My 83 240 D and 85 300D went into the shop for alignment after I replaced the Bearings--(Hint: to bang out the races without a special tool get some big Flat Washers from Sears--one size fit the race perfectly and I got it out after two whacks).

The Alignment Technician (HANSENS BEAR SAFETY SERVICE, 302 798 6741) told me front Gearboxes are worn badly and will need replacement soon. he said there is a Dead Spot at the center of BOTH.

Can the Steering Gearboxes be replaced by an amateur who gets lucky? Any hints, clues, ideas
