Recalculating Ball
used on many trucks and SUVs
linkage that turns the wheels

Inside the gear boxWorm gearthreads are filled with 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

Power Rack & Piniontwo 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.

Steer by WireSensors 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

Idler armsBy replacing worn
idler arms you can reduce vehicle wander, excessive play in the steering wheel and abnormal tire wear.

Idler Arms
Idler Arms hold the steering linkage in place.

Ball Joints
Ball Joints are the pivot points on which the front wheels turn. By replacing worn ball joints with Ball Joints, you can reduce front-end noise, looseness and tire wear.
