g_frey Posted September 17, 2009 Share Posted September 17, 2009 Oh Boy what fun! My clunk, clunk, clunk problem with the power off on my R1150RT is the U joint just in front of the final drive. I opened it up and little pieces of metal fell out. Checking parts lists I believe this is considered part of the drive shaft and not available separately? Well at $830.18 I am not a happy camper. I cannot rebuild the joint it is very bad with pieces missing off both parts. I am surprized that it did not make more noise since there was a good 1/2 inch of play in it. Miracle time? Can anyone tell me a cheaper way out of this? Surely someone will sell just the parts I need? My 73 Ford pickup with 289,000 miles and grease zerks cost $70 for one u joint kit in its life??? Plus did I miss a maintenence item here??? 70,000+ miles Link to comment
Jerry Duke Posted September 18, 2009 Share Posted September 18, 2009 Check with Beemerboneyard.com and try Ebay. Might find somebody with one through the Marketplace on IBMWR.ORG Link to comment
T__ Posted September 18, 2009 Share Posted September 18, 2009 g_frey how does the shaft & end bearing cap loops look? If those are not oblong,, distorted,, or banged up you can probably find the proper sized U-joint & re-build the shaft.. Or send it to a shaft specialist for them to put a new joint in it.. If the shaft or end bearing cap loops are torn up then it is probably the end of that shaft.. Check Flea Bay as I have seen shafts on there from time to time.. Twisty Link to comment
g_frey Posted September 18, 2009 Author Share Posted September 18, 2009 Will try both, Thanks Link to comment
g_frey Posted September 18, 2009 Author Share Posted September 18, 2009 They are chipped, hammered, blue, in short worthless except as examples. The splines are excellant oddly enough. Thanks for the info though. Link to comment
g_frey Posted September 18, 2009 Author Share Posted September 18, 2009 Checked ebay found one with a bid of $75 but 55,000 miles. If I am going to do it I might as well get a lower mileage one. Thanks for all the help. In my Clymers book it mentions just replacing the u-joint so I am pursuing that angle. The parts look like production parts with no dynamic balancing marks so they should be available I hope. In any case if BMW claims dynamic balancing is needed I would remind them that except for the noise I did not notice any vibration. Link to comment
Mark K Posted September 18, 2009 Share Posted September 18, 2009 BTDT........ mine was closer to 80,000. Used shafts can be found without too much trouble. I saw I couple decent ones with 30k on them for $300-$400. Since the used ones may have been 'halfway gone' at that mileage, I bought a new one. You can get a discount through Chicago BMW. I think yours was just under $700 plus the clips. Link to comment
g_frey Posted September 18, 2009 Author Share Posted September 18, 2009 Well I tried to find the u-joint without the drive shaft. 17 splines to 20 splines plus a "B" with a Diamond around it were not much to go on. There was also a "30/03" stamped in. After cruising various European and American web sites I ended up with nothing. BMW of course knows nothing or at least will not reply. I searched Bosch real hard with no result. It looks like it is bite the bullet time. These addictions are so expensive! I think a grease zerk would have prevented this problem. Link to comment
