    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Drive shaft u-joints

Hi all, just bought an 83 GS1100GK that needs a little work. It needs new u-joints in the drive shaft, the previous owner said that you have to replace the entire shaft. Does anyone know if this is correct or can just the u-joints be replaced ( I know that they are pressed in)? Also how hard is it replacing the u-joints or the shaft (which ever it has to be)? I'm a pretty good wrench, but not that familiar with shaft drives on bikes. :D
 
Just wait a little while Our resident GK expert Nick D. will surely have the answer.

I must plead ignorance on this issue. I've never had a driveshaft/u-joint unit fail on me in almost 17 years of GS shaftie ownership. My guess is that the entire unit should be replaced.

Wish I could be more helpful.

By the way, I have a driveshaft/u-joint unit for sale, off a 1980 GS850GT. I don't know if it will fit your GK, but it's possible. I do know the unit off a 1982, 83, or 84 GS850G or GS1100G (or GK) will fit it.

I would say they are probably repairable if they are pressed in. If it is, should be the same as on hydronic pumps (excuse my HVAC background). Hard and long work to get the thing dismantled for bearings and/or sleeves replacement, unless you have a good u-joint extractor for these. Better leave it to a mechanical shop, and not necessarily a bike shop. Then you need to find the same size replacement parts you need. I would suggest to go to a bearing place for help on sizing it all. Good luck and let us know how it goes!
