Nope, they are a sealed case, but if you put waterproof grease on them, it will make them last longer. Moisture is what kills the seal on them. Every one I have changed failed because rust formed near the seal, and the grease leaked out.

 

Finally got the passenger side out. time to install the new ones. Drivers side is all put back together. Day 3 of the ball joint replacement process.

 

Well, that was fun. Time to wear them in. Thanks for all the feedback!

 

how'd you get the fat part out without a press ?
