Need Help after removing 35s. " Shimmy " issue

[Mezak]

I currently have a 2020 Gladiator Sport Max Tow with Factory Rubicon front shocks/springs takeoffs and a new Fox 2.0 steering stabilizer with only 35k miles on my truck. I just sold my 35s Toyo Open Country 35x11.5x17 for the time being and put back on my factory dueler/steely wheels+Tires. I keep having that " Shimmy " issue now when I hit a crazy bump on the highway doing 60+ it starts shaking uncontrobbly until I slow down. I double checked the torque specs on everything and they are correct and also just had my old wheels checked to make sure they are balanaced. Do you think the smaller tires are causing this or do you think the basically 1 year old steering stabalizer failed already?

Stabilizers only mitigate and mask DW. They're not a cure. A properly setup rig will run fine and not wobble with no stabilizer on it.

Maybe Jeep doesn't care will chime in, lol.

I would:
Double check your “toe” alignment
Play around with tire psi
Rebalance tires
Make sure all your draglink, tie rod, ball joints and trac bar joints are tight and to spec.

Thanks thanks, I saw that bulletin Jeep put out and saw how many people just changed there stabilizer bar and resolved the issues def just a shimmy not a death wobble

So which one is it? The way you describe it, if it doesn’t stop until you slow down, that’s death wobble. I’m gonna go out on a limb and say tire pressures may be too high to start.

Same theory. A steering stabilizer is a like a shock absorber on the steering linkage. It helps to mitigate road forces and lessen the chances of bump steer on solid axles.
The core issue will wear out a new one over time, the same way it did the factory one.
Jeep loves to toss them on when an owner complains about shimmy because it's cheap and easy, and the problem will appear to go away for a while.

.. First thing I checked and they were only at 32lbs

Def shimmy..I am just completely lost because the day prior 0 issues with my 35s same highway same bump

The only way to fix death wobble and every other problem Jeep has is by getting an office building full of PR people whose only skill is to tell people what they want to hear and be polite. These people, should, of course, know absolutely nothing about the issues they're charged to mitigate, but will accept minimum wage, and if things get real, just ignore the customer. The objective for Jeep and Ram, is to suck slide, whenever, wherever possible. I don't know how many of you guys have been in a dealership shop since 2019, but they're full of 19 year olds and homeless people willing to work for peanuts. people who have major issues, ie valve train, paid 50-60K for a brand new, factory built truck, which will now be torn apart and reassembled by an imbecile. Every one of those trucks should be replaced with a new, factory built truck, no questions asked, and Stellantis can take the loss for their incompetence. Change my mind, Jeep cares.

ehh thats rarely the cause but can be part of it. Make sure the tires are properly balanced. And I'd take it in to have ball joints, tierods, drag link, track bar, and toe alignment checked. if everything is done right and in proper working order, you would be able to drive without a stabilizer. Honestly thats the first thing i test for. Take off the stabilizer and whip it around the block. If the vibration goes away then yea its the stabilizer. If it immediately gets worse, its something else.

It only happens when I hit a crazy bump at 60+ mph

take it off and hit a bump at 60. the steering stabilizer could be cavitating. I got a stretch of 15 mph bumps in my neighborhood. I just make sure no one is out and hit em at 45-50. If it cycles with no wobbles, i know everything is good.

 

[Reddout99]

I would suggest rebalance first.
I started to develop a "shimmy" from around 40-45mph. Had the tires road-force balanced yesterday and all is well.

Could it be the cold weather you think? The fox stabilizer is under a year old, i am debating on putting the stock back on.

cold? i wouldn't think so. Normally they go bad when they either lose fluid or get water/air in them. Thats was causes the wobble. It gets hit hard, which causes the piston to move fast enough to heat up any moisture in the fluid. this causes it to vaporize and expand rapidly forcing the piston away from compression. however vapor can be compressed so it fights itself as the vapor doesn't wanna mix with the fluid. which causes bubbles and cavitation and yada yada, the list goes on. But yeah throw the stock one on and see if the problem is still there. easiest way to tell is to eliminate what is causing the problem. Its not the first stabilizer I've seen go bad but its rarely the only bad part.
