Is there any grase in cv joints?

Question

Do they come pre lubricated?

for broken ones what type of grease to use?

Answer 1

yes they come pre lubricated if you buy a one that is ready to go. It is black in color and very greasy and sticky. It is a high temp moly grease and sold in all autoparts stores.

Answer 2

Yes- for the most models it is a black moly stuff. It can be injected into the cv joint with an 8'' long copper line soldered on to a grease zert, which is pushed along the axel under the rubber boot, without damaging the boot. Then a new clamp (usually a nylon wire tie)

Answer 3

Yes there is grease and if you buy a CV Shaft Assembly it is all ready to bolt in.

Dude, slow down.  Your brain is going to melt if you keep asking questions at this pace :)

Answer 4

what is grase, i no understand

Answer 5

You do not re-grease broken cv joints you replace them.  If you are talking about the rubber boot being broken, it can be replaced and new grease put in, but only if it has just cracked.  If it has been split for any length of time there is grit in the joint, and it is ruined.

Usually the best is to have the axle replaced, it comes with 2 new sealed joints.  For my car, one cv joint replaced would have been about $150.  The whole axle, with 2 new joints, boots, the works, installed, with warranty, was $200
