It's very possible that the cold weather is causing a drop in the pressure in your tires. My truck gets death wobble at lower tire pressures (below 40psi) but never gets it otherwise. Maybe try taking a pressure reading and then try increasing it over 40 and see if that makes it go away.
^this. Whether temperature is the differentiator or not, it comes down the the parts, and they’re just not solid enough. You wouldn’t believe how lightweight the stock front suspension linkage is compared to aftermarket. Jeep can replace your track bar 100 times, but they’re putting back in that same underperforming part that will fail.
I bought my first Jeep - a 1978 CJ7 (three speed manual) - in 1986 for $2,500. When it rained, water came through the dash and dripped on my feet. I was always working on the carburetor, and the rag-top roof used to sag low when heavy with snow. All that was fine - “it’s a Jeep thing” covered it, because I only spent $2,500. That Jeep was tough and went about anywhere. I tipped it on its side once wheeling in a foot of fresh snow in the middle of the night (don’t ask). Winched it out the next morning and she fired right up.
In order Ck Tire balance, Ck front End components, Ck alignment Caster for sure. I have had only 1 Vehicle at my shop I did not fix the death Wobble Dodge Ram owner didnt want to shell out the money for a frame brace kit. That being said Unless something is loose in the front end its out consider its a new truck most likely not a track bar either. Curious if the aluminum gear box could be a problem. Get a good stabilizer adjustable pressure Rubicon Express or Fox.
What you describe in your Jeep is not death wobble. DW is a violent shaking that can only be resolved by bringing the vehicle to a stop. DW will scare the crap out of you, and you will think you’ve blown a tire or something worse. I don’t know what you are describing, but it is not DW. There are a lot of great resources online if you want to research DW, what causes it, and how to resolve it. This is a good start:
Thanks, I watched that video. I haven’t experienced that Death Wobble in any 4 wheel vehicle I guess. Hopefully never will.
Death wobble for me today. 2020 Sport S , all stock 6000 miles on it.
70+mph on the interstate today, small bump and 3 to 4 seconds of violent steering wheel shake. Scared the crap out of me. I slowed down and it went away. Few miles later same thing. Small bump, violent shake, scared, and crap. Off the highway and back roads home with no issue. This is my first Jeep and I love it but the issues are getting a little crazy. Steering parts have been on order for more than a month for my other steering issue, steering wander, and I just noticed the other day that my back window is leaking. My wife drives the Gladiator most of the time and now I'm not real comfortable putting her behind the wheel. I've seen all the fixes on this thread and online, but this is all on the dealer, I paid way too much to be fixing these problems, and it sucks taking time out of my schedule to fix a new truck. Looks like the dealer gets a call tomorrow. @JeepCares I could use a little help here. Happy Thanksging
For one what you got going on is definitely not death wobble, that's a tire out of balance or bent wheel or something of that nature. Could possible be a loose track bar or drag link, bad ball joints but I'm leaning more to a wheel or tire issue. If it was real death wobble you wouldn't be going 70mph, and the the steering would be violently shaking side to side not as yours is doing. I'd have my tires and wheels checked for balance issues. Colder temps can make out of balance tires feel worse because of the fluctuations in the tire pressure from hot to cold.
If everything is tight, and tires are balanced, then, death wobble can also be caused by too much toe in. I would take a paint pen and mark the current location on the tie bar to mark the stock setting, then, I would reduce the toe in by about 1/4th of a turn and drive it. If it helps, I might go another 1/8 turn. Just a small turn, really changes it. Toe in can be anything from zero to 1/8" or more, so that variability, can push you into possible vibration issues.
Tires are stiffer. Bushings are stiffer. Shock are stiffer.
A wheel or tire issue gets progressively worse as speed increases and is 100% consistent. Slow to X speed and its not noticeable. Speed up to Y speed and it is the same intensity every time.
