Stripped Spindle Thread Help

[Tony]

I have a 1979 Chev K10 with front wheel locking hubs.

The locknut and spindle thread (at the outer edge) has been partially
stripped. The thread that is not damaged is still usable. I cannot
remove the inner adjusting not because of the stripped portion. I have
tried to grind the stripped thread away (protecting the good thread by
undoing the adjusting nut up to the stripped thread) using carbide
grinding bits. All I have achieved is destroying the bits and polishing
the stripped thread.

I cannot use a steel file because the access is limited.

How can I remove the stripped thread? I believe the spindle is forged
steel. I have contemplated using a cold steel chisel, but do not want
to attempt until I have more info on possible solutions.
Hoping someone can help
Regards
Tony

Die grinder. Dremel if necessary.

Have you tried an angle grinder? I have a 4 and 1/2" DeWalt I got from home
depot for $40. They have the grinding wheels pretty cheap. I've been able to
grind anything I want with it.

Be careful with grinding threads, you may end up unable to pass a nut onto
the threads after you are done grinding b/c of the burr created by the
grinding.

If THAT fails, I would drill a hole in the middle of the spindle (as deep as
the bad thread goes). Start with a small bit and work up. I would continue
to move up in bit sizes untill the edges are small enough to grind.

HTH, plz let us know what works!

Tks for the advice. Angle grinder is a problem, no space. I will post
the results.
