Go with Moog ball joints. Quality stuff, and both uppper and lower are greasable. (a small 90 degree zirc has just enough clearance on the upper to remain in place) You'll pay the most for Mopar replacements but wind up with the same questionable items you have now.
I would replace all 4 and also do the steering U-joints while in there, as the stub axles have to come out to get the knuckles off. You may find, as I did that some of the cross ends have started to brinell.
As a matter of fact I did have the oft posted nightmare of removing the one-piece hub/rotors on my 95. That is the most difficult part of the job IMO. With luck yours will easily separate. Otherwise you will need a LARGE puller. Using longer 14mm bolts in place of the attachment pieces for the hub in the back to pound on with a 3 lb hammer also can get it off. A heathy bath of your favorite rust buster(liquid wrench, PB, Kroil) on the big axle nut, the 4 bolts that hold the hub to the knuckle and the ball joint nuts, about a day before starting the job helps. A decent impact wrench removes the axle nut.
Be careful sliding the stub axles out and cover the splines with bearing grease before re-installing helps avoid gooning the axle seals.
Otherwise it's straightforward. Good luck
