Reply To: front axle shock and shimmy deterrent

I ran into this when I tried to change the caster angle to make the car easier to steer. It seemed that any change to the positive made the car very shimmy prone. I tried changing the toe in but it didn’t seem to change much. I was running 45lbs in the tires. Ended up I had to take all the wedges out and run neutral caster to get it to work right.

The car has pretty heavy steering and I really wanted to get it lighter so Dot could drive it.

I think I may try changing the castor again and installing a damper to quiet the steering down. It seems pretty straight forward to clamp off between the axle and tie rod.
