Well, son #2 was complaining about some clunking on minimum-radius turns at low speed - at 68kmi, the KJ still has the oem balljoints, bushings, half-shafts, etc, on a 2" lift, so I checked all for loose, worn, etc - nothing found at the time, all seemed copasetic - however, with Moog K3199's in posession and horror stories of oem lbj's cratering in the driveway in mind, I decided to take matters in hand and do the deed.
Surprise, surprise!: oem lbj's at 68kmi are just as tight as the day they rolled off the production line - takes a wrench to rotate the stud in it's socket, no finger-loose there - on the other hand, the ubj's, usually outlasting two lower replacements, were loose as gooses, both easily manipulated by finger\thumb - this is unusual, but could be caused by the mild 2" lift, the greater wheel offset and wider wheels, and the big Goodyear meats - so, in with the Moog K3199's, since they were sitting in the passenger-side foot-well, but what to do with those wimpy oem uppers?
Enter Jeepin' by Al, with a nice set of red Nascar-type fabricated uppers, replete with replaceable Moog larger-than-oem balljoints, factory rubber bushings, and at less than the DCJ list price for the stockers - don't like the red, but a can of rustoleum semi-gloss black will easily fix that (cleared that with ole Al, hisself).
So, for those whose maximum intense offroading experience consists of parking in the grass at family outings, no worries on the factory ball joints - there will be some unexplainable early failures, as with anything 'consumable', but you are not in dire need of the Moog upgrade, as has been previously noised about - just have any failed lbj replaced with the original spec item, and yer good to go - if, however, you weekly put the KJ in stressful conditions that even the design engineers did not allow for, such as rock-crawling and slope-groping, Moog K3199's and Al's is the way to go
Also, prolly should have a nice new set of ABS wheel sensors handy, as the oems are likely rusted in-place, and snap-off ever so easily -
