It looke to me than unlike an 80 spindle it does not separate from the knuckle? is this correct? I guess I'd try to file some threads back into it. Cut one or more of the locknuts in half. place further back where threads are good and chase the treads from good to bad. Maybe hoseclamp the two halfs together.
Also on the photo's if you are further away guess 3-4' and zoom in it works better.:popcorn:

Yea, the spindle is a fixed part of the knuckle. The original locknuts are totally trashed. I have to wait until Wednesday or Thursday for the replacements and I don't want to cut them in half.

After bar-hopping with my woes in Monroe County FL tonight, I understand that I can buy thread dies that clamp around the spindle at Napa on Monday. Does anyone know the number of threads per inch on the steering knuckle? I doubt I have the patience to hand file all of that crap out of the threads. That is wicked old school talk there.

If I do have to buy a new knuckle...is my only option stock or is there a mod?

Thanks for the photography advice. I'll give it another go in the morning. Thankfully, I noticed this in my garage and not on a trail somewhere. Funny thing is, the only symptom was a loose wheel bearing. It would have probably gone a lot farther.
 
I'm wondering if somehow the outer nut backed off and spun with the hub against the spindle? Yeah, the nuts aren't thick enough to cut in half. And I would be impressed if NAPA has a die that large, but who knows.
 
Travis, ur a dick. U could have started ur own thread, but nooo, u had to hijack one, and from a nice guy nonetheless.
My advice is bulk out the metal with a flat file or even an angle grinder and then get on that puppy with a thread file. I have a set here, just stop by and pick them up, or better yet, just go to Grainger and get your own set. Put it on my account (no, not really).
Good luck, thats pretty bogus. Glad to hear you fell off the wagon tho, I guess we won't see you at the Bill W meeting next week?

Ha! I didn't really know what I was getting into and Tom's thread needed some pics anyway. It's a year old...so I doubt that I hurt his feelings.

Stopping by Orlando isn't really an option at the moment, but your generosity is un-matched. Come to think of it now would be a great time for you to take that vacation in the Keys. Skilled wrenchers with tools not only get free room and board, but free beer too.

Thanks to Farnam for the photography advice. Below, you can see what's left of the lock nut.

I would start with a hacksaw blad and work that in on the threads that are screwed up the most. Then proceed with a file and work that around the threads that are damaged. take it slow and drink lots of beer. Slowly work around it until you think you have it cleaned up. Did you order atleast one extra hub nut? I would worry that one might get a little chewed up when you are chasing the threads. you could also file down the last three threads or so on the spindle so that the nut starts off a little further back.

Take it slow and you'll get them to work. for the file, use either a thread file or a triangular file...

Getting there dude! Another hour or so of filing and the new nuts later on this week, I might have my truck back. They only had two in stock, so that's all I ordered.

FWIW The thread size is 1.5 on the metric file.

Hot damn Trav! That actually looks really good compared to what it was. Dont sweat it, just take it slow like they said above and you'll be rolling hundy-style by the weekend!
 
After my new nuts came in and a few more hours of filing, I am proud to say that we are rolling 100 style once again. That thread work was a very tedious job. I wouldn't wish that on my worst enemy.

I had a slightly different experience with adjusting the bearing pre-load than those in the FAQ. At 43 ft lbs on the adjusting nut, I was able to spin the wheel. (About 7lbs on the fish scale.) I tightened it further until I got about 12 lbs on the fish scale, then lock washered, lock nutted and re-assembled the rest.

I used mobile 1 synthetic bearing grease with the old bearings and races, which were still in good shape.
