Tire discounters can’t align my Dart.

I did my own alignment 2 or 3 years ago. Turned the rear UCA eccentric all the way in and the front one all the way out. Then I adjusted the front one to get about 1/2 a degree of chamber using a straight 2x4 and an angle finder. Then I set up 2x4's with the long side up in front and back of both tires (keeps the tape at the same height) and used those to measure toe.

How much caster did I get? No idea, but it's as much as I could. I'm running stock UCA's and offset bushings so more than it could be but still not as much as aftermarket UCA's.

Admittedly, toe has been an issue. Probably because I'm using the tread to measure toe rather an boards or plates on the outside of the tire. I should probably rethink how I am doing that.

Really didn't take me all that long. To the OP, I would carve out an hour and give it a shot. Then you could at least drive your car now while you wait for the appointment with the alignment shop.
