Simply not true. The design has been in production since 1984. If it had a fundamental problem, a) it wouldn't have been popular enough to sell 4 million units in Jeep Cherokees alone, and b) it would never have been enlarged and adapted to the Ram. "Wobble" is always the result of either worn or loose parts or a severe alignment error. ALWAYS.
It was more the requirement to add side impact beams, meet front and rear impact requirements, and things like that.
Whole different animal- thats the FSJ (Gladiator/Wagoneer) platform, not the XJ Cherokee I was talking about. I should have said 'XJ' specifically. The FSJ platform was probably the best SUV ever, which is why Wagoneers still sell for $20k to $30k. Every time I drive one of those I walk away shaking my head saying 'this simply CAN'T have solid axles and leaf springs at all 4 corners, it just drives too damn well, is way too comfortable, and WAY too quiet to be so good offroad." My wife even stops to look at really nice Wagoneers. It would be one of my dream vehicles with a new Hemi or a Magnum 5.9 dropped in place of the old carbureted AMC 360. Not that the AMC 360 was bad in any particular way other than being a bit heavy for its output, but you can't argue the superiority of EFI for offroading.
