The front suspension of the Morris Minor was built to last a lifetime, but neglect and abuse can shorten it with disasterous results. The main structure of the suspension is the swivel pin; it holds the upper and lower trunnions, steering arm and the hub bearings. When the trunnions are not properly maintained (greased) they wear on the treads of the swivel. When the wheel bearings are not maintained they will wear out the stub axle sticking out of the swivel. If yours need replacing, SUS133 is the right side, SUS134 is the left.
