Power steering adjustment???

Well I read my service manual this weekend about the steering coupler and it does not refer to any way to rebuild it. I read all the section on the box, pump, and steering column and the coupler shows in the diagram but no referral to coupler repair. If I am understanding you correctly, I unbolt the column and drive the roll pin out of the box side of the coupler and lift the column, sliding the coupler loose from the box. Then remove the coupler from the column and rebuild it on the bench using stock parts from any dodge/plymouth dealer. Do I have the general Idea?
TIA, Rat
