Ok, you confirmed it was true DW. I asked because it's very common for some to think DW is another way of describing what may just be a moder-to-bad shimmy.
And I was also just letting you know that replacing the tires still left your Jeep vulnerable for DW to happen again from just another out-of-balance or bad tire. After FIXING my Death Wobble years ago, I've had periodic out of balance and out-of-round wheels & tires with none of them causing DW. I can see how some would think replacing their tires "cured" their DW but even with the tires 'triggering' the DW event, the suspension should still be able to cope with the problem and dampen it out without allowing it to develop into full-blown DW.
DW also happens with Fords and Dodges that share a similar front-end to the TJ, as well as motorcycles and bicycles. It's a geometric issue with undesireable harmonics building upon each other that has so far, had an elusive answer to a permanent fix where tires don't have to be replaced just because one has a problem.
