Front end shimmy

[Guest Sajac007]

I have a 47 plymouth that I drive 20 miles per day to work--always the same speed and on a smooth black top highway. The mystery is why it will shimmy one day and not the next??? The king pins and bushings are new, fairly new Corker tires, the tie rods are straight, and the wheels are not bent--help!

Yea mine does that too and i am about the same way far as new stuff. Mine is probably the bias tires
