Suspension Maintenance: Helping the Rubber Meet the Road

There’s a lot of talk about your car’s tires, and rightfully so. But that rubber is guided towards the road by a complicated assortment of joints, bolts, and metal pieces. It’s what keeps your car comfortable on the highway and on twisty mountain roads: your suspension.

As one of the most hidden parts of your car, suspension maintenance is easy to ignore. It’s also one of the hardest worked. Suspension maintenance isn’t as frequent as other parts, but it still pays to stay on top of it! Here are some parts of your suspension you should know about.

Axles and CV Joints

Own a front wheel drive car? Unless you have a truck or a sports car, you likely do. All front-wheel drive cars use a CV joint (sometimes called a CV axle) to transfer power from the transmission to the wheels. The unique layout of front-wheel drive cars requires a specialized axle with a very flexible joint system, covered by a rubber boot. Over time this rubber boot can crack, removing the joint’s lubrication. Not a good thing to happen while you’re driving!

Control Arms

Your wheel is connected to your car’s frame by a forked metal part called a control arm. As your wheel bounces across the road, the control arm rapidly moves up and down to compensate for the motion. Most control arms are long-lasting, and aside from excessive salt will last a long time. The weaknesses are the rubber and metal bushings that facilitate that motion; have your mechanic check them for wear and tear.

Shocks

Shock absorbers live up to their name: they smooth the motion between your wheels and the body of your car, making bounces more graceful. But when they break, it’s more than an issue of comfort! Bad shocks cause premature tire wear, which gets expensive fast. They can also cause your car to sag, damaging your undercarriage during bumps.

Ball Joints

Your steering system’s final step is at your ball joints, small metal joints that allow steering knuckles to turn your wheels. When they break, you can lose control of your car! Signs of wear include a cracking or groaning sound when you turn the wheel. If you start hearing those noises, you need to have your ball joints checked as soon as possible.

Good info. I had ball joint failure one time at 40 mph in a turn. Wow!
