    I could not get the pins in my 5th wheel in by pressing the "air slide" button on my truck, so i beat them in with a hammer. Now i cannot get the pins on my 5th wheel to pop back out.

    What force makes the pins on the 5th wheel to pop out? Is it air or what?

    How can i get the pins on my 5th wheel to pop back out?

    Air to retract, springs to push back out.
    Personally I find it easier to pull away from the trailer, operate the slide pin release, then move the fifth exactly where I want it using a pry bar.

    Spray with WD-40 deep into the pin area. Work the toggle switch back and forth. Check both sides, see if either is going in and out. Sometimes might catch on the lip and you can put a screwdriver in the hole and move the pin up and it will pop out. Coated with lube and working switch should get em out. Might have to slide a little forward or back if not lined up, but if one side is popping out u should be lived up.

    fluid film works the best you got to get everything free up. If you want it to work you got to take care of it. Every moving part must be lubed.

    What happened is that the pins would not pop out because they were not lined up with any holes. I did not know that the 5th wheel would slide better if I dumped the air out of the air bags. I called breakdown at my company. Breakdown told me to dump the air out of the air bags before I attempt to slide the 5th wheel. Lo and behold, it worked. I slide the 5th wheel and the pins popped right out. I have 7 years of experience. I used to be a trainer, but I did not know to dump the air out of the air bags when I slide the 5th wheel until a few days ago. Sliding the 5th wheel was always a very violent process before that.

    Oh by the way you use brass to tap on pins, either a brass mallet or a brass drift, but never steel on steel you will (or did) mushroom the pin.

    Back to a trainer can only teach what they know. So if you were not trained then you would not know.... But now you know.

    I never had to slide the 5th wheel when I was with a trainer. About my 2nd week solo, picked up a load that had me at 79400 gross. Had to slide my 5th wheel. I got on YouTube and watched a couple of videos! That's how I learned. And, even though it took my 5 reweighs, I did get myself legal with that load!
