CV Maintenance

Post by Booga-dune-poon » Mon Jan 03, 2011 2:07 pm

So I'm sitting around on vacation between Christmas and New Years thinking about my next sand dune trip and decide it's time to pull the buggie out and spend some quality time with her. As I'm running through the check list looking for the next "weak link" I pause to look at my CV joints. They look good on the outside. But what about the inside?

My buggie is about 2+ years old with about 6 or 7 trips. The German 930 CV's were installed new when I built the car. Last season I pulled the rubber boots back and shot some extra grease in there. I've got the time to do this and it's probably past due so I take a run to the car parts and hardware stores to get supplies (tube of moly grease and a can of kerosene).

Great reference information:

Pull the bolts, CV's with axels and wash off the old grease.

Inspect the ball bearings, cages and grooves for pits, scratches, etc.

Everything checked out OK so it's time to fill up all the nooks and cranies.

1 down, three to go.

The bad news is that my 2 year old grease had started to harden. The good news is that I caught it in time. I did not detect any defects during a visual inspection of the CV's or the rubber boots. Now I've got a little peace of mind, at least I don't have to worry about my CV's for another year or two.

Bottom line: Cost = $15.00 for 1 tube of moly grease and a gallon of kerosene to wash everything up with. Time = 1 day (hey, I work leasurely during my vacation)
