Out of the 7 machines I have owned, all but one was out of alignment. I just found some points on the frame as "square" and used a plumb bob to make markings on my shop floor to measure from.
The Rmax was 3/4" toe in on the right side only. The driver side was 1/16 toe in. Steering wheel was also setting at 1 o'clock while driving straight with no hands. I adjusted the toe to be 3/16 in combined. Guess what the steering wheel is still at 1 o'clock. Going to find a puller to reclock it today.
Why wouldn't you adjust the tie rods so the toe in is the same on each side WITH THE WHEEL STRAIGHT. Then it will drive straight and wheel will be straight.
Used to do a lot of mechanic work often on front suspension and easy to get the wheel off slightly when doing tie rods.
You NEVER pulled the wheel to fix it. You merrily shifted the tie rods to straighten the wheel and it is the same thing here.
If wheel is off to the right when going straight you simply adjust them both to the right by the same amount and in one or two tries you will have it driving straight with the wheel dead straight too. So simple can't imagine why you would even consider pulling the wheel to fix it. Chances of you getting it straight by moving a spline are slim and you will still have to adjust the tie rods to get it right. Not only that but you are messing up the wheel being centered on the rack so it will turn more one way then the other which you do not want it to do.
Simple to fix it with the tie rods and it be done right. Just mark them and do the opposite to the other by same amount. Open up one side a turn and close the other by a turn and you will shift the wheel considerably with only a single turn on each side.
You must first adjust the tie rods anyhow to correct the toe in then you can work on straightening the wheel.
If when setting the toe-in you can move the one that is off in the direction that also favor fixing the wheel straightness then you are going to be close already just setting the correct toe-in. If not once the correct toe-in has been set you can move each the same amount and easily zero in on a perfectly straight steering wheel.
If people would just adjust the tie rods to straighten the wheel you would see how simple it is to get it exactly right. Chances of it being dead nut moving a spline makes no sense when you still have to do what you should have done in the first place.
Always use a good low pressure tire gauge and set all four tires to exactly the same before you start the procedure.
