In the auto handling circles, a side motion
control link is called a panhard bar, now I
don't know if that term changes when it's
a 4x4, but the result should be about the
same, however, a car sits much lower, so
a bar between the axle and frame has a
direct attachment, witht he lift of a 4x4 I
think you would need some other mount
point on the axle to prevent a swing arm
affect (sideways) and bump steer nastyness
