How to Clean Rusted Frame Weld Nuts to Install Trailer Hitch on 2013 Chevy Equinox
Question:
The welded nuts are rusted out can it be fixed or not
asked by: Larry J
Expert Reply:
The Draw-Tite # 36408 Class II hitch you referenced uses 4 M12x1.75 bolts to attach to the nuts welded into the frame. If they are corroded, and spraying them with a spray lubricant like PB Blaster and using a wire brush like one on a battery terminal cleaner like # DW00254 hasn't done the trick, you'll need to re-tap the threads. We offer a tap wrench set, part # PT22FR that includes an M12x1.75 tap. Before attempting to run the tap through the threads, be sure to hit each nut with a good shot of spray lubricant. Be sure that the tap runs through the threads perfectly straight and not an an angle.
