Default Front end shimmy solved

I had a pretty good (bad) shimmy in the front end of the Model A that seemed to come and go depending on travel speed. My passenger said it seemed to be coming from the right front wheel, so when I got back home I jacked up that side and placed a piece of 2x8 against the tire and spun the wheel. There was over 1/4 inch of runout (wobble) in the tire. I put a different tire and rim on the front that had much less runout and took it for a test drive. It was much better, still not perfect, but no more death wobble at certain speeds. I think I'm still going to install the steering damper from Snyders. Moral of the story, try the simple things first.

Its just an opinion, but, a steering damper is a bandaid.

A properly prepared Model A does not need a steering damper.

If it were my car, I would go over the complete front end. Once everything is right, it will last a long time.

Tires, spring, rims, shocks, steering box, front end, wishbone. After 90 years, a little wear here and there in the front end and you have a problem that will just be concealed with the damper.

If not properly fixed, your shimmy mostlikely will be back.

I work on lots of front ends and also straightened the wobble of many wheels.

1/4" wobble contributes to but is not the only cause of your bad shimmy.

I agree with those above that suggest a close inspection of the front end and repair/adjust what is needed.

I have a "Do it yourself" article on my website that explains how to remove the "wobble" from your wheels. Look for: Wheel Wobble Reduction by Spoke shrinking

Good Day!

Take off your tie rod and drag link and examine your steering balls. My guess is that they are egg/football shaped. This was the case with my death wobble
