WP Lower Shock Threaded Bushing

It's a press fit/knurl. It needs to be pressed out from the opposite side.

Can you use a bearing puller on a slide hanmer?

Mine came out pretty easy, you might be able to tap it out with little force and not damage anything. Also might be able to rig together some type of puller with a deep socket, long bolt, and a nut/washer on the back side of the bushing (slightly smaller than the bushing) Almost like pulling a swing arm bearing

Push it out with an arbor press and appropriate support. It should come out pretty easily.

Tap it out gently.....those aren't that tightly pressed in.
