a newbie to the side car thing-- bought a 1975 thompson cycle car from estate sale a block away very cheap.- to hook up to my old 1974 Z1 900 kaw.- replaced a spacer missing in the bearing swingarm of the sidecar(had a heck of a lot of slack) -- made brackets at the engine mountings ect. after a couple of tries and wasted iron ect. but had the wobble at 20 mph.-- so at what would be the center of the sidecar frame(so toe in can still be adjusted) I made a 5th lower mount off the center stand and the wobble seems gone. what I say is the wobble on side cars could be not having a solid connection between motorcycle and side car?
definetly poor conecction gives you a hell of the time.
But wrong alignment too.
And bad pivoting points like stearing bearings, fork, back swing, SC suspension or wheel bearings have lots of impact too.
