-jack up front of kj
-remove front tires
-disconnect upper balljoint/tie rod ball joint/lower balljoint
-support the hub by wire on the upper arm, dont let the brake line hold it
-tap all the ball joints out with a hammer
-use a needle head grease injectror adapter and grease gun
-insert needle between the shaft and the rubber boot being careful to push slowly and not hurt the boot
-once in inject an ample amount of grease in to the boot
-(one thing that helped me get my nuts back on my ball joints was to take a wire brush to the threads of the ball joint, clean them up real good)
-jack up lower control arm so you can attach upper ball joint
-reconnect all the ball joints and torque them down good
-put tire back on and drive with a little more confidence

Yeah, been doing something like that for years; you just have to keep doing it... Too bad there is no way you can place a small seal there when you are done, so when you put it back together, it doesn't all come back out so quickly. When I do this, I use a Plastic syringe, like the ones used for ink refills for printers. You don't need a lot of grease, that's fore sure, and it works well. If you had the patients, you could use a REAL syringe and a LARGE needle...

ya the one i got is made for stuff like this, just a needle attached to a gun. found all the stuff at fleet farm. i had no problem with them leaking back out. you will find out right away if you have any leaks and tears.

Ive tried to do that and had some a very hard time. Ive got a spare upper A-arm laying around and it was really easy to grease it up. I just took the boot out and cleaned it all up then used the needle once it was back on. While there on the Jeep its pretty hard though.

The tie-rod ends are really easy to pump grease into though. I filled those up not long ago.
