Steering Rack Replacement with Steering Wheel Off
#16
Rennlist Member
I managed to fix the issue in the interim, I put the nut on the steering shaft and used vice grips to pull it back in a bit. Had my wife sit in the driver seat and fit the steering wheel whilst I pushed the steering shaft back up from below, she was able to then thread the nut into place. That spring is bloody strong... I'll be replacing the bearing shortly but this allows me to fit the rack back on.

UMM I would fix the steering column first,
as the steering wheel will be smashing the turn signal switch,
this will shear off the brass finger if you turn the wheel.
The steering wheel is not holding the shaft in the correct position,
thus the universal joint will not be properly set,
and will prevent you from pulling the shaft up further

It also appears as though the shaft housing has a notch with a corresponding cutout on the bearing, is this for the bearing to slide past?
Am I better off removing the entire shaft housing to get this out or is it easier than that?
Here are some hopefully better photos
Bush and partial bearing

I think you missed the part about chipping out the outer race ,
NOTE the outer race has fractured and let the ball bearings and the inner race fall down the shaft.
The outer race must be removed then the new outer race driven in,
pay attention to the flat edge location of the original it faces up to clear the horn tab.
NOTE sand down the mating surface of the column so its devoid of any burrs ,
this can fracture the new bearing outer race.
NOTE this whole procedure will be easier if you first remove the turn signals switch assembly,
NOTE your gonna need to have that removed to replace the broken horn contact.
Roger has new horn contact fingers.
NOTE from your picture the outer race was not supplied with your new bearing.

I'll do exactly as you, also my new bearing did come with the outer race, what was pictured previously was the old fractured inner bearing.
Appreciate your guidance!

OK now I see your new bearing ,
it appears to include the outer race.
take your time stuff a rag down the tube,
so the pieces dont fall down.

Got it all done, tapping out what was left of the bearing was a pain but went quickly once I managed to get it to bend inwards. I cleaned up any potential burrs on the inside, used a 27mm deep socket to tap the new bearing in (same as is used to remove the steering wheel, conveniently). Then I managed to pull the shaft back with vise grips, slip the bush on, and fit the c-clip after a couple of tries. All in all not that bad of a job and unbelievably worth it with how the steering now feels.
Bearing in place on spline
27mm deep socket
All back in place with new horn contact
