Hydraulic damper for a mount assembly

A hydraulic damper for a mount assembly, the hydraulic damper comprising:

• a housing defining a cavity, the housing integrally formed to include a plurality of retention features and a step;
• and
• a subassembly at least partially disposed in the cavity and secured relative to the housing by the plurality of retention features, the subassembly including a washer, an inertia track circumferentially surrounding the washer, a compliance member circumferentially surrounding the inertia track, the compliance member being elastically deformable in the radial direction, and a rigid outer sidewall having an upper end and a lower end, the rigid outer sidewall bonded to the compliance member;
• wherein at least one of the plurality of retention features and the subassembly is elastically deformable in a radial direction from an initial diameter to an elastically deformed diameter such that the subassembly is sized to axially pass by the plurality of retention features for insertion of the subassembly into the housing, wherein the lower end of the rigid outer sidewall of the subassembly is adjacent to the step and the plurality of retention features radially extend over the upper end of the rigid outer sidewall of the subassembly to secure the subassembly relative to the housing.
