Thank you all for your useful reply to my questions a la oiler system on front suspension.
To update you, the complete system was renewed and new kingpins and bushes, shockers installed.
To my amazement, the care still shimmy's violently side to side at about 40 mph?
I did the conversion in the hope that the shimmy problem would be cured, but alas it is still there?
The only part that was not renewed are the S/S blades and shims.
When the shimmy starts each side of the front of the car jumps up and down from side to side and I have to brake quickly and it then stops.
I am wondering if fitting a pair of brake reaction bars to the front crossheads may help in taming the wobble.
They seem to be a fitting that one uses to eliminate the effects of harsh braking, which I never do anyway. The car is a 1973 4/4 2 seater, and I would be most interested if others with the same model have experienced the same problem?
regards
Peter
