At the casting bench in the sky. RIP Bret.
Any straight-axle, 4x4 vehicle with shackles ahead of the front axle, high-arched lift springs, and positive caster is going to take highway bumps hard, just the nature of the beast. Best thing I ever did to a CJ other than replace the frame with a fabbed, hydroformed frame was to put the shackles on the trailing side of the front axle. DOM tubing with accurate, fractional ID is perfect for all the mid-'70s Chevy polyurethane spring and shackle bushings, making it super-easy to fab bracketry for such a swap.
2 1950's CJ 5's and an 83 CJ8 (from Alaska, no rust!) here, plus SWMBO just got our 3rd Wrangler. It's a Jeep thing...
