Is Steering coupler supposed to have bearing race inside?
Is Steering coupler supposed to have bearing race inside?
I just pulled my steering box and steering shaft on my 66 Monza convertible. Unfortunately the rubber boot on the coupler was torn and needs to be replaced, my question is: should there be bearings in there? Or should I just replace the grease in there and not worry about it? Thank you for any help!

Re: Is Steering coupler supposed to have bearing race inside?
The 66 shop manual supplement has a view of the parts. No real bearing, but a pin in the shaft with a block on each side on the pin that fits into the coupler housing. This allows a little movement. There is a heavy gauge bracket on the bulkhead the coupler hits during a crash that pushes the steering box back. A type of safety device, but not good enough for the Federal regulations for the 67 models, which got the collapsible steering shaft.
You will find a ball bearing in the bottom of the upper steering shaft mast (outside tube). This bearing had a felt seal is is usually full of dirt and dried out grease. I'm always surprised how much easier the steering wheel turns when I clean and grease this bearing. It comes apart in the mast so you don't have to drive it out and replace it, BUT don't lose the little ball bearings!!! If it's badly rusted, then replace it.
By now you've probably figured out that after all these decades it's best to pull out the steering box with shaft, coupler, and upper shaft intact and rebuild it. DON'T cut a hole in the inner fender per the shop manual to unbolt the coupler, that was a cheapy way for the dealers to replace a bad steering box when parts were still new and you could unbolt the coupler. Now it's easier to just pull out the whole unit AFTER you pull the steering wheel, turn signal mechanism, and the inside mast.
I recall Clark's has a repoduction rubber coupler boot.

Re: Is Steering coupler supposed to have bearing race inside?
I don't know if the attached 1965 Corvair Assembly Manual - STEERING accurately depicts the 1966 Corvair's steering configuration, but I think they were the same, and then changed in later years to incorporate a collapsible safety design. I hope this is helpful. If you find the detailed drawings useful, you can download the entire 1965 Assembly Manual for free, or purchase the 1966 version in hard copy from Clark's Corvair Parts.

Here's a borrowed image (ignore the extra notations) showing the sliding square bearing blocks that were common in many steering coupler joints of that era. These came into use in late production 65 Corvairs.

Re: Is Steering coupler supposed to have bearing rac. Doess the pin slide out or is it pressed in so l can replace ins
I just had to replace that pin on a steering column I bought because someone tried to "hammer" it out and mushroomed the pin end so the pivot block would NOT fit on it. A press is best, but you can use a BIG brass hammer, or a brass drift, if you set the shaft on a hard wood block with a hole in it for the pin to move into. Once the pin is flush in the shaft a brass drift is best, but since the pin is inside the shaft hole you can CAREFULLY use a steel drift to push it through. Basically -- if you hammer on steel with steel somethings is going to give and it's usually the end of the pin! Brass or bronze "gives" vs. steel.
A press, if set up correctly, applies even constant pressure to move the pin without distorting it.
BTW --- This coupler system was first introduced during the middle of the 1965 model year production, so about half the 65 cars also use it. It was designed to minimize steering wheel intrusion into the "driver" during a severe front end accident. While an improvement, it did not meet the Fedreral crash standards and the Corvair got the GM "collapsible" steering column design for the 1967 model year.
