This was a common feature of straight axle cars, especially late1920s when wheels, tyres and front brakes became very heavy. It was largely to avoid it that GM pursued i.f.s in the early 30s. I do no know how it is avoided in large trucks. Modern loaded nylon steering joints impose constant friction which dampens it out Bradfords are very prone and the only sure cure is a hydarulic damper as per early VW etc. Castor has an influence. Any slackness in any joints promotes.I used to encounter in employer Land Rover. Fortunately only at low speed. Terrifying for those who have never heard of. Cannot restrain the steering wheel which flicks violently left and right. triggered by some major bump. The loads on steering arms must be very great. Slowing down resets. I have never heard of or encountered with the Seven where component sare light.
