castle nut size and threads

[Mator]

While repackaging wheel bearings I noticed the threads on the castle nut are shot and I need to replace it. The local parts stores don't carry them and they don't the size or thread size. Can any one help. I want to get a die to chase the threads and a source for getting a new one. Thanks

Sorry it was supposed to say re-packing.

It should be pretty easy to get a new one. Dorman probably has a replacement. I would try RockAuto.com

I would think any front-end shop would have an old coffee can full of them.

1/2 ton? 3/4"-20
Very common Chevy castle nut. Not so common thread, you won't find a die unless you get the spindle rethreading set avail. I don't remember if I bought my die set at Harbor Freight or maybe online, it's a set of dies for all the spindle threads normally used.
Pretty much all Chevy cars and light trucks use the 3/4"-20 nuts, pre-metric.
Dorman 615-065

Thanks guys,
Thats pretty much what I thought. I found a castle nut but will have to order a die. The threads are pretty goobered up and I can get the new nut back on.

These nuts should be grade 8 hardware and the stuff you get from most parts stores today are grade 3 and worse, made in china.

You won't find a 3/4-20 castle nut any where but from a auto parts store. Dorman are correct castle nuts.
