C2 Steering Stabilizer (shock) Question

Re: C2 Steering Stabilizer (shock) Question

I have a 68 SB convertible with almost 97,000 original mileage. When it is driven, about 55-60 it shimmys and it does have the original damper in the steering linkage. I have entertained the idea of putting the tires from my 70 that have no rolling problems on the front of my 68 to see what would occur. Driving the 68 at 50 mph and below, have no problems and no shimmy at 70 and above.
Years ago I changed the tire rod ends to the front holes like power steering Corvettes and quicker steering movement.
When getting on the interstate I quickly accelerate above 60 when I can to bypass the shimmy speed.

It could be wheel or tire lateral runout or dynamic unbalance. Swapping the tires as you suggested should tell you whether it is a wheel and/or tire issue. If this proves to be the case, have the wheels/tires evaluated on a Hunter 9700 machine.

You should also disconnect one end of the damper and see if it offers any resistance. If not, replace it.
