Thanks for that advice. When I rebuilt the front suspension, I determined that no springs were broken, so that's not it. I use a hydraulic damper to prevent shimmy, but not a panhard bar to locate the axle.

Since the axle is located by the center stud of the spring pack, which in my case is dead center, which in turn locates the axle via the shackles, and also the parallel links offer some minor trianbulation, I didn't think that a panhard bar would be required with my setup, but I can certainly see how that would solve the problem.

Since I have to rebuild the front suspension once again anyway, I was thinking that this might be a good opportunity to use that advertised kit to split the solid axle into a "poor man's" IFS. Any experience with that?
