Describe the steering feel. Which specific components were installed? Post the alignment specs. What psi are you running in the tires?

rubicon express 4 link long arm 5.5"
fox 2.0 remote res shocks
fox steering damper
30 psi
4.4 degrees positive caster
almost feels like a lot of bump steer
just a lot of feed back in the steering

Reduce your tire pressure to 25 ish. Make sure your steering stabilizer doesn't have any dead spots. Check your ball joints. I ended up replacing mine all the bump steer problems are gone.

Is your drag link flipped? With that much lift, you will have a ton of bump steer given the angle on the drag link and track bar. Really, anything over 3.5" requires a drag link flip and track bar relocation.

Definitely drop the psi, as already mentioned. I noticed a huge difference just dropping the 3-4 pounds.

My jeep only has 3k miles on it, I don't think the ball joints are bad
I'll try the tire psi and see how that works
thank you

Can you post a pick of your front end set up? I have seen some set up weirdly.

Chalk test it, don't just wing psi based off what you read...hate to see you eat tires up.
