Cleaning Threaded Holes on a 2011 Kia Sorento to Install a Draw-Tite part # 75684  


What can I do to to mount trailer hitch to under carragiage frame do to corrosion to the threads in threads?


Expert Reply:

This is a fairly common problem when fitting a new trailer hitch on a vehicle that has seen a couple winters. Over time, your vehicles frame, in this case your 2011 Kia Sorento, will attract dirt, salt, road grime, etc. These materials will clog up the bolt holes in your cars frame and harden, causing rust and corrosion.

This is an easy fix with a wire brush such as the Deka Battery Post and Terminal Cleaner # DW00254 and spray lubricant. I have provided a link to our FAQ page on cleaning weld nuts to assist you as well as a link to a video showing you how to properly clean your bolt holes.
