Default Untamed JK -- It doesn't want to drive straight

My toe-in is good! My steering wheel is centered!

The deal is my JK wants to steer to the right instead of stay straight. If I let go of the steering wheel, the JK veers towards the right. At times (highway speeds), I can feel the JK wanting to veer to right even as I hold the wheel so it stays straight. And, something I noticed is it takes no effort to the turn the wheel to the right, BUT, turning the steering wheel to the left feels like it takes a tad more of a jerk.

All I have done to it is a 2" BB w/new shocks. Didn't change the steering stabilizer or track bars as neither seem needed with a budget boost. I also have 33x12.50 tires and my wheel backspacing is 3.75" and I know my tires are aired properly as my sensors haven't gone off and because I've checked the air pressure.

Thanks!

09Rubicon -- Thanks for the bump, was just about to do it myself.

Can anyone kind of help solve my steering/stability problem or point me in the right direction with some suggestions?

First thing I would do is swap your tires from one side to the other. If the pull goes away or changes direction you know its in the tires. If switching tires doesnt produce any change the next step is take it to an alignment shop and get the alignment specs. Be sure you tell them what your dealing with up front. Altho in stock trim the caster isnt adjustable it is possible something has gotten bent or not welded in the proper position from the factory to cause the caster to be off enough to cause a pull. Make sure they give you a before and after print out of the specs. Just because the machine says its "in the green" doesnt mean the specs cant be skewed enough to cause a problem.

How much air do you have in your tires? I think that since you have bigger tires the PSI should be lower than stock specs, so just because your sensors aren't indicating a problem doesn't mean its at the correct pressure. For 33s usually around 30PSI is where they are supposed to be. Do the chalk test. If the tire sensors act up you can always get that fixed at the dealer getting your computer flashed.

Anyways, it does sound like you have a tire pulling you. Swap the tires around and see what happens. Also don't be surprised if both front tires are pulling you in the same direction

Summary:
1. Check tire pressure (chalk test)
2. swap front tires
3. If all else fails move your front tires to the rear or have a road force tire balance.

Good luck!

Thanks for the replies. I'll take it to an alignment specialist and at least get the specs and get everything checked. I'll check the control arms in the morning and see if they're okay before swapping tires.

Keep the replies coming, through. I love the help and possible solutions.

Quick question -- What does switching the tires around do besides distribute the amount of wear & tire?

You probably have what is called a radial tire pull. It's not uncommon. The tire has a greater resistance to rolling one direction over the other. You're wasting your money with the ailgnment shop. There's not an angle on your jeep that is adjustable from the factory that will cause a pull of any kind. It's your money, though. Go for it.

Something else you can do is get a friend to follow you. If they stay back a slight distance have them check for crabbing or anything else unusual. Crabbing is when the rear and the front are not aligned in sync and the vehicle does not go forward in a straight line. You or they will see the rear following an inch or two to one side or the other. Measuring from wheel to wheel on each side can also help determine that, but not always.

Any time there seems to be suspension issues if a vehicle is driveable it is a good idea to have someone follow you, then check one side and the other while going down the road.
