Bushings are designed to wear out sooner than the mating parts. They are made of softer material and are expendable. It is recommended that anytime the jack is torn down to a point where the bushings are accessible, that they should be replaced. This will ensure longer life of the jack and will reduce the amount of downtime. Bushings are very inexpensive and it is cost-effective to change them regularly.
Tip:If bushings are cracked, broken, egg shaped or worn more than 1/16" from the original size, replace them.
Remember, if the jack is already disassembled, replace all accessible bushings.
Tip: Coating axles and bushings with anti-seize compound before installation makes maintenance easier.
