What is a common cause of premature control arm bushing failure?

A common cause of premature control arm bushing failure is contamination from oil, grease, or other fluids. Control arm bushings are typically made of rubber or polyurethane, and these materials can degrade when exposed to certain chemicals. Leaks from nearby components, such as the engine, transmission, or power steering system, can drip onto the control arm bushings and cause them to swell, soften, and crack. This degradation reduces the bushing's ability to absorb vibrations and impacts, leading to premature wear and eventual failure. Improper installation, such as over-tightening the control arm bolts, can also damage the bushings and shorten their lifespan. The chemical breakdown of the bushing material is a primary factor in accelerated wear.
