MOPAR brethren (and sisterhood): I'm posting the following for what it's worth, in the hopes that it may help someone else. My 1974 Duster that I bought in 2019 with 238K miles had a noticeable shimmy (wobble) in the steering wheel above 55 mph. You could also feel the wobble in the car the faster you drove. I had all four wheels rebalanced, but that didn't help. The only front end components that weren't factory original were the lower ball joints. What did help was rebuilding the front...
My bothersome shimmy went away. Yay!
