How to Replace Motorcycle Shock Bushings

Updated April 17, 2017

Motorcycle shock bushings form the connection between the shock and the motorcycle frame. They absorb and isolate the vibration and shock caused by the road surface. Good shock bushings are crucial for maintaining control over the rear wheel and swing arm. Symptoms of worn bushings include: skipping or hopping of the rear wheel under power or braking, the rear end feeling squirrelly in corners and the bike feeling unstable in general.

Jack the bike up with the bike lift. Position the lift towards the rear of the frame so that the rear wheel is lifted clear of the ground. Block the rear wheel up slightly to relieve the pressure on the shock ends.

Remove the shock stud nuts, with a wrench, from their studs on the frame and the swing arm. Slide the shock off both studs at the same time.

Push the old shock bushings out of the shock ends. Push them out with the butt of the ratchet handle or a large drift punch. Inspect the shock ends for cracks or damage and clean the inside of the shock ends with a small wire brush.

Lubricate the rubber bushings with a little soapy water. The fit between the bushing and the shock end can be quite tight. Push a bushing into each shock end, centring the rubber in the eye at the end of each shock.

Slide the shocks back onto their mounting studs. Install the shock stud nuts and torque them to factory specifications for your make and model. Unblock the rear tire and set the bike down.
