Steering Shaft

Hey Folks,
Quick question: I'm setting up my power steering box in my 52, and I'd like to know if there is anything wrong with getting a longer DD shaft and attaching it to the steering column.
Do you guys think I'll need a heim joint to support the steering shaft at all?


Thanks a bunch!

Re: Steering Shaft

if it were me I would get a telescopic shaft so the cab can move some without affecting the steering column.
if the column has a good bearing at the bottom and good support at the firewall and above then you should be ok without a support bearing. that would also complicate the cab movement interference.

Re: Steering Shaft

Thanks dsraven!
The upper steering joint flexes (it cost something like $80?)
It's supposed to be a better solution to a rag joint, maybe that's no enough flex. We'll see.

Re: Steering Shaft

I used combo of 74 truck and astro van parts to get a slip shaft because I know how much the frame will flex off road. with only two joints you do not need any intermediate support. Both steering box and my GM column had 3/4 splines, intermediate at DD configuration pinned and spot welded. Slip has about 1.5-2" travel.

Re: Steering Shaft

how much flex is built into the cab/frame? ensure enough extension/retraction is also built into the steering shaft. set some weight (friends)n in the cab and have them bounce around a bit to see how much the cab moves in relationship to the frame, then add a bit for worst case scenario and call it done. I like Orrie's idea of using stock parts.

Re: Steering Shaft

Unless you are going four wheeling I don't think a street rig has much worries about cab and frame flex with two U joints in the mix. Remember the original box has a solid shaft and column and unless the cab mounts are shot you don't have a flex issue.

Some guys like the slip joint in the shaft to take up the impact if you do get in a wreck. Better to have it collapse than push the wheel into your face and chest.

Re: Steering Shaft

i prefer the long straight shaft over an intermediate heim joint
the straight shaft is locked in place, can't come loose even if all the set screws are removed
if you can run it straight just do it

This much, on this trip I cracked the weld at the bottom of the A pillar to cab (not in this pick). This is the reason I kept all the frame rivets and not welded. Over the years I cork screwed the frame pretty good.

Re: Steering Shaft

I've always connected the box to the column directly and never had a problem.
