Default Steering Column lower bearing

I rebuilt my T/T steering column and have it back together and everything works.

What should be the easiest part of this job has me puzzled. Per the attached document I can see no way the bearing is contained in place. It just slides off the shaft with everything assembled.

Any ideas? Did I receive the wrong replacement bearing? The other two parts match my old parts correctly. The old bearing was cut off because it was fronzen on the shaft so I have nothing to compare.

The bearing needs to be pressed into the adapter. Then the bearing and adapter assembly goes into the retainer.

I just put my column back in today and I replaced the lower bearing also. The adapter has a small cut out that the bearing is pressed into. It is only about 1/4 to 3/8 of an inch recess that the bearing sits into and on my GM bearing it also had an o-ring inside the inner part of the bearing that held the bearing tight onto the shaft.

My 71 has a slot cut into both sides of the metal column. The plastic housing for the bearing also,,has two slots. When installed there is a circlip that locks the two together.

Thanks guys. I think you are both right. My bearing "snaps" into the adapter but just falls out and slides down the shaft. Jim's papers indicate to "slide" the bearing and retainer up the shaft which implies it is a slip fit on the shaft as mine is.

I have a circlip on my '73 but it only locks the reinforcement #69 to the colar of the shaft and not the adapter (retainer) #67 or the bearing.

So, either I have to rely on rust and corrosion to hold the bearing in place (it sure had the old one held in place. I had to cut it out with a Dremel). Or, find some other way to bind the inner race to the shaft.

The retainer and the clip are what keeps the bearing from sliding down the shaft. When I put my bearing in the adapter It took some force to get it seated. No way was it going to fall out. With the bearing in the adapter, put the assembly into the retainer making sure the three recessed areas on the adapter are lined up with the three slots on the retainer. Slide the whole assembly onto the shaft until the three slots on the retainer match up to the three slots on the column housing. When you put the clip in it goes throuth the slots in the retainer and the slots in the column housing, thats what keeps the bearing assembly from sliding down the shaft. If the bottom picture in your post is the way you have it set up, the bearing is on the wrong side of the retainer. Mine was hard to do, trying to compress the spring while putting the retainer clip in.

I've tried various ways to assemble the 3 components. The only way that they go together is the way I have it and it looks like the exploded view in the service manual. The adapter and retainer (reinforcement) stay in place on the collar with the clip #70 but the bearing just slides out of the i.d. of the retainer and slides down the shaft. I have no press fit of the bearing and the i.d. of the retainer is bigger than the o.d. of the bearing so it just slides past and off.

You mentioned "sliding the whole assembly onto the shaft". Was yours a slip fit or as others have mentioned they have a press fit? My bearing just slips up the shaft.

The tilt/tele doesn't have a spring.

Anyone have a pic of the adapter, bearing and retainer unassembled but lined up in the correct orientation for assembly?

The bearing goes in first then the retainer then the clip. It's a snug fit, you may need to clean up the shaft and/or the column tube with some emery cloth to remove any rust build up.

I just looked at Jim Shea's steering papers, you are corrrect, they say the tilt/tele column doesn't have a spring. When I rebuilt my column last year (1972 tilt/tele) I replaced the lower bearing and mine had the spring in it. The kit I ordered had a spring in it so I replaced the spring. I've owned the car since 1988 so it's had the spring in it the whole time. Boy, I sure don't feel like pulling the column to take the spring out. Anyway, I just looked at my old bearing assembly and the bearing is definitely seated into the adapter. the order of the assembly on the shaft is the bearing adapter first, then the bearing which is seated into the adapter (the larger face of the bearing should be pointed outward towards the steering box) and then the retainer. Hope this helps. Yes, mine was a slip fit.

Thanks to you all for the help and comments. I'm convinced I am installing the parts correctly. I am going to buy (again) another bearing and adapter and see if they fit together with a press fit and that the bearing has a press or tight fit on the shaft. Currently the bearing is a loose slide fit on the shaft.

Unless anyone sees something backwards or in the wrong order in the pix I'm going forward. I understand how the circle clip snaps into the slots, etc. so clocking the parts not the issue.

The order in which you have the parts is correct. However, the bearing and the adapter (white plastic piece) go on as a single unit. When I put my bearing into the adapter I put a little lubricant on the part of the bearing that goes into the adapter housing and had to give it a pretty good whack with a seal installer to get it to seat.

Certainly looks right to me. Does the bearing fit into the adapter when it is not in the tube? It's been a while since I did mine, but I remember everything went together fairly easily. Try a little lube on the outside of the bearing

The bearing does fit into the adapter when it is not in the tube. It's just not a press fit nor is the bearing a press fit on the shaft so I'm reordering both.
