Model A Wheel Alignment
Hey Everyone
I know people use different methods to adjust the toe on the Model A. Looking for people to share what procedure they use. I adjusted the draglink / tie rod inserts so I think it's best I do an alignment before taking her out. Thanks Ron |

Paul Shinn has a video on YouTube that's pretty good. https://youtu.be/LdNb-NU9vf0

Re: Model A Wheel Alignment
At what position on the front and back of the tires do you measure for toe? would it be 9 in the front of the tire and 3 in the back? I think the toe is 1/16 to 3/32.

Re: Model A Wheel Alignment
One should measure at the same height, front and back. I usually try and get 1/2 way up the wheel.

I know a little play in the wheel is normal but if the tow is off can that cause the car to drift? I have been working on my steering wheel play and I got more than half of it out but I still have a few inches. Hope the alignment helps her track straight down the road.

Re: Model A Wheel Alignment
FordWanted 6 inches up. If you measure higher than that changes the amount of toe in because of the wheels canted out words at the top. I think the later V-8’s had it done in a different spot and it was a different toe in. That V8 part is off the top my head.

Re: Model A Wheel Alignment
Ron, keep working on your play in the steering wheel. You should strive to have about 1/4 inch play in the wheel.
Check the caster as than can cause the car to drift. If it is off, check the ball and sockets at the end of the front wishbone.

Re: Model A Wheel Alignment
I did a quick check with a tape measure and I have .25'' tow out. I think this may be why my car wants to go left and right anytime I get over 30mph. Has anyone run into a tow out condition like this and how was your car responding on the road? I need to get a better measurement and get it to 1/16 to 3/32 tow in.

The fronts of the wheels tend to push apart when the car is moving forward, therefore any time the toe-in (or out) is measured or adjusted one should push the fronts of the wheels apart so as to remove any possible slack.

Using a toe gauge..... 1/16 toe in +- 1/32.... So 1/32 to 3/32, 6 inches above the ground on the inside of the tires

Re: Model A Wheel Alignment
I went up 6'' with an adjustable rod. Set the rod to just slip by the the raised rubber ring on the inside of the tire and then adjusted the back. When I started I had more than 1/2'' of negative toe and now I have 3/32 positive toe. I tightened everything up but did not put the pins back in as I want to take a test drive first when the rain stops.
Is it better to be on the high side at 3/32 or should I go and set it to 1/16? My car was all over the road once I hit 30 and it was a constant left right as I hit the grooves in the road but that was with a negative 1/2''. Sure hope she can go straight now lol Thanks Ron |

Ron, the simple answer to your question is Yes. As for "less than 500 miles", based on your toe-in findings alone, I would take nothing for granted on the condition of all the steering components. In this day & time, I am telling everyone that for other motorist's safety reason alone, if someone is unfamiliar (-doesn't have actual Model-A experience) with Brakes and Steering, it would be most prudent to find a mentor who has experience that can help you. |

Model A's are new to me but I have been working on classic cars for over 30 years. My car was a 10 year old body off restoration or at least that what I was told by the seller however the PO could no longer drive for the past 7 years. I noticed the car would drift left and right when going over 30 mpg so I started with looking and adjusting all front end inserts. They were a bit loose but the inserts and balls looked new. I then looked at the 7 tooth and adjusted the up down play by removing several shims and the side to side play with the screw and jam nut on the side cover. When I had the cover off the only play I could see was a bit between the worm gear and stator but it was not much. Then I looked at the alignment and found what I thing was the biggest issue with over 1/2" negative tow. I had a fellow club member help me with a brake adjustment and the car stopes very well and the brakes and cast iron drums look new as well. All fluids have been changed so I think I am good to go. Did I missing anything? Thanks Ron Last edited by Model A Ron; 04-22-2021 at 07:14 PM. |

This is all part of a long-running theme on this board that many "restorations" neglect the mechanical elements, resulting in a car that looks fantastic and drives like a drunk cow. |

Re: Model A Wheel Alignment
I understand as my car drove like a drunk cow and after seeing all the new parts it's fair to say it was off since mile 0.00.
Even my wheel bearings were a bit loose. I took them out and they looked new so I repacked them and installed them properly. I have a feeling I will be sorting things out for a bit. Ron |

I did have over 1/2'' negative tow and this is what was causing my left right shift when driving. I adjusted the tow to 1/16 positive tow at 6' up and the car drives just fine. I still feel my 2'' of play in the wheel from the 7 tooth but I can deal with that as the car is not trying to steer it's self. Thanks for the video and I think you did a good job with your box Ron |
