How to Remove Damaged Lug Nuts on a Trailer

When a trailer lug nut is damaged, it usually means its threads have been stripped. A damaged lug nut can be very difficult to remove and may require varying methods before it finally comes off. Another factor is the type of lug nut that is damaged. Many trailers have locking lug nuts for security purposes. A locking lug nut is smooth on the outside and can't be removed with a standard lug nut wrench. A damaged locking lug nut also can't be removed the normal way with a socket that fits inside of it.

Instructions

  1. Standard Nuts

    • 1

      Soak the lug nut with a penetrating oil. This is particularly effective if you are under no time constraints. Allow the oil to seep into the nut for as long as possible. Remove the lug nut with a lug wrench.

    • 2

      Use a different wrench. Many lug wrenches are shaped like an "L.'' Try using a four-way lug wrench, which provides a lot more leverage, or torque. Apply pressure to the left side of the four-way wrench with your foot, and pull up on the right side.

    • 3

      Remove the lug nut with an air gun.

    • 4

      Heat the lug nut with a propane torch. Heat only the nut. Don't heat parts around the nut because this can cause structural damage or weakening to other parts of the wheel. Loosen the nut with a lug nut wrench or air gun.

    • 5

      Break the lug nut with a nut splitter. A nut splitter splits a nut in half when it is attached to the nut and tightened. A split nut will fall apart.

    • 6

      Burn through the entire nut with a torch when all else fails. This method should only be used as a last resort because it will be easy to damage the wheel stud.

    Locking Nuts I

    • 7

      Place a socket over the nut.

    • 8

      Hammer the socket onto the nut with a rubber mallet.

    • 9

      Place a power bar into the socket.

    • 10

      Remove the nut by turning the power bar.

    Locking Nuts II

    • 11

      Place Vice-Grip locking pliers on the lug nut.

    • 12

      Hammer the Vice-Grips in the direction that removes the nut.

    • 13

      Remove the lug nut with a lug wrench if the Vice-Grip pliers have only loosened it.
