Is it necessary to remove the hydraulic lift cover on top of the axle housing in order to remove the gear type hydraulic pump? Any tips or tricks for removing and replacing the gear type pump on the 4000?

No need to remove the lift cover. Remove the snap ring from the jumper tube connecting the pump cover to the flow control. Push the tube up into the flow control till the tube clears the pump cover. Remove the pump from the rear axle center section.
replace both jumper tube o-rings, clean the jumper tube and replace the pump cover gasket and suction tube o-ring when you reassemble.
