So when I drive my jeep, it'll pull to the left or right all of a sudden, and the steering also seems very loose. Does anyone have any suggestions to fix this? It's starting to really get under my skin. I look like a drunk driver on the road. I have a 2012 jk sport with 33x12.5x17.

 

Stock or lifted? Please tell us more about your Jeep. To be honest, looking at your avatar image, it looks like you've got a pretty tall lift. If that's the case, please add in what you've done to correct castor and bump steer.

 

It has a 4" Rancho lift. I really don't know what else has been done to the suspension. I bought it new out of the show room from the dealer with the lift, wheels and tires already on it.

 

Suspension adjustments to fix caster will be a compromise between caster and pinion/drive shaft angle, probably ending with too little caster.

I would get an alignment check to see what you have for all the readings.

 

This could be the source of your handling issues.

I recently bought a 12 Rubi with a 3.5" Rough Country lift and 1/2" spring spacers stuffed on top.
Handled like crap. All over the road, couldnt track straight at all. Made people car sick, even my poor dog puked and she loves wheeling. Highway speeds were simply not safe.

Ripped all the RC suspension out after about two weeks of hating my new Jeep.
Replaced it with a simple 2.5" OME springs and shock combination. Feels like a new car now. Confident and stable at any speed.
All the wandering, swaying, bobbing, weaving, swerving, diving, dipping and general top-heavy canoe like handling is gone.

 

Thanks guys! Maybe I'll try that route if they can't fix It under warranty at the dealer Wednesday

 

How much air pressure are you running in the tires?

 

35 psi, I don't off road ever, just highway and gravel roads. Not sure if that matters..

 

Did it come with adjustable lower control arms or lower control arm bracket to adjust your front axle castor? I started with a 3" rancho lift and had the same issues you had. I fixed mine with lower control arm bracket to adjust castor and an EVO drag link flip kit to fix the steering. After those two upgraded it handles great.

I'm also running my tire pressure lower anywhere from 28 - 30 psi.

Hope you get it figured out.

 

I really don't know what my kit came with, I'll have to find out which kit was installed on my jeep. It was on it when I bought it. I really do appreciate all the input guys!
