Yesterday, my steering wheel--the factory-installed "mahogany" wheel--began slipping on the steering shaft. Upon pulling the steering wheel, I was greeted by a pile of gray dust.
Evidently, the steering wheel nut had been working loose for some time now and this "looseness" has caused a grinding down of the groves inside the steering wheel. Except for the top 1/8", the grooves are pretty well worn smooth. The teeth on the steering shaft are in good shape, however.
At first glance, it appears that the damaged part is not replaceable/removable from the steering wheel. Therefore, I have:
-wirebrushed all the loose dust from what's left of the groves inside the wheel,
-placed the wheel back on the shaft,
-tapped it down as far as it would go so that the remaining 1/8" of groove would be grabbed by the shaft's teeth,
-twisted out the teeth of the lock washer and.
-torqued the steering nut down to about 5,000 lbs.
So far, it's holding OK, but this is not the permanent nor the safe solution. I'm afraid that it might break loose again and start spinning at an unfavorable time.
Has anyone else been faced with this problem? Short of buying a new steering wheel, do I have any other options? Can these groves be recut with some sort of carbide tool, similar to the way that the groves on the face of a golf club can be recut?
Any suggestions welcome. Feel free to contact me direct at the addresss below.
Many thanks for any suggestion you may offer,
