5 Conventional Steering AA Pitman Arm BB Gear Box CC Center Link DD Idler Arm EE Tie Rods
6 Recalculating Ball used on many trucks and SUVs linkage that turns the wheels
7 Inside the gear box Worm gear threads are filled with ball bearings ball bearings recirculate through the gear as it turns. without the balls in the steering gear, the teeth would come out of contact with each other for a moment, making the steering wheel feel loose Seal
12 Power Rack & Pinion two fluid ports, one on either side of the piston. Supplying higher- pressure fluid to one side of the piston forces the piston to move, which in turn moves the rack, providing the power assist.
14 Steer by Wire Sensors pick up the driver's steering inputs and send this information to two microcomputers which, in turn, control an electrically driven steering gear. completely eliminate the mechanical connection between the steering wheel and the steering
15 Idler arms By replacing worn idler arms you can reduce vehicle wander, excessive play in the steering wheel and abnormal tire wear.
16 Idler Arms Idler Arms hold the steering linkage in place.
