Searched the site for a detailed disassembly procedure for my truck's steering gearbox. The gearbox has been removed from the truck and disassembled down to the input shaft/piston being removed...even dropped the ball bearings out of it. Need to replace the input shaft seal but question how to disassemble the input shaft/piston assembly. I am new to the site and may have missed this thread if previously posted. Thanks for your help!
