Technical Case hardened slotted nut source

What’s the key looking item about?

 

No idea. I just remember seeing this in the 3rd Gen catalog. Some how that must slide it to lock the outer nut to apply force to it. I'd ***ume it comes with directions.

 

Maybe put some weld on the nut to shrink it some?

 

I think this is the best possible solution if you're insistent on using that axle! Crank that nut on, say a prayer, get out the heavy sparkler and give it hell... One last time!

Well gents I think I got it licked. A buddy loaned me his thread file to clean up the threads and he gave a pair of new OEM axle nuts. Man these nuts are heavy duty. They are 1/4” wider than the repro ones I got from Third Gen Auto. In fact they cover all the exposed threads on end of the axle. I feel much more confident that hub will stay put.

So the actual suspect (yes axle threads are worn a bit) was the “nut”.

 

I'm glad you're confident with that repair... because I wouldn't be.
