Is Steering coupler supposed to have bearing race inside?

Post by jcannon44 »

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!

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.

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.
