This is a great product for those who want to continue using stock suspension components. A leaking OEM bushing can be removed with simple tools like a steak. a knife to cut through the rubber (with a small amount of silicone gel coming out, the knife will help cut through the OEM rubber sleeve), then a hacksaw to cut through the remaining steel sleeve. The Energy Suspension Poly sleeve is easy to insert because it's designed that way. The radius rod moves in a rotational arc, and the Energy Suspension sleeve is designed to allow for this rotation. Many other replacement products fail and fail, but this energy suspension product looks set to last the extended life of the vehicle.
