Hi, Just purchased a 2019 Cherokee 234 VFK; have an issue and am looking for advice. When I towed it at slow speeds coming home, I noticed a loud squeak from somewhere behind me. Called the dealer, and was told I should use Silicon on the ball and arms of the sway hitch. ( and never use grease).
I did notice some of the chrome rubbed off the tow ball; any thing to that? What does every body use to lube their system?
