Not replacing the control arm poses potential dangers, which can lead to abnormal noises in the chassis or even looseness in the chassis. Below are the precautions for replacing the control arm: Using a Jack: First, lift the car with a jack and place bricks around the car for added safety to prevent the jack from failing. Pay Attention to Direction: Remove both ends of the control arm, select two corresponding-sized metal sleeves, and install the rubber bushings. Larger rubber bushings need to be distinguished between left and right, marked with L for left and R for right, while smaller ones do not require differentiation. Apply Dish Soap: After removal, use a torch to burn out the middle metal sleeve. Apply dish soap to the new one for easier installation, as it acts as a lubricant and does not corrode the rubber. Do not use engine oil.

It's absolutely dangerous not to replace a broken control arm. As an experienced driver, I must make this clear. The control arm is the core component of the suspension system, responsible for fixing the wheel position. If left unrepaired when cracked or deformed, first the handling performance will significantly deteriorate – the car body will sway severely during turns, potentially leading to loss of control or rollover at high speeds. Secondly, it causes uneven tire wear, dramatically increasing tire replacement frequency. In severe cases, the wheel might even detach, causing accidents. I've seen a friend scrape against guardrails because of this, costing tens of thousands in repairs. My advice: get it inspected immediately when you hear abnormal noises or notice steering deviation. Don't gamble with safety to save money. Healthy suspension is fundamental to safe driving – have mechanics check it during regular maintenance. Simple prevention can avoid major disasters.

Having worked in the auto repair shop for so many years, I've encountered numerous vehicles with problematic control arms. If not replaced promptly, the initial symptoms include squeaking noises when going over speed bumps, followed by heavy steering and difficulty in handling. The danger lies in rainy or icy road conditions, where the wheels' grip weakens, making them prone to skidding or even rolling over. I've seen cases where owners tried to save trouble, only to have a wheel come off at high speed, causing an accident. The safety risks go far beyond that; damaged control arms can also shorten the lifespan of shock absorbers, leading to more malfunctions. My advice is not to delay once the problem is diagnosed—find a professional shop to handle it quickly. Always pay attention to any abnormalities while driving; the health of your suspension is a critical line of defense for road safety.

Last year, my car's control arm failed, but I ignored it, which turned out to be extremely dangerous. During turns, the tires shook noticeably, and after braking, the wheels were unstable, nearly causing a rear-end collision. The direct danger of not replacing the control arm is loose suspension and a high risk of losing control, especially on complex roads like mountain paths or curves. Worse, prolonged driving can deform the tires, potentially leading to blowouts and accidents. Now, I've made it a habit to regularly check suspension components. Remember, don't overlook small issues—safety comes first. Early repairs can save both peace of mind and money.
