drive shaft u-joints maintenance

Recommended Posts

Hello, my drive shafts u-joints on my robin hood 2b failed after 3k kilometers after rebuilding them (rebuild was done at the end of the March). They said, that they wasn't lubricated. I did not know that it was necessary to lubricate them. How often should I do it? They said once a year, but mine failed after 6 months. Or is it possible that I have too much power for this driveshaft? Robin hood 2b, Zetec 170HP 210Nm

driveshaft CV joints should be packed with plenty of molybdenum disulphide grease. As long as the boot does not fail and the grease leak out, they should not require further maintenance.

I am going to go out on a limb and suggest there's probably a varying degree of quality in terms of UJs and propshafts. Depends where the propshaft came from, but maybe it was made "to a budget" (not saying by you, just whoever supplied it)? Or it may be you was just unlucky with this one (it can happen, you just get a "bad one")... :( annoying though. I have a spare prop from Robin Hood somewhere, not sure it's right length, but given your location it's hardly an easy "pop over and collect" :)

it's not necessary. I've picked it up repaired at the local cardan specialist today. Tomorrow I am going to install it, so no problem.  They did all the work now and also 6 months ago. But this time they installed different type of the U joints. Or I think that because the nipple for adding grease is completely different.

All I wanted to know if anyone had same problems, and also to know how often should I grease the u-joints and what type of grease should I use.

In all my years as a technician I’ve never bought a prop shaft that came packed with grease UNLESS the supplier stated so. That’s new or rebuilt maybe the supplier forgot to tell you it needed Doing before fitting.
