Hi,

How do you tell if Lobro driveshaft joints are still ok?

Cheers

If they dont give you Knock KnocK jokes when in use. Other than that the clues are rubber boots ok and what condition the grease is in ( Is it contaminated or not) other than that its lucky dip.

Cheers. They're not fitted to the car, they're on the bench!

Should there be any slack in them at all if I hold one end and try to rotate the other?

Cheers

Why don't you strip them and check them that way? I did this a couple of weeks ago, its simple really. There are 6 ball bearings, the outer and inner case and a bearing locator thing. Just make sure you mark them up and put them back the right way round if not it will be a locked joint. I drilled a tiny dimple in the outer and inner case so I knew where to align them when rebuilding.
