How to Clean Nuts Welded into Frame of 2011 Kia Sorento to Install Trailer Hitch


Hi, I was going to install the trailer on my 2011 Kia Sorento but the threaded holes on the underside of the vehicle are dirty/rusty. Ive already tried cleaning with a wire brush and have had minimal success. Can I buy an M10 tap for the threaded holes and retap them to make the threads usable? Any help would be much appreciated! Cheers, Cameron

Absolutely. If the wire brush and WD-40 treatment didn't work, brake out the big guns and hit that frame mounted weld nut with a M10 x 1.25 thread tap. Be sure to spray a generous amount of WD-40 or other spray lubricant up into the weld nuts before using the thread tap.
