  Suspension Component Failure, Power Steering System Malfunction, Chassis Alignment Deviation, NVH (Noise, Vibration, Harshness) Fault, Bushings and Ball Joint Wear, Diagnostic Overview The System: The suspension system handles vehicle weight and absorbs road impacts, while the steering system provides directional control. They are physically linked; a failure in one (like a bent control arm) will immediately cause an issue in the other (like a crooked steering wheel). The Problem: Premature wear is often caused by heavy payloads, frequent driving on rough roads, or poor factory quality of rubber bushings and ball joint seals. Common Failure Points Control Arm Bushings: These rubber mounts allow the suspension to pivot. If the rubber cracks or tears, you will hear a "clunk" when hitting bumps or braking. Tie Rod Ends: These connect the steering rack to the wheels. When they wear out, the steering feels "loose" or "vague," and the front tires will wea...
