Default 2014 jku rubicon+mopar 2" lift= right pull

I am working on a 2014 Rubicon Unlimited with a Mopar 2" lift and 285/70 17 Toyo open country m/t. Only has 2800 miles on it and the lift was put on before delivery. Pulls to the right. Tried taking caster out of the left to help, and it did a little. Swapped the stock front track bar in, helped a little. More of a pull/drift now. Any ideas?

I'm curious how the caster was adjusted on one side since it's a solid axle and caster can't be changed side to side without offset ball joints. Swap front tires side to side and check air pressure in them if the TPMS was bypassed with the new wheels.

Swapping tires side to side did not change it.

Caster is adjustable by taking the knockouts out of the lower control arm bracket on the axle and using a cam bolt. It does not provide much adjustment, but I did get about .5* difference. It has the stock rims/tpm, with a bigger tire. Tires are set to the factory spec of 37 psi.

I'm well aware of the knock outs. I've cut out many. Was a caliper hose twisted doing the lift and pinching it on the pass side holding the brakes on that side dragging the caliper?

I will check this again today. Looked for this before and it was fine. The parking brakes are releasing fully.

Okay, so I spent a little time on this today. The tires are 295/70-17. Set to 37 psi. Tried 32 with no change. Took off the steering damper with no change. Put a set of new stock rims and tires on from a Sahara and all is good. Put the 295s on and put the spare on in place of the left rear. The pull returned. Rotated the spare around to all four places and still had the pull. Put the stockers back on just to make sure I wasn't crazy and the pull is gone.

Out of curiosity, have you checked the wheelbase side to side?

Might be non noticeable with small tires, but large tires might make it noticeable.

Have you thrown it on an alignment machine? That all check out with the big tires?

It has been aligned several times. On two racks. It has always been in spec.
Track is good. The front axle was shifted right, but is equal with the stock bar on.
Ride height is equal side to side as well.

Obviously it is the tires and wheel combo somehow. Balance them and check for wheel run out. I have had tires do this. My old MTRs did this and when I changed brands it went away.

I put some 255/80-17 BFG KM2s on it today and the pull is gone. Its not as wide and fits the rim much better.

I would be surprised if it was tires causing the pull, if it consistently pulled right even after you rotated them. My guess would be an underlying alignment issue that reveals itself with the wider wheelbase or overall tire contact patch. When I align lifted or lowered vehicles I like to use a temp gun to see which area of the tire is scrubbing the hardest. As soon as you lift and add wider rims and tires to a vehicle the alignment specs technically fly out the window.

I guess time will tell. I did swap another set of tires,35x12.50x18 on and it was fine. Put the Toyo combo on the jeep the 35s came from and it pulled.

No adjustable track bar for the front? 2" aint much, but might have been enough to make an adjustable track bar needed.

Did you measure the wheelbase and compare it side to side?

The track bar that came with the kit was adjustable. I had it as short as it would go and the axle was shifted right about 1/2". Put the stock one on and it was within a 1/16".

The wheel base was shorter on left after changing the caster. Rear axle measures square to the frame.
