As I joined the highway on my way home today, the steering started to oscillate. The steering wheel was shaking left/right at 60 MPH, in the same way as it would if you had a severely unbalanced wheel.
I slowed down to 40, it eased off, and eventually stopped. I accelerated again and it was gone.
I've read the relevant sticky, but can't figure out of this is death wobble or not.
So, is this death wobble, caused by the infamous 14mm bolt in 9/16th hole?
kJeeper10 is on the right track. My 08 was doing the same thing. 45 to 60 it would occasionally shake horribly, some times I would have to stop completely and other times just slow down to 35 and it would go away. I installed a new JKS trackbar, JKS steering damper bracket, trackbar relocation brackets, heavy duty stering damper, & changed as many 14mm bolt out as possible. I have been DW free for 6 months. My fix was about $550.00 Good luck man, It can drive you crazy.
Some say you you can have the beginnings of DW or its not DW unless coming to a complete stop. Not true IMO. You have the track bar, upper and lower control arms constraining the axle. Any one of these bad theres going to be problems. Bad Ca and track bar ... BIG problems.
I've never had full out DW surprisingly, my TF track bar adjustment sleeve lost torque. The jeep would shake hiring bigger bumps. Enough to realize something wasn't right. Sure enough my TB was loose causing the side to side shake.
I'm usually pretty good in scary situations, so no poop. But my wife did find it somewhat alarming.
Thanks everyone for your feedback. I'm going to check the track bar for play, and replace the bolts if I can find suitable replacements. I'll post back results.
It's difficult to check a track bar for play. It doesn't move easily. I installed JKS aftermarket bars and I must've sissy'd it because my axle was... 'swaying'... afterwards and it annoyed me. Not a wobble, but perhaps the beginning stages of DW. The track bar wouldn't move during inspection but finally I bit the bullet and unbolted and re-torqued it with all the 140lb man strength + breaker bar power I could muster. My 'swaying' is gone but since I'm not a strong guy I think I'll have to re-torque it now and then.

If you thought the Jeep was going to fall apart in the middle of the road resulting in full destruction of you and all vehicles near you if you did not stop fast, then you had death wobble. If it just oscillated like you had a slightly off balanced tire, then you have not experienced DEATH Wobble, yet.
I had DW on a Rubicon I rented in Moab. It only ceased when I came to a complete stop. It's a pretty freaky feeling if you don't expect it.
Told the guy at the Jeep rental company but they just shrugged their shoulders and sad "yea, ok".
