A quarter car vehicle suspension including a wheel, a bearing having an axis of rotation, a quarter car steer axis about which the wheel steers, a strut with a piston rod and a piston rod axis, the piston rod axis aligned at an acute angle with respect to the quarter car steer axis, and a spring seat, wherein the bearing is mounted between the spring seat and the vehicle body, and wherein the axis or rotation of the bearing is substantially aligned with the quarter car steer axis and at an acute angle to the piston rod axis.

Strut assembly with bearing axis alignment

An air spring module is constructed and arranged to be removably mounted between a damper and a vehicular body. The module includes a bored contact piston which is slip fitted over a reciprocable piston rod of the damper. A retaining ring releasably locks the contact piston to the damper, and O-ring seals provide a seal between the contact piston and the damper. An air sleeve is secured at its lower end to the contact piston and is secured at its upper end to a canister. A bearing assembly and mount rotationally and removably secures the canister to the body.
