Darting steering after lift

Installed a daystar bb lift on my '00 TJ. Kit came with a bracket for the front and rear trackbars to be relocated. Now everytime i hit a bump or turn corners the steering seems to dart. There's no wobble. Would I be better off removing the brackets and drilling a hole for the front trackbar to re-center the front axle ? BTW its a 2 1/2"bb lift with JK shocks. Just not sure what im dealing with here.

Do you have a drop pitman arm on there?

Drop pitman arm should solve this. I ran into this after lifting mine. I ended up doing Iron Rock Offroad's over the knuckle steering.

False.. Drop pitman arms cause bump steer 99% of the time. The geometry and angles of all of the steering components after the lift need to stay the same as they were before the lift. And drop pitmans arms are usually generalized for 2-4" of lift... which would not keep all the angles the same. The OP may need to add something, but it's probably not a drop pitman arm.

To the OP, take some pictures of your steering components and post them up here. Like a straight on pic of the front axle and then from a few angles like side view and underneath. That'll help us diagnose your problem.

Well looks like everything is in fairly good order. No drop pitman which is good.
Personally, I'd get an adjustable front track bar or remount it to the original stock location. But I don't think that's us your main problem. Are you still on stock CA's?

looks pretty normal... Have you been up to highway speed with this?

Looks like your steering damper is new...did you replace it trying to eliminate this problem?

As it is right now, I'd say its probably the changed caster from the lift that feels different, and you won't fix that without new CAs or different ball joints etc. The change in caster from stock to 2.5" shouldn't really make it un-drivable, so I guess you either get used to it or get adjustable CAs or balljoints to change caster.

Did you align the front end after the lift? You need to check your toe in.

Stock ca's. I've done the self alignment and im pretty close. I just wasnt sure if the bracket they provided was junk. I heard of people just drilling a new hole to the right of the old one.
It's not bad to drive. The lift might have made my bal joint wear more noticable. The SS was changed because of the larger tires and alittle of the jerky steering. Didnt help with the later

Checked that after putting the lift in. Im 1/8 inch diff. I have recently changed to a size bigger tire. Should I re check my toe?

Usually always toe'd out or low caster that causes darting
