I looked with horror at the final drive thread about splines that had destroyed themselves, so I went to Shop Talk to look how to service the drive assembly. I am abit confused about using a moly grease as well as another grease as well to lube the spline assembly. Is there a combination grease or does 1 go in first and then the other on top of the first? Moly(Guard Dog) and Lucas grease.
You can use Guard Dog Moly paste, or the Lucas grease or Belray Waterproof. I like to burnish a little moly paste into freshly cleaned metal (just a tiny bit since the Moly actually goes into the pores of the metal. THen slather a healthy coating of a good heavy duty waterproof grease over the top of that.
Many just use the water proof grease or just use the guard dog. I find the moly grease dries out more than the waterproof stuff.
Bottom line the grease itself isint as important as it staying in there. Water will wash out a weak grease.
re-doing it every 10K miles or so seems to be the best insurance.
Hope that helps
