摘要： A stabilizer bar assembly includes a stabilizer bar having a bushing, a bushing retainer in mechanical compressive engagement with the bushing, and a mounting bracket adapted to connect the stabilizer bar to an automotive vehicle. The bushing retainer can have a uniform outer diameter such that the bushing is compressed uniformly over the entire length of the bushing retainer, or, alternatively, the bushing retainer can have a stepped outer diameter such that the bushing is compressed differently within discrete sections along the length of the bushing retainer. A method of inducing a pre-load onto a bushing that supports a stabilizer bar includes: providing a stabilizer bar, placing a bushing onto the stabilizer bar, placing a bushing retainer, having an first outer diameter onto the bushing, and reducing the outer diameter of the bushing retainer to a second diameter that is smaller than the first diameter.

摘要： A method is provided for manufacturing a catalytic converter. A metallic tubular member is provided. A section of the metallic tubular member is deformed radially inward to form a neck portion. The neck portion has a diameter less than an initial diameter of the metallic tubular member. The tubular member is separated at substantially an axial midpoint of the neck portion for obtaining a first pre-form member having a first conical-shaped end. At least one catalytic element is inserted in the first pre-form member. An outer surface of the first pre-form member is deformed radially inward for securing the catalytic element within the first pre-form member. The first pre-form member is spin-formed for forming a second conical-shaped end opposite the first conical-shaped end.
