Hey guys i have been having u-joint failures in my rear drive shaft due to the slip yoke being seized, after finally pulling the yoke apart a blue coating has been stripped off and the yoke has some play. I have done some searching and it looks like the blue coating is there to fill the gap between the male and female splines and provide lubrication. My question is where can i buy this compound to reapply it? Or do I have to buy a new yoke? Thanks.

 

When you installed your SYE for the 6 1/2" lift did you shim the rear differential also? If not that could be the cause of all the u-joint failures.

 

I am not sure, the lift and sye were installed before I bought the jeep, the previous owner said all work was done at a shop. Once the yoke is moving freely I will try my luck I just have to find the correct compound they use on the splines
