A power actuator assembly for a steering column assembly is provided. The power actuator assembly include an electric motor. Also included is a leadscrew. Further included is a gear arrangement operatively coupled to the electric motor, the gear arrangement driving rotation of the leadscrew. Yet further included is a nut threaded to the leadscrew, rotation of the leadscrew actuating linear motion of the nut relative to the leadscrew, the nut operatively coupled to a moveable portion of the steering column assembly to actuate motion of the moveable portion. Also included is a leadscrew housing, the leadscrew extending axially through the leadscrew housing. Further included is a helical bushing disposed between a radially inner surface of the leadscrew housing and a radially outer surface of the leadscrew.
