'67 Front Spindle Steering Arm Mount Nuts

[Leif A.]

I noticed when servicing my '67 a few weeks back that the front spindle steering arm mount nuts were loose...what a mini PITA this is going to be having to remove so much "stuff" just to get to the head of the bolt. My question is, are the nuts a "one time use only" type. I know they're self locking so I'm guessing they're one and done. Just want to have new ones on hand should I need them.
Or, does anyone have any ideas as to how to tighten the nuts without being able to get to the head of the bolt to hold it.
Thanks guys.

The nuts can be re-used. In fact, the exact same nuts were used on the rocker arms of many Chevrolet engines and those nuts are commonly re-used. However, if your nuts have loosened, that's a sign that they have lost some locking capability and I would replace them. These nuts are a "stover" type locknut and may not be easy to find. The GM part number was 9422300 but it's long since GM-discontinued

AMK Products sells a repro of GM 9422300 nut. But they have a $30 minimum order.

Lief,
If you question the integrity of the bolts (or nuts) and are going to go through the effort to get access to the bolts - rather than re-use anything suggest you consider replacing the nuts and bolts - a set of 4 nuts & 4 bolts is less than $10. If those bolts were over torqued the bolt might have been stretched enough to contribute to the nuts working their way loose. Good early winter project...... don't you think!

Re: '67 Front Spindle Steering Arm Mount Nuts

Thanks everyone. I have the answers I need. I had already put the bolts and nuts in my cart from Zip...the cost of which is most likely less than the shipping will be I was hoping against hope that someone had a novel way of tightening a nut without being able to stabilize the bolt...I'm guessing no such luck.

SOMETHING caused those fasteners to become loose.

I would carefully disassemble that entire structure to determine root cause and what additional damage you may have.

More than bolts may need to be repaired/replaced.

Dave,
Thanks for the heads up. I will be looking over everything very carefully as I disassemble. BTW, what is the proper torque spec for this nut??

I do not have torque specifications for a 1967 suspension - should be in your Service/Shop Manual.

It's not. I've never found the torque value for those bolts in ANY C2 or C3 service manual. Since these were part of an assembly installed at St. Louis, there's no torque value in the AIM's either.

I recommend 65-70 ft/lbs for 1963-67 and 95-100 ft/ lbs for 1968-82.

Thanks Joe. I did not find it in my ST-12 or other service manual either.

Attached are torque values from 1980 Shop Manual.

Yes, I'm familiar with this. However, the torque for the bolts/nuts in question are not shown on this table.

Re: '67 Front Spindle Steering Arm Mount Nuts

Yeah, you really have to know if a given nut or bolt for 1980 is a different size or grade from the target year. For example, I think the steering knuckle bolts changed from 7/16” for 1963-1967 to 1/2” in 1968.

They did change for 1968-82. That's why I have different torque recommendations for 1963-67 versus 1968-82. The bolts and nuts for all are SAE grade 8.
