'61 Apache - Problem with reverse

[AD8]

I just recalled... The only instances where this problem occured was when the wheel was cranked hard, at low speed, one way or the other - reverse only. Could there be some bending or flexing at these extremes that is interfering with the normal function of the linkage, as it is tied to the steering shaft?

It has been suggested that worn motor motor mounts could be the cause. Would that still apply when, at each occurance, the engine was at idle (not much torque)?

I have a friend coming by later in the week to operate behind the wheel while the invetigation continues.

Thanks,
