Hey Jimmy, did the replacement hardware kit work out for your Odyssey’s hitch? Knowing how it fit could help others who run into the same issue with broken weld nuts.

@JamesonC Yes! Thank you for reaching back out. I needed a flexible magnet to get the broken weld nuts out but once removed, the plate and carriage bolt worked perfectly and have been used for about a year now with no problems. Only point to remember is the torque spec is different for bolts in the weld but versus the carriage bolt.

Hello Josh, thanks for reaching out. Sorry to hear the weld nuts broke, that is never fun. The Curt #C13068 hitch for the 2021 Honda uses 7/16" grade 8 bolts. The spacer should be a 1/4" x 7/8" x 2-1/4" square-hole spacer. The…

Answer 6

The weld nuts were probably still dirty, when you were installing the hitch which caused the weld nut to brake off when putting torque on it. If you have not already installed the other bolts, you will want to clean them out with WD-40 and wire brush…

Yes, it sounds like you broke something. Specifically one of the weldnuts that are on the inside of your 2019 Honda Odyssey's frame for the trailer hitch's bolts to thread into. It's annoying but not really a huge problem. Although…
