92 yj 4.0 5spd, procomp coil conversion, 33" tires. I have very violent shake that rumbles and slams the jeep at around 35-40 mph. My zj had dw and I fixed it with new front control arm bushings. I am familiar with the death wobble. What I am getting on the yj is a very similar bucking, but my steering wheel does not shimmy like the zj did. It is so violent it shakes everything until I stop. The old jeep would only buck at a certain speed, but if you accelerated or slowed 5 mph it stopped.... The wrangler just heaves violently until I stop.
I thought maybe it was a bad ujoint (I do not have a cye kit yet) so I pulled the rear driveshaft out and drove in front wheel drive. Same issue. Violent shaking and bouncing. I also jacked up rear and checked the tires for wobble by spinning by hand. No issues. I took tire completely off and did a visual on everything. No missing bolts or broken parts. Reinstalled tires and took test drive. Same issues.
Anyone have the coil conversion and ran into this problem. Like I said, it's very violent like death wobble, but I think its in the rear because my steering doesnt shimmy when it goes off.
