An assembly comprising:
- a bush housing comprising a bush-receiving bore;
- and
- a bush received in the bush-receiving bore, the bush comprising an internal surface and an external surface;
- wherein the internal surface defines a bore and is configured to support movement of a body received in the bore;
- wherein the external surface defines an outer radius;
- wherein the external surface comprises one or more recesses disposed axially within the bush-receiving bore;
- and
- wherein the bush housing is plastically deformed in the locality of the one or more recesses and the plastically deformed material thereby engages the one or more recesses to retain the bush in the bush-receiving bore.

A method of inserting a bush into a bush housing, the method comprising the steps of:
- i) aligning the bush with a bush-receiving bore of the bush housing;
- ii) urging the bush into the bush-receiving bore such that one or more recesses in an external surface of the bush are disposed within the bush-receiving bore;
- and
- iii) applying a compressive force to compress the bush housing such that the bush housing is plastically deformed in the locality of the one or more recesses and the plastically deformed material thereby engages the one or more recesses.
1 more element
An assembly comprising a bush received in a bush-receiving bore of a bush housing, the assembly being obtained by the method of:
- i) aligning the bush with the bush-receiving bore;
- ii) urging the bush into the bush-receiving bore such that one or more recesses in an external surface of the bush are disposed within the bush-receiving bore;
- and
- iii) applying a compressive force to compress the bush housing such that the bush housing is plastically deformed in the locality of the one or more recesses and the plastically deformed material thereby engages the one or more recesses;
- wherein the bush housing comprises one or more indentations in an external surface of the bush housing, the one or more indentations being formed during step (iii).
