    Lubricating 5th wheel Hitch Jaws

    I had trouble getting my hitch to unlock at a recent trip so a generous dose of WD40 and 50 miles down the road did the trick. But I know that WD40 might have worked for the emergency but don't believe it's best for long term.
    What does anyone else out there use on hitch jaws that not only keeps the jaws working but doesn't gum up and attract dirt?
    My hitch is a Curt A16

    I had a Curt Q24 and it had numerous zerk fittings, I used Lucas Oil Red N Tacky, does your hitch not have zerk fittings?

    Any time i had trouble unhitching was more operator error than anything else.

    After you park and set the chocks, place the truck in neutral, let off brake, then back in park. Jaws should unlock easy after that.

    I followed the manufacture maintenance recommendation. For our it is WD 40 at specific points and grease on specific parts.

    I use Dupont teflon dry spray. WD40 works also but makes a mess after you apply many applications over time.

    I use marine grease on my hitch jaws.. but as stated above, put in neutral and take pressure off the jaws when you park it before unhooking.

    One more for using the Lucas Red and Tacky in the Zerk fitting.

    Totally agree with the necessity of taking the pressure off the hitch before pulling the handle. Chock first!! I know everybody knows that, but i always like to repeat it; one of the cardinal rules.

    I found with my PullRite if I put chocks behind the trailer wheels, put the truck in reverse, set the E-brake that was enough to take the pressure off the jaws to release. . . . . .
