I wouldn't call it a cover, to me it would be end plate. Guess I need to check the parts manuel to see what the proper name is!

Ok, Tube and Plate assy (steering gear oil retainer). This is assuming you are referring to the adjustment shims on the worm gear bearings.

Should only have to remover the light control switch.

UPDATE: This is referring to the later steering boxes!!!! The early boxes have the shims on the upper bearing race (as pointed out by cas3 in post #46 below) and does require the removal of the box/column.
