How do I remove rust from threaded hitch holes in a box frame? Answered
I have a 2002 Jeep Liberty and the correct hitch and mounting hardware (bolts and washers). Unfortunately, the holes in the frame are very rusted from the 8 years of driving without a hitch. I can't even get the bolts to seat properly. I checked and made sure that they are the right bolts for the vehicle. I tried a thread cleaner kit from a local garage but wasn't able to make any progress. Soaked the holes with WD-40 but still no luck. I can't put a nut and washer on the other side because it's a box frame. I'm debating using a brass bristle brush on a drill to try to clean it out but that could ruin the threads. Any ideas?
