Why do my lawnmower wheels wobble?

As lawnmowers get used, eventually the hard plastic housing on the wheel hub will wear against the axle bolt and start to “wobble”. A quick fix for this is to install a bushing into the wheel. This is done by removing the “wobbly” wheel form the mower and drilling out the axle bolt hole in the wheel from a wobbly 1/2″ to a new 5/8″ ID (inside diameter) hole.¬†Then purchase a nylon bushing with a 1/2″ ID and a 5/8″ inches OD (outside diameter) and tap this bushing into your newly enlarged axle hole.

The nylon material of the new bushing will give the wheel new strength and longer life.
