1. A suspension, comprising:
- a damping assembly;
first spring seat means operatively associated with said damping assembly forming a first seating surface which is continuous and extends around said damping assembly;
second spring seat means operatively associated with said damping assembly forming a second seating surface which is continuous and extends around said damping assembly in an opposed parallel relationship with said first seating surface;
a tubular, sealed elastomeric spring having two ends which are operatively associated with said first seating surface and said second seating surface to form two continuous seals therebetween, respectively;
first anti-tampering means acting between said first spring seat means and one end of said spring;
second anti-tampering means acting between said second spring seat means and the other end of said spring;
bearing means acting between said second spring seat means and said cylinder, and including a load bearing member and a thrust bearing member;
said load bearing member being movable with respect to said damping assembly and projecting away from said other end in an outward direction;
said thrust bearing member being secured to and projecting outwardly from said damping assembly in parallel underlying relation with said load bearing member; and
third anti-tampering means acting between said load bearing member and said thrust bearing member;
said first anti-tampering means being breakable in response to tampering with the seal formed between said first seating surface and said one end;
said second anti-tampering means being breakable in response to tampering with the seal formed between said second seating surface and said other end; and
said third anti-tampering means being breakable in response to tampering with said spring and said first and second spring seat means.

Abstract
The system includes a hydraulically damped strut and a tubular elastomeric spring. The ends of the spring may be sealed so that the spring can be pressurized internally. An improved bearing, which permits rotative shifting of the spring and strut in response to turning effort, also is disclosed. The suspension is particularly useful in applications which heretofore involved MacPherson struts.
