His quality is fantastic. Rebuilding the whole lot on a k75 was about ~800 dollars, including a new FD bearing, U joint, Pinion gear splines, Shaft Splines (All made to aircraft tolerance with 65 rWc hardness) and about an inch of extra spline meat.

I wonder how much to do just a U joint?

Just email him. should be pretty reasonable. or take it to a car machine shop and see what they can do.
