Purge once a year ( this is NOT a JEEP Rule, use common sense ) unless you ford streams or do deep soupy mud....
Purging is nothing more than forcing out the old wear particles and any mud or water that may have collected inside the joints.
The rubber seals are only stuck on, they have a small lip that grips the joint, pump grease until it comes out clean around the seals.
Then wipe off the excess and push the seal back into place.... Sometimes seals can get old and hard, and they will crack or break apart....Replace the joint ,or if your like me, I save every damned part I take off unless it's destroyed completely, so I may have a "spare" seal...
Ball Joints are a little different, you can still Purge em just watch for the bleed hole, some have em, some don't, the ones that don't becarefull not to rupture the seal. Some the grease comes out around the stud, kind of a pain to clean em up.
These should also be greased with the weight OFF the joint...Jack it up and block the frame, let the susp. hang... Work SAFE !!
Tie Rod Ends ..Same way, the seal will lift and grease goes all over...
Off hand I do not know what JEEP specs for grease.... I like to use Heavy Duty Truck grease ( #2 ? ) But i don't ford streams and I don't mud hole... For those who do, I think I would load the grease gun with a good Boat Trailer Wheel Bearing Grease (green/blue ) That would give you a lot more protection from water wash out....Just my Opinion.
Have fun... "BH"
