Rear Axle Spindle Threads

Post by captain marty » January 30th, 2017, 12:07 pm

My spindle threads are almost not there.
I'm trying to find what I can do, without taking it all apart to replace them.
Can I have the threads built up and threaded or cut down and threaded using a smaller castle nut?
What else might I think about before rushing into something wrong?

The threads are mostly worn off. I will meet with a tool maker tomorrow and see if he can cut them down to 14mm x 1.5.
Man I sure don't want to take the rearend out again.

According to the parts book the nut is 7/8-14, you might try something like 20mm.

How did you make out on the axle threads? One other thought would be to try and tighten enough to get the carter pin in and tack weld in a couple spots to keep it in place.

I went to a taller castle nut, which covers more of the thread and torqued it to almost 100 FP.
I will drive this truck sometime in the near future.

I am glad you have the axle threads situation under control. If it ever causes you problems in the future, you might consider checking with a mobile axle repair guy. You can usually find them by checking with a large truck or trailer repair facility (not the kind where nobody has any grease on their boots) or a large truck towing service. The ones I have been able to use are usually retired Navy machinists (very knowledgeable and very resourceful) who travel in a van or truck going from one job to another repairing big rig axle ends that have either spun a wheel bearing or had the bearing nut back out allowing the hub, wheels, and axle shaft make a mess of the end of the axle housing on the way out. The one who saved my motorhome housing was happy as could be because I had the motorhome towed off the shoulder of the road and he did not have to work in mud. Hope you never need this but if you do, you now know these guys exist.
