[R-390] RF sub chassis slug rack problem

[Barry]

Didn't some of the slug racks have non-rolling "bearings"?  In other words,
they were there just to keep the slug rack aligned, but didn't roll.  I
think some of my Motorola racks are that way.  Perhaps your RF deck has a
renegade slug rack from another deck?
