MK1 driveshaft

Noticed tonight I have play in the outer UJs on my MK1 driveshafts,are these easy enough to replace or is it better to get replacements,if so who stocks them,CW seems to not supply complete units?
The outer UJ clicks when twisted by hand back and forth.

Unless there is a problem with the hub, ie any play or bearing roughness, I would just replace the UJ. It's the cheaper option by far and a used driveshaft may need a replacement UJ or in extreme cases there may he excessive wear in the splines.
Have you eliminated whether there is any play in the inner UJ or in the splines?

Hi
The inner UJ and slines seem fine,all greased and no rear end twitch,its just the outer ones..
are these easy enough to change or best left to a garage?

Hi,
replacing the uj's is straightforward with basic tools, the Haynes manual covers the repair. You need to remove the outer shaft and press out the uj cups in a vice and if you can- make sure the replacement uj's have a grease nipple fitting. When the shaft is out it's much easier to feel for any excess play or roughness in the joint.
Good luck with the job.
Mike.

As Mike says it is job you can easily do yourself, but a third pair of hands can help in supporting the shaft. A vice, circlip pliers and selection of suitable sized sockets are all you need. When you have pressed the old cups and UJ out, make sure there are no burrs on the edge of the yoke; if so, use a small round file to remove them. Make sure none of the small needle bearings fall out of the new cup whilst fitting the opposing cup into the yoke onto the new UJ - a light smear of LM type grease can help hold them in place. Once the new circlips are back in place, a copper mallet or soft faced mallet can be used to tap the new UJ and cups back against the circlips to make sure they are moving without binding. Before refitting the driveshaft, make sure the joint is free moving in all directions - if not, a light tap on the UJ towards the bearing cups with the copper mallet should move the offending cup slightly so that any tight spot goes.
