Is there anyone in the Topeka, (or Kansas City) area that can repair or replace a damaged spindle on a torsion axle?
The trailer is actually a Haulmark enclosed race trailer with tandem 3500# axles, but the axles look to be the same as some boat trailers.
Any suggestions?

Buy a new axle from a trailer supplier. They arent that expensive. I bought one for my race trailer a few years ago. If you go the repair route....PRAY you dont have some kinda accident where someone dies. The insurance company will have a field day with a repaired axle.

Depending on the build, repair may not be an option.

True dat!!!!

keep em greased and you wont have a problem

Depending on the axle type you can either change out the "axle end" which is the entire torsion set up on the axle or, yes replace the entire axle. Both options are pretty easy.
