Hello fellas. Couple of questions here, but first a quick run down of what I've got. I bought my newest JKU in 2018. I had a local shop weld on the EVO long arm kit (with high clearance brackets in the rear). I swapped my Dana UD60s, shocks, steering setup (Currie links and WTO hydro assist), tracbar, bump stops, etc over from my prior Jeep (an 07 JKU). Ever since the day we finished it up it has pulled to the right. I've had it at two different alignment shops and I've messed with it a ton (plumb bobs, tape measures, angle finders, rotating tires etc). I cannot get it to drive without the pull. My last Jeep with all of the same parts (actually had the same EVO arm kit welded on as well) drove perfectly straight. Sorry, I don't have alignment spec sheets to show. I've been around alignment shops for many years and know how to read the sheets, and from what I saw it was perfect after we aligned it. One of the shops is specifically an alignment shop (Alignment Specialties) here in St Louis. The dude knows his stuff and he is stumped as well. From the readouts it should drive straight.
On to the questions:
1) Has anyone had a pull or push from a hydro assist? I've had mine on stands and checked it while idling and revving it up. The front tires didn't move. Alignment Specialties said to check this.
2) My TB and draglink are real close to being parallel but are off just a bit. With an angle finder they differ about 1 degree. The TB read 7 degrees and the draglink read 6, so a degree off. Would this make it pull. I've read many times this can cause bump steer. I wouldn't say I have a lot of bump steer.
3) I just noticed tonight, right before I sat down to write this, that the two end joints on the draglink are not in alignment. The end at the pitman arm sits fairly straight, or level, and the end at the knuckle is turned slightly. Maybe it's putting a force on the knuckle making it want to turn out a bit but I couldn't imagine so. The steering wheel is straight. Thoughts? I'll check this tonight or later this week.
4) When I took it into get my first alignment the shop adjusted the thrust angle from where I set it originally (when we set the rear arms up we made them the same length for driver and pass sides. After that alignment, and it was still pulling to the right, I put it back to where I thought it was straight (using the plumb bobs and tape measure method). It still pulled. After getting tired of it again I took it to the specialty shop. He moved the axle also making the thrust angle come back into spec and it matched the first shops setup. I believe I know the answer here, but what if I added some thrust angle to help it pull left. I don't want a vehicle that doglegs down the street though lol. Thoughts?
I'm lost and after dealing with two shops it's getting very old. I've looked at everything from ball joints to warn tires, tire pressure, loose end joints on the links. Everything is tight. Help please!!
