I meant the wheels pointing straight ahead with the steering wheel centered. I should have explained that better.bretto said:What do you mean but getting the wheels centered? In respect to the body? Trackbar does that. Or do you mean in respects to the steering wheel?
Wiley Coyote said:XJs use that wonderful inverted y steering set up. The tie rod and draglink connect to each other (instead of directly to the axle like most other vehicles). You have to adjust the tie rod and draglink simultaneously to get the wheels centered and the toe in set correctly. It’s a trial and error kind of thing; adjust the tie rod to get the toe in set right, then adjust the draglink to center the wheels, now go back and readjust the tie rod again, then check the draglink. Repete mulitple times until everything is set correctly. That’s why it’s a major pia to do it in your garage. It’s much easier to adjust everything while it’s on an alignment rack, plus the machine shows you when you are centered – much faster than using a tape measure.
On an inverted y steering set up, lifting the vehicle will change the toe in. The draglink goes from the pitman arm to the passenger side knuckle. The tie rod goes from the drivers side knuckle to the draglink (about a foot from the passenger side knuckle). As you lift the vehicle it alters the angles between the pitman arm and the draglink; the draglink and the passenger side knuckle; and also the tie rod and draglink. Trust me, the toe in will have to be reset. It took me a couple of hours on an alignment rack to get the wheels centered, steering wheel centered and the toe in set correctly. The problem is as you adjust the draglink to get the wheels and steering wheel centered it alters the toe in adjustment. You have to go back and forth a couple of times till you find the right combination of draglink and tie rod adjustment that gets everything centered. Like I said, it can be done in a garage, but it is a major pia. It is much easier to just get the toe in and wheels centered and not worry about how the steering wheel looks. It’s not correct, but a lot of people do it. Next time you see a lifted Jeep go look and see if their steering wheel is cockeyed. :laugh3:bretto said:If I think about it, lifting won't change toe though.

You don’t have to check it a million times, but you do need to adjust it more than once to get the steering wheel straight (assuming you got the toe in correct the first time and none of your adjustments altered it). If you PM me your email address I’d send you the Wheel Alignment section of a Factory Service Manual. I would post it here, but they get kind of upset about it.bj-666 said:what are you talking about. to adjust the toe you adjust the draglink so you pass side tire is straight and so is you wheel then you adjust the tie rod bringing the toe within spec no need to adjust and check a million times.
I see...yeah with lifting and with the dumb inverted-y the drag link essentially pulls the drivers tire inward as the drag link's angle changes. I had to draw a pic. That may explain my tire wear on the outside edge and the pull to the right.Wiley Coyote said:On an inverted y steering set up, lifting the vehicle will change the toe in.
