Grease fittings on XJ

They just unscrew and new ones go in. I usually take one of the old zerk fittings in with me when looking for a new one.

You say you have two that have failed? That is 'very' unusual. I have one lower ball joint in my Cherokee with a 'failed' zerk fitting and I put in another. I still cannot pump grease into that joint, so I believe the whole joint has failed, not just the zerk fitting....

failed as in what?? broke off or won't allow grease to be pumped in?

Snow...

When I pump the one the grease won't even go in. The whole joint is dry which leads me to beleive that it doesn't have grease. On the other as soon as I pump it the grease pours back out. I've only done this once or twive before to a trailer and it always went in nice and easy. Maybe I just don't know what I'm doing. I have noticed that there has been grease on my rims where one of the fittings would drip.

Will Honea did pass the time by typing:

Or you use a 15,000psi lube gun and just blow the little ball across the garage. >_<

(followed by a real impressive stream of grease)

Are the grunts that tall or is the doc that short?

Last night I replaced 4 of the 5 fittings I could find in the front end. One was missing the ball and the other three were seized. The last one was missing the ball but I couldn't remove it. It seems to be seized in the bottom of the joint, the 'disc'(?) that it fits into is spinning in place. Any ideas on how I could hold the disc in place to remove the fitting or is this a sign of another problem.

Thanks Mort
