Title: inner cv query
Post by: oakgreengolf on 15 December 2015, 18:34

I have a leak on the drivers side cv. On closer inspection it appears the cv boot is fine and one of the bolts was loose where it  meets the gearbox. I've removed the drive shaft and am uncertain where I replace the grease, do I need to remove the boot or is the grease applied where the cv joins the box. Thanks in advance.

Is it possible its the actual driveshaft seal into the gearbox that is leaking?

Definitely cv grease that has come out where the nuts were loose. Just not sure on the easiest method of getting it back in.

yes the drive shaft bolts clamp the cover that seals the grease within the joint
-if you tighten the bolts up they may just come loose again due to grease contamination.

the fix is to undo the drive shaft, degrease the cup and especially the threads that the bolts go into.
I would have a really good look at the CV boots, if you can find any sign of wear and as your inner bolts are loose, you are only the hub nut/bolt away from removing the complete drive shaft allowing you to service the entire drive shaft with new boots & grease
