These polyurethane front lower control arm bushings will also replace the original rubber bushings on the 03-09 Prius and the 00-05 Rav4. As the original bushings wear down the alignement angles of your front wheels will change and cause uneven tire wear, steering wander, and reduce your traction during a turn.
Hollowed Out Control Arm Bushings
Rubber control arm bushings do a great job of absorbing vibration between the road and the cabin of your Toyota, but they do this by flexing and bending. Over time, as the rubber continually bends, it's shape changes during suspension movement and the bushing will begin to form gaps and hollow out. These gaps make the control arm loose and can cause changes in the alignment angles of the front wheels.
The Importance of Alignment
If the camber angle, or tilt, of your front wheels is not held correctly then your tires are riding on their edge instead of flat against the road. When this happens one side of your tires will wear down unevenly meaning early replacement. Besides this thrown off camber angles can affect how well your front tires maintain traction during a turn. This is important whether you enjoy taking Erath County backroads at speed or have a windy path to the school drop-off.
Polyurethane is a more durable material than rubber and will hold the alignment of your vehicle more securely. Not only this but heat, motor chemicals, and road salts can degrade rubber to the point that it can crack and fall apart, but polyurethane bushings hold your wheel alignment through even rough suspension movement. These bushings are backed by SuperPro's exceptional lifetime warranty that covers racing and off-road applications, and Suspension.com will handle any warranty issues for you in house.
