Troubleshooting Problems With Steering and Suspension

Troubleshooting Problems With Steering and Suspension

By:  –Auto Repair Expert
Your car’s suspension system is an intricate network of cooperating (usually, anyway) components designed to give you a smooth, even, stable ride. Since the suspension is ground zero when it comes to road abuse, the parts wear out, and even break. If your car doesn’t seem to ride like it used to, you may have a problem down below.

It may seem daunting to try to diagnose steering or suspension problems, but if you attack it systematically, you have a fighting chance.

Just find the symptom that sounds like you and see what the probable causes are.

Money Saver: Before you start replacing parts, it’s a good idea to check all of the mounting nuts and bolts to be sure the problem isn’t being caused by simple looseness!

  • Worn or broken tie rods or steering rack – inspect steering components and replace as necessary.
  • Worn ball joints – inspect ball joints and replace if needed.

One thought on “Troubleshooting Problems With Steering and Suspension

  1. I have noticed that my car had a pretty solid clunk when I go over speed bumps. I guess I should probably get the suspension looked at. I wonder if I did something to it since it’s such a new car.
