Application Details

Compatible with 2007-2012 Mazda CX-7, front left lower rearward.

What This Bushing Helps Address

• Excessive play in the control arm pivot point
• Clunking or knocking from worn suspension bushings
• Uneven suspension response at the front left lower rearward mount
• Loss of steering precision caused by deteriorated rubber bushings
• Vibration transfer from worn suspension isolation components

Installation Notes

Inspect the control arm and surrounding hardware before installation. Because mounting hardware is not included, reuse or replace related fasteners as needed based on the vehicle condition. Verify the front left lower rearward position and confirm dimensions against the original part before pressing the bushing into place.
