This lawn mower repair guide gives step-by-step instructions for how to replace a lawn mower wheel. Lawn mower wheels can wear out with normal use. Fortunately, replacing a wheel is an easy repair. Before ordering the replacement lawn mower wheel, also check the axle shafts for wear and damage. Replace worn axle shafts at the same time to prevent the new wheels from wearing prematurely. Replace the wheels and axle shaft using the manufacturer-approved replacement parts.
