Air chisel and hammer bit
When the ball mount on your
trailer hitch is rusted in
place, don't whack at it with a sledgehammer.
Here's what to do instead.
Buy a can of CRC Freeze Off penetrating
spray and an air chisel fitted
with a “hammer bit.” The air chisel
will run about $15 and the extra bit
will be about $8. Spray the opening to
the hitch receiver. This newest style of
penetrating fluid chills the metal,
causing it to contract to help break
the rust seal. Then use an air chisel
fitted with a hammer bit to
knock everything loose. The air hammer
will break up the rust, spread the
penetrant and free up the ball
mount. Once it's free, just tap
the rusted ball mount out
with a hammer. If
you plan to reuse
the rusty mount,
coat it with a rust
converter or waterproof
