Permanent fix for driveline slop?

[Eli]

My 120 has 123k miles or so. It has pretty bad slop in the driveline. Lubing the slip joints made it go away for a week or so, but now it's back and worse.

Anybody know a good permanent fix? Perhaps use a heavy grease in the slip joints that won't come out as easy? Or replace the driveshafts? What's a good source for driveshafts?

The driveshafts can be rebuilt with new U-joints, but first you need to confirm they are the problem. Could be U-joints, slip joints, could be issues with the transfer case or diffs, etc.

It's worth the effort to remove it and take it to a driveline shop so they can replace any bad U-joints, balance the assembly and check for runout. The shops, generally, will only use decent parts so they don't have to do it twice.
