I gave it an inspection and re-grease last winter and no wear was showing. I had a bit of an issue of getting grease to go to each of the individual bearing cups - grease will follow the path of least resistance - but eventually everything took grease as needed. These are on and off road miles that I am putting on this unit. I have heard about the spider issues but so far this hasn't been my experience. When the time comes, I'll just upgrade the spiders/bearings to the latest and greatest. I'm very pleased with my purchase.

I had a few broken ones.(all bearing failure) Those were all from the first series which had a smaller bearing size than the stock BMW shaft.

Don't wait to long with the maintenance. When a bearing is broken or worn the outside of the bearing will start to spin in the shaft it self. Than its loose in the shaft and will wear the shaft even faster. I had to replace a shaft because of this...

I figure I'm on borrowed time in that I've got nearly 130,000 miles on the original........yes the original drive line.

Match that....huh....huh! Anybody......Anybody!

Original shaft went 252k kms in my '92 GSPD.

You win Lornce - no one is going to touch you mileage wise. Now please explain all the major wear on the yoke surfaces. Something must have let go.

On the 2, I trashed, @ 20,000 and 64,000 miles . That's what they look like about 150-200 miles after you first sence somethings not right . The cups have cracked, rollers have broken . In one of mine 175 miles, 3 rollers were spit out of the blown end of the cup . The wear is the reality of the way they fail, and quickly . They really look ugly when pushed beyond a few hundred miles . That in my and friends expierences .

Regarding the re-buildable shafts: can the early series be upgraded to the later joints?

I hope the answer to that is yes.

Yes they can.
I just had two of them re-build with the new type bearings.

Where are the bearings purchased from? I'm guessing with these improved bearings, we now have a bullet-proof unit, which is now hopefully worry free? If these are available for online purchase, a link to the site would be very much appreciated.

Mine came from The Boxertoko in the Netherlands.
They were the first ones to be re-build with the new type bearings.
Could be that the website is not up to date yet.

19mmX48mm???? Or I should say same size as the OEMs R100GS which btw is same size as every BMW driveshaft all the way to now.

If that size looks like they are also available from other suppliers. You guys can check the Elbe 106 series, the "later" GS guys are using them for DIY rebuilds. Untested yet the DIY but we are digging up the info right now for someone in England looking at rebuilding a K driveshaft.

Prutser - I just followed your link and it came up with the greasable replacements for the original OEM BMW driveshaft (p/n 2618850) and so I am starting to wonder about whether or not everyone is on the same page here. I'm talking about the Taiwanese replacment unit that I bought a few years ago (Illustrated above). Lornce gave us nice shiny pics of his beaten to death original shaft and I'm thinking that you might be talking about this variety of shaft - not the Taiwanese one. If anyone else is having problems keeping all this straight, please chime in.

The online site for Motorworks BMW describes the Taiwanese shaft as being equipped with larger u-joints than the OEM variety and are therefore harder to slip into the swingarm during installation. Are these 'larger' u-joints failing and being re-designed? As I say, mine is providing good service and I am curious if these shafts are being re-fitted with new bits to provide trouble free service.

I'm talking about the shaft thats on your picture. They didn't have bigger u-joints than the original shafts. They had smaller ones. The new version has bigger size u-joints.
The outside diam of the old and new bearings didn't change the inside did.
The first series of those shafts had a problem with the size. They would not go through the swing arm because they were just to thick. A few spins af an angle grinder can fix that

I didn't measure the size of the u-joint bearings my self but this info came from Mat from the boxertoko.
Now they should have the same size as the original bmw shaft.
