trailer axle rebuild...
 

So, the spindle nut came off of one of my trailer axles and it stripped the threads on the spindle. The spindle itself looks ok, so I'm wondering if I can just cut new threads on it or do I need to 1) get a new axle or 2) grind/cut off the spindle and weld in another one?

Thanks,

I have a good axle rated 5000lbs with springs. i am in MD.

just going through a trailer axle rebuild myself. there are some great places that you can get parts and I have become an unofficial expert on trailer rebuilds. You can get the spindles seperate but you have to weld them onto your existing axles. The other option is taking the axle to a steel fabrication or welding shop where they can build up the metal that was ground off with a mig welder and then they can recut the threads. Your best bet is to just buy a whole new axle. If the shop can get the spindle plate back on perfectly the trailer will track to one side or the other and wear out your tires.

The trailer place suggested that I might be able to salvage the current threads, so I'll see if I can do that. I think about 20% of the threads are toast. A new axle (w/o hubs) is about $100. A new hub is $29 and I didn't get a quote on the spindle, but that is an option. I have an air grinder and a mig welder, so if I can't build up the spindle and recut the threads, then I might just take off the current spindle and weld in a new one.

for the amount of a new spindle just get a new one, better safe then sorry, you don't want to do the job twice!!

I'd figure a way to recut those threads, slap 'er back on and go!!...that nut doesn't even torque down tight, so there's no real pressure on those threads...w/80% still intact, plus what you'll get back chasin' 'em out again, there oughtta be PLENTY of holdin' power...

plus heck there's a keeper to hold the nut on and in place anyway.
