I have installed an AEV DualSport SC Suspension 3.5" last week. After some test driving I found nothing wrong, the Wrangler was running perfectly straight.

I took it to Tire Barn for a wheel alignment anyway because I wanted know if I had misaligned anything imperceptible and if the caster was in the specified range.

Since the wheel alignment the Wrangler pulls to the left significantly. I have copied the results from Tire Barn below.

It looks like the toe was out of spec before. Do you think it might help to adjust the toe back to what it used to be before the alignment? The guys at Tire Barn have no idea.

 

No way. You had way too much toe in to start which prob added stability, but left like that will chew up the tires.
Caster looks perfect.

What tires do you have ? Some tires tread design will cause a slight pull.

Try disconnecting your SS. Higher charged SS's can also push the jeep left.

Camber. Something is not right there. Looks excessive. You wheel?
I'm not sure if camber will cause a problem other than tire wear.

 

The SS is an Old Man Emu which is said to be a good match for the JK. It is not a gas pressure damper so it doesn't push at all. I will keep it in mind though even if I didn't have that pull before the wheel alignment.

The actual reading of the FR camber is in deed so off that it seems like the reflector had been messed with during the alignment. At least I didn't wheel it during before and actual. ;-)

So what else could it be? They have definitely worked on the tie rod and the drag link. But what advise can I give them so that they can eliminate the pull?

I have 35" Goodyear Duratracs with about 3000 miles on them.

 

Is your air pressure the same in both front tires? Is your axle centered? Do you have C gussets? If not, it's possible you bent your Cs with the larger tires. Your toe in should be 1/16" to 1/8".

 

U need about a 4 degree split on the caster we normally do this with a adjustable upper ball joint. This will solve ur problems

 

I meant 4 point so adjust it to 4.7 on the one side

 

Swap your front tires from side to side. Does it still pull to the left? Does it pull to the right? If it pulls to the right it could be a tire problem.

 

For what it's worth, my brother and I installed an AEV 3.5 SC lift on my 2012 JKUR. It was fine afterward. We had access to deserted pavement and we gave it a thorough testing. No pulling, no issues at all, even at 95+ mph.

i then took it to a Firestone for alignment just for assurance all was well so my tires would wear evenly. I drove out of there with a pull and a broken clockspring in the steering.

I then took it to the dealership. They aligned it and even fixed the clockspring under warranty. They initially said some guys can break the clockspring installing some lifts. They were cool about it, just speaking informatively and not being defensive or demanding it was due to the lift. I showed them the lift instructions and they could see that nothing above the draglink was touched. I paid for the alignment and got compliments from the service tech regarding the handling when he gave me back my keys after his test drive.

The dealership's alignment was dead on and my jeep was back to the perfect steering I had before I paid Firestone for a headache.

Moral of the story, I probably should have just skipped the alignment, and not all alignment shops are good at their work. I doubt Firestone will ever see another dime of my money. If the other DIY remedies offered here don't fix your issue, consider another alignment shop.

good luck.

 

Caster is fine. Assuming he has drop brackets anyways. Adj ball joints fix camber.
I like the switch tire idea.
The excessive toe maybe helped ?
So adj to within specs it now pulls. Like I said, the tires would not last long toe'd in over 1/4"

Switch the tires and see if it makes a difference.

 

I should add that the alignment was done earlier this week and the pull occurred immediately after the alignment.

Looking at the FR camber and knowing that it is not adjustable, would you agree that a head must have slipped off? If so is it possible that they have misaligned the toe as a result of the slipped head? Would the toe create the pull then?
