There is really no such thing as "bump steer" in a solid axle vehicle. Bump steer is a condition in which the toe measurement changes as the suspension cycles through it's travel. As the toe changes the vehicle's direction changes with the dominant tire. It can be quite unnerving.
With a straight axle vehicle, a solid straight tie-rod connects the wheels to the point that they cannot "steer" independently from each other.

There is an exception to this, but it only applies to early to mid 70s Ford trucks and some late model Dodges. They had a crazy version of cross-over steering called "inverted y". The main tie-rod went directly from the steering box to the right side wheel, with a secondary (short) rod that connects the left wheel from the middle of the main rod. As the suspension travels the toe changes quite a bit.
Converting away from this is as popular with the Ford guys as the part-time conversion is with the Chevy guys, because it could be done with stock parts from '78-'79 model trucks. This was all before the abomination that came along in '80. The 4 wheel drive version of the twin I-beam, called twin traction beam....true POS.
