alignment? any specs on your jeep? stock, lifted aftermarket suspension and steering components?

 

4" lift

 

just springs? control arms? track bars? etc.

the more info we have the more accurate the answers.

sounds like caster, but could be a lot of different things

 

X2 on caster. Did you install a lift on it recently? Control Arms?

 

What changed before it started swerving? Was a dropped Pitman arm recently installed? Does the road you're on have bumps/dips on it when the swerving happens? Was a suspension lift recently installed? Was the toe-in adjusted afterward?

 

Check both of your sway bars and make sure all of your links are good.

 

I have large oversize mud tires extend about 50 percent outside the fender flair. I have had everything aligned tightened and checked, she over responds to steering inputs, at 50 to 55 mph. Tires are brand new Aluminum wheels, good balance, new air ride shocks. And she do get very touchy on the steer. I am never in a hurry especially in my TJ, take it nice and easy.

 

are you saying its a jeep thing, dont worry about it?

 

My TJ started to shake if it took it over 55. Mechanic said i need u joints, steering stabilizer so started with u joints, next we replaced the factory steering stabilizer. Now it is doing much better but I still can feel vibrations in the wheels if I go over 55.
Our next guess is the track bar.
So, long story short, you should share all that you have done to the jeep and any thing you've tried to correct the issue. Good luck and happy jeepin

 

A steering stabilizer is never the cause of shakes or vibes. It will simply mask it some until it is overpowered by the true problem. Do a dry steering test to locate loose/worn parts in your steering/suspension.

 

I noticed sway and steering sensitivity when I test drove my Wrangler around the block. I still get it on the highway at any speed. My salesman didn't know anything about it. I thought maybe it was just how all-terrain tires roll. Never had them before. The sway seems to be affected by the wind which I would expect. Mine doesn't feel like it is about to lose control. I don't feel anxious but it is annoying.

 

is it lifted? how much psi in the tires? when was it last aligned? toe in and caster numbers? a softtop in the wind does act like a sail to some extent, but a properly set up TJ should drive straight with minimal effort
