I also own a '90 XJ and I can't believe the difference in the rides. I had a few spine surgeries so love the height in my Jeeps (no bending to get in). I gave my KJ to my wife because the ride is so stiff that it hurts my back to ride in it. It only has 15,000 miles on it. My Cherokee on the other hand is a dream to go everywhere in. Does anyone else think that the Liberty's ride is STIFF? One last thing, the KJ rides like a dream on rough roads. Is this because of the Trail Rated Suspension? (Aeh)
