I put a Curt class I hitch on my WRX for a bike rack.
Unfortunately the existing machine thread fasteners were tired and we stripped the threads in one weld nut, which is not good.
The Curt hitch has but 2 fasteners on each side so I want to repair it, but there's no access to the interior of the frame rail so what corrective options exist?
1. drill/tap larger size
2. Helicoil new threads
3. pull bumper off to put a new nut into the interior of the frame rails?
