**Non offset bushing kit, does not include retaining brackets** Worn control arm bushings produce many unwanted symptoms including vibrations at speed, shaking in the steering wheel, strange pulsing and vibration under heavy braking, and clunking noise over bumps or dips in the road. These control arm bushing isolate the lower control arms movement. After years of driving and countless of thousands of miles the rubber in the bushing eventually wears out and eventually cannot support the forces created by driving.
