Abstract
A spring and strut module for an automotive vehicle includes an extensible and contractable strut adapted to be secured to a rigid frame of the vehicle by a strut mount, and a spring unit including a spring for resisting retraction of the strut. A bearing and upper spring seat assembly includes an upper spring seat for the spring and an annular bearing for the spring seat. A bearing base is formed integrally with the spring seat and supports the lower race. A bearing cap covers the upper race. The bearing cap provides a seat for the strut mount. The spring seat is made of a plastic, preferably glass fiber reinforced Nylon. The bearing base has drain holes for carrying away any possible foreign matter. The spring seat has an annular upwardly opening trough, and the strut has an annular downturned lip extending into the trough providing a labyrinth seal inhibiting the entry of foreign matter into the bearing. The bearing base and bearing cap have overlapping portions also for the purpose of inhibiting entry of foreign matter into the bearing.
