Tilt lower bearing removal - The 1947 - Present Chevrolet & GMC Truck Message Board Network

70LonghornCST · 07-18-2008, 01:32 PM

I just bought a Tilt steering column from a 1970 GM truck. I did a "search" here and found many posts on columns, but could not find one on this exact aspect: bearing removal.

When I turn the mast I can hear a grinding sound like there is dirt or metal bits in the lower bearing. I have ordered a new lower tilt bearing and plastic housing. But, how do you remove the bearing from the shaft (mast)? I know there is a metal clip and bearing retainer, but after those are removed, how does one proceed to
remove the bearing from the shaft? I just don't want to mess anything up. Please enlighten me!

Thanks!
-Richard

Hope this helps?

70LonghornCST · 07-18-2008, 04:42 PM

It does, thanks Dan!

However, how does one remove the lower bearing? Is there a special tool, or does one just wiggle, pry, and tap it off?

JimKshortstep4x4 · 07-18-2008, 09:19 PM

The bearing just slides off of the shaft but it helps to clean the shaft first with fine sand paper. Lube the shaft with a penetrant, also.

After that "wiggle, pry, and tap" it off. (I assume that you have the snap ring removed).

Just did one of these, our bearing was plenty rusty on the shaft, and the retainer was made of plastic. Soak it up with BB blaster, and wiggle, pry, tap !!!

70LonghornCST · 07-18-2008, 11:15 PM

Thanks guys! LOL!!! Yes, the snap ring is off. I'll give 'er a shot.

I'm glad someone brought up this point, because I'm planning on rebuild the tilt column this summer. Good luck Richard!

FRENCHBLUE72 · 07-19-2008, 09:42 AM

Has anyone ever done a write up on a tilt rebuild?

72BlckButy · 07-19-2008, 11:40 PM

Not from what I've found on the board, but I think that it is definitely needed.

When I start the rebuild on my column I will have to catch a picture, and if no one has started one I will try my best to create one.

70LonghornCST · 07-20-2008, 01:37 AM

Well, that did the trick. I got the lower bearing off. Thanks! I did not need to remove the upper as it was fine. Besides, I am a visual learner and getting the top part of the column apart without pictures is not something I wanted to do if I didn't need to.

The bummer news is that the column that I am rebuilding I just bought off of eBay. The seller advertised it as "off of a 1970 Chevy Truck." So, I figure that I'll just use it and colapse that shaft as I have read.

Is there a write up with pictures on colapsing the intermediate shaft at the plastic rivits? I would like to see for certain where and what I need to do the mod.

JimKshortstep4x4 · 07-20-2008, 02:56 AM

If the column you have is an original truck column, collapsing the shaft is not needed.

Jim

70LonghornCST · 07-20-2008, 03:09 AM

...oops, I meant to say that the seller advertised it as "off of a 1970 Chevy Truck." Howerver, it has the long shaft and it so it is a VAN column. Instead of dealing with sending it back and so on, I just figure that I'll just use it anyways and colapse that shaft as I have read somewhere. But pictures and a write up would definately be of help.

70GMCer · 07-20-2008, 09:23 AM

I just used a hammer with the shaft off the column & in a vise. Couple hits on the end on the shaft, & the plastic rivets give.

Do I need to cover the ends to protect them from the hammer? Or do you not have to hit it that hard?

I have a couple questions in regaurds to getting the van column to work:

1. What about the neutral safety switch? Do I need to move its location? If so, do I need to cut a similar sized slot into the column sleeve?

2. Does the slined (van) steering shaft bolt right up (fit) the intermediate shaft on a truck?

3. Once the intermediate shaft is colapsed, and you have it all bolted back together, is there play or slop in the shaft? Should I
re-drill and insert some bolts or screws where the old rivit holes were to tighten it up?
