Ours are air assist. If the pins don't retract it means either the release valve or air bag is bad. In both cases it's a shop fix and no amount of hammering or curbs or whatever will help.

Look and see if the spring needs hooked back in from underneath. I had to do it plenty of times on cfi's trailers.
Or you can take it to the shop and they can take three days to get to you to do it.

If they're rusted, beat the rails in multiple spots with something heavy to break the bond. Then you can hit them up with a lubricant. I've heard grease and oil based lubricants can attract dirt and grime, which can make it hard to slide again. I've also heard of people using dish soap, which can be reapplied after it washes away. Get some wheel chocks to carry with you, since there may not always be a suitable curb available to use.

I use that lubricant stuff u get at the truck stop it's called BLASTER ..comes in a pressurized spray bottle..spray it in all the holes on the tandem, let it soak a minute..if u have to get your mallet and beat moderately on the slide
.usually always worksTrucker61016, Rideandrepair, truckdriver31 and 1 other person Thank this. -
Just for future reference make sure you have the system fully charged before attempting to slide the air assisted pins or they don't like to release

A couple 4x4's might do it.Trucker61016, Team818, bryan21384 and 2 others Thank this. -
pull handle as far as you can. put a pair of vice grips on and lock them as closes as you can to the rail. get in truck and wiggle it back and fourth

After the pins are fully retracted, get rolling a little, then quickly pull down on the trailer brake handle, don’t be slipping the clutch.

Here are the tricks:
1. Hammer
2. Curb
3. Rock the trailer with short sharp acceleration forward, then backward. Important to try both directions.
4. Make sure your automatic slack adjusters are adjusted by fully pumping the break pedal down several times.
5. Try a different spot, if the ground isn’t perfectly level, the tandems can sometimes refuse to slideTrucker61016, TravR1, Team818 and 5 others Thank this.
