Buying an older used car can be a smart way to save money, but it comes with its own set of challenges. One of the most overlooked areas is the suspension system. Your car’s suspension isn’t just about a smooth ride—it’s key to safety, handling, and even tyre life. If you ignore it, small issues can quickly turn into costly repairs. Let’s break down some of the most common suspension problems in older vehicles and how to spot them.
1. Worn Shock Absorbers or Struts
Shock absorbers and struts are the heart of your suspension system. They control the car’s bounce, sway, and stability. Over time, these components wear out, leading to a bumpy, uncomfortable ride.
Signs of worn shocks include:
- The car bouncing excessively over bumps
- Nose-diving during braking
- Uneven tyre wear
In older cars, especially those with high mileage, replacing worn shocks can instantly improve ride comfort and vehicle handling.
2. Sagging or Broken Springs
Springs support your car’s weight and maintain ride height. In older vehicles, springs can sag or even crack, particularly if the car has been carrying heavy loads over the years.
A sagging spring may cause your car to lean to one side, affect steering, or create uneven tyre wear. If you notice your car sitting lower than usual or leaning when parked, it’s worth getting the suspension checked.
3. Worn Bushings
Bushings are the rubber or polyurethane cushions between suspension parts, helping to absorb shocks and reduce friction. Over time, these can crack, harden, or wear away.
Symptoms of worn bushings include:
- Clunking or knocking sounds over bumps
- Loose or imprecise steering
- Increased vibration inside the cabin
Replacing bushings may seem minor, but it dramatically improves comfort and stability.
4. Faulty Ball Joints
Ball joints connect the control arms to the steering knuckles, allowing the wheels to move up and down and turn smoothly. In older vehicles, ball joints can wear out, leading to uneven tyre wear and poor handling.
Watch out for:
- A rattling or knocking noise when going over bumps
- Steering that feels loose or wanders
- Tyres wearing unevenly across the tread
Ball joint failure is serious—if ignored, it can lead to a wheel separating from the vehicle while driving.
5. Leaking or Damaged Strut Mounts
Strut mounts attach the strut assembly to the car and help isolate road vibrations. In older cars, these can wear out or develop leaks, especially in areas with rough roads or frequent potholes.
Symptoms include:
- Loud clunking noises when turning or driving over bumps
- A rougher ride
- Steering misalignment
Replacing strut mounts restores smooth steering and ride quality, making driving safer and more comfortable.
Real-World Tip
I recently helped a friend inspect a 10-year-old Subaru they were considering buying. On a short test drive, the car felt bouncy, and there was a subtle clunking sound over speed bumps. A quick check revealed worn shocks and bushings—problems that would’ve been expensive if left unnoticed. Spotting suspension issues early can save thousands in repairs down the line.
Keeping Your Ride Safe
Suspension issues are common in older used vehicles, but many problems are easy to spot if you know what to look for. Regular checks, test drives, and professional inspections can prevent small issues from turning into costly repairs. After all, a well-maintained suspension keeps your car stable, your tyres wearing evenly, and your drives safer and more comfortable—whether you’re navigating city streets in Melbourne or hitting the open roads along Victoria’s coastline.
