Have a close and critical look at suspension rubbers - especially on that big long metal bar what locates the front axle., swivel hub lash, condition of the bump stops.
Poly bushes are best left to Jap 4WDs, the Classic was designed for/with soft-ish, compliant RUBBER bushes, change them at your peril... - for road comfort.
Checked all wheel nuts recently?
Are the tyres much rounder at the top than the bottom ???
