Abstract
A lift apparatus is provided for use with a vehicle comprising a first frame and a second frame. The lift apparatus comprises a spindle, a bearing, a cylinder, a snap ring, and a bearing retainer. The spindle is configured to be attached to the second frame so as to extend therefrom in spaced apart relation to the first frame. The bearing is positioned on the spindle. The cylinder is configured to be attached to the first frame and is attached to the second frame to move the first frame relative to the second frame. The cylinder is positioned on the bearing such that the bearing enables movement between the spindle and the cylinder. The snap ring is attached to the spindle. The bearing retainer is positioned on the spindle between the snap ring, and the bearing retains the bearing on the spindle.
