Hand trucks are convenient when moving heavy boxes or objects. Most hand trucks now come with pneumatic wheels instead of solid rubber. These wheels often need replacement. The end of each axle has a wheel end cap that protects the end of the axle and covers the retaining ring or clip that secures the wheel. These end caps are usually made from plastic and develop cracks or break. Replacing the wheel end cap on a hand truck requires obtaining another that matches.
First, see if you can locate a notch between the outside of the end cap and the face of the wheel. Wheel end caps simply snap on and off the end of the axle. Insert a flat-head screwdriver in the notch and pry the end cap off the wheel and axle.
Grasp the sides of the end cap with a pair of pliers if you do not find a notch or the end cap is a button-type cap. Twist the end cap left to right with the pliers while pulling it away from the axle.
Take the end cap to a rental tool shop or an authorized dealer for your brand of hand truck. This ensures that you purchase replacements that match your unit.
Position the new end cap over the axle and center of the wheel. Push the end cap over the axle until it snaps into position. If more pressure is required, take a piece of cardboard or piece of wood and position it against the end cap. Then take a hammer and gently tap against it to snap the end cap into place.
