loose steering, traced to steering column

I have a lose steering column on my 2002 Freightliner FL112. I have narrowed the "wiggle" down to the area I highlighted on the parts diagram breakdown. I am not a mechanic so i apologize for not using proper terms. It is where the splines and bearing(?) unison. How can i rig something up to make this tighter? I have a welder and some free time. I do not want to disassemble the steering column as I am told it would be a nightmare to reassemble. I also have a cutting wheel (as that is how i exposed the part to begin with). Any advice would be really appreciated regarding what i can do next.

 

hope i am saying this properly but the slip appears to be coming from where the bearing and the shaft/u joint assembly attach. I have no information regarding how this works, or what i should cut/weld/tighten/ or unscrew.

 

Nahhh id prefer to run over all you truckers too lazy to repair your rides. NEXT

 

You have no clue the endless repairs ive done so far, im positive this is cake. didnt ask for your moronic opinion i asked for advice on how to repair but quite obviously
we are now well past that point so irritate someone else with your trollish opinions

 

Lol go to a mechanic....LOL .. the mechanic is the one who failed to diagnose this problem in the first place!! I hold a masters degree, a pilots liscense, all my cdl endorsements, own a fleet of 5 trucks, im pretty #### sure i can figure out how to make two pieces of metal tight with some simple guidance instead of your ####### opinion and judgement.

 

Never screwed with steering columns internals before, all new me. Never claimed to be a mechanic actually stated im not i have much loftier persuits. Odd even the diesel trained mechanics at the dealer have no idea how to disassemble and rebuild it...hmmmm

 

the problem looks very similar to that video.
