1. A chassis control arm for a wheel suspension, comprising:
a control arm body, a spring abutment and an actuator which is arranged between the control arm body and the spring abutment, wherein the actuator is configured to adjust a position of the spring abutment relative to the control arm body,
wherein the actuator includes a lifting gear which is configured as a movement thread, the lifting gear includes a lifting spindle of which the spring abutment is arranged thereon,
wherein the actuator further includes a housing which is cohesively attached to the control arm body,
wherein the actuator housing is made of a thermoplastic plastic material and the control arm body is made of a metallic material, and
wherein the cohesive attachment of the actuator housing to the control arm body is configured to be formed thereof by heating the control arm body to a melting temperature of the thermoplastic plastic material of the actuator housing and undergoing solidification.
