* Visual Inspection: Look for obvious signs of damage like cracks, bends, or rust. Severe rust can weaken the metal to the point of failure.
* Ball Joint Issues: The ball joint connects the control arm to the steering knuckle. If the ball joint is worn, loose, or makes clicking or popping noises, it usually indicates a problem with the entire control arm assembly (though sometimes only the ball joint needs replacing). Excessive play or movement in the ball joint is a serious safety hazard.
* Bushings: Control arm bushings are rubber components that reduce friction and absorb shocks. Worn bushings will be cracked, torn, or excessively soft. This will lead to a sloppy or wandering feeling while driving, and can impact alignment.
* Steering Problems: Difficulty steering, a wandering steering wheel, or pulling to one side could indicate worn or damaged control arms.
* Unusual Noises: Knocking, clunking, or squeaking sounds from the suspension, especially during turns or when driving over bumps, are strong indicators of control arm problems.
* Alignment Issues: If your vehicle consistently requires alignment adjustments, it may be due to damaged control arms. Repeated failures to achieve proper alignment despite repeated attempts strongly suggest underlying suspension damage.
It's crucial to understand: A slightly worn bushing might not require immediate replacement, but if multiple components show significant wear or if any damage is found, the entire control arm is usually replaced for safety and to ensure proper alignment. Ignoring these issues can lead to a loss of control, accidents, and expensive repairs. If you suspect a problem, it's always best to have a qualified mechanic inspect your vehicle.
