Due to the physicality of bike riding, bicycles can experience a lot of wear and tear over a short period of time. To keep yourself safe while riding a bike, it is important to stay on top of your bike maintenance. Riding a bike with a bent or damaged bike axle, also known as a "skewer," will cause your wheel to rotate unevenly. Fortunately, you can replace a bike axle in a few easy to follow steps.
Release the quick-release lever. On the end of the axle or "skewer" of your bike is a lever known as the "quick release lever." This lever allows you to quickly remove components from your bike wheel and also access your axle. Locate the lever on the end of your bike's wheel axle and turn it counterclockwise to loosen it.
Unscrew the axle cap. The axle cap is located on the other side of the axle, opposite the quick release lever side. Use your hands or a wrench to unscrew the axle cap until it releases the threads from the axle.
Clean the axle. If your axle is not bent and simply needs cleaning, take a clean rag and some water and then rub any dirt or grime off.
Replace your axle. If your axle is bent you will need to replace it. Remove the damaged axle and slide the replacement axle into the wheel. Then, screw on the axle cap and tighten it with your wrench. Next, tighten the quick release lever by turning it clockwise.
