Steering Gearbox Removal

Hi Guys,

I'm beginning the restoration of a 1971 IIa and doing it by media blasting the frame to remove old undercoating, original paint and very light surface rust. This truck has 35k miles on it and has spent its life in Colorado Springs so it's nearly rust and corrosion free. Very little has ever been removed or altered. I was able to disassemble the entire truck except for the steering gearbox (relay unit) without a single drop of LiquidWrench or cutting a single bolt or screw! It has been amazingly easy. However, I'm running into a problem getting the steering gearbox out of the frame. I removed the two retainer bolts on top, and the four bolts holding the plate in on the bottom. Soaked it in Liquidwrench and banged on the drop arm rod with no movement of the box. I even tried prying gently from the top. Am I missing something?

I was hoping to get it to the media blaster today!

Thanks,

Andy

those are / can be a bear to remove rust and grime seizes them in the mounting hole, last one I replaced, I looped a chain around chassis leaving enough droop to fit a 10 ton jack.
placed jack on loop and used it as a reverse hydraulic press, if the cylinder falls away you can get a piece of exhaust tube as a replacement and weld it in. rovers north offers that in frame cylinder.

Based on my recent experience you need to just keep repeating that process. If you removed the bolts then it is free.The steering box just corrodes to the opening in the chassis. Maybe try an equal mixture of ATF and mineral spirits and squirt it around the perimeter of the steering box. Let sit overnight and the try hammering out again. If the engine is still in, I have also read that putting a floor jack under the steering box can free it with the opposing weight of the truck.

Thanks guys! It wouldn't go with the bottle jack, so I flipped the frame over, removed the guts and hit it multiple times with a 8lb sledge back 'n forth a bit and it finally just dropped out. I have since had the frame media blasted and looking forward to fresh paint! I appreciate the suggestions!
