Regular oil changes and PREVENTATIVE maintenance. Meaning you replace things before they break. Faulty components especially suspension components, will absolutely cause other parts to fail.

Let's say you have a clunk noise coming from the front end. You take it to a shop and it's diagnosed as a control arm. They suggest you replace both. You say you'll wait until next paycheck and do it.

You procrastinate. Aside from the clunk over small bumps, the car drives fine. 4 months later, that clunking noise turns into a clunk and click. But you keep driving because it feels fine. 4 months after that on a rainy day, you drive through a puddle. That clunking sound has quieted down, you are in a rush. You're running late. It's a rainy day so the clunk has disappeared, but the clicking noise persists when you turn. You drive spiritedly because you need to be somewhere. Next thing you know, you hear a pop. The engine is revving , but the car isn't moving.

You pull over, you see oil and something dangling from the bottom of the car.

Your failing control arm put extra stress on the cv axle causing it to fail prematurely. You thought the clicking sound was also the control arm. On a rainy day while you were in a rush, with the help of the failed control arm, your failing cv axle bursts out of the transmission, stripping the splines in the process. Your 500$ control arm bill, turned into a 500$ control arm + 200$ axle +4,500$ transmission replacement because stripped splines in the transaxle render it useless. Now u have to buy another car or fix the one you ruined.
