The suspension system in your vehicle takes care to ensure that your vehicle stays comfortable on the journey and remains safe by ensuring your tyres constantly make contact with the road. A suspension system that is properly maintained enhances the handling, stability and comfort of the car, whereas a neglected one would cause unnecessary bumpy ride, poor handling and steering. It is necessary to check and maintain your suspension system to ensure a smooth ride and promote your safety. In this post, we will outline some guidelines on how to check and maintain the suspension system of your car.

 

Understanding the Suspension System

 

 The suspension system contains several components that works together with an aim of avert sudden movements on the bumps/rough roads which may cause shocks, drop tires from the roads and lose the balance. The major parts included are.

 

 Shock Absorbers (Shocks) – helps absorb the force of a bump before taking over and preventing the vehicle from bouncing laterally.

 

 Springs: Springs, containing coils or leaves, support the weight of the vehicle and absorb road shocks.

 

 Control arms: these connect the frame of the vehicle to the wheels, enabling them to move up and down and turn but keeping them parallel to the vehicle’s frame.

 

 Ball Joints A ball joint connects the control arm and the steering knuckle, being a major pivot joint with a large distance to move and rotate. 

 

 Bushings: A type of a rubber or polyurethane piece that keeps metal parts of the suspension from chafing against each other as the car turns. It can also help absorb excessive movement.

 

Signs of a Worn or Failing Suspension System

 

 Before we get into maintenance and service, let’s discuss some of the key symptoms of a suspension system that is entering the danger zone. Worn or failing suspension components exhibit some of the following symptoms: 

 

 Bumpy Ride: If your vehicle is riding rough, or if it bounces excessively over bumps, you likely need new shocks or struts.

 

 Nose Diving or Squatting: When you brake, the front end of your vehicle may be seen as diving (nose diving), or the rear may be dropping down when you accelerate (squatting). Worn shocks or struts are under blame for this. 

 

 If any of these things sound familiar, it might be time for some new parts: Uneven Tire Wear. If the outside of your tyres is worn more than the middle or insides, there is a good chance that something is out of alignment. This is usually because suspension components have become worn.

 

 Pulled to the Left: Was your car pulling to one side? If a vehicle pulls to one side, even with the steering wheel straight, that would be an indication of a suspension issue, like worn balls or worn control arms. 

 

 Too Much Body Roll: If your vehicle leans too much in turns, your anti-roll bars could be worn out or your dampers (shocks) might be failing.

 

 Clunky or Knocking Sounds: Weird noises, either during rough or bouncy rides over potholes or speed bumps, or when making sharp turns, point to failing and worn suspension parts. 

 

Guidelines for Checking Your Suspension System

 

 Checking your suspension can prevent small problems from growing bigger and keep your car riding smooth, according to learnhowtoride.org. Here’s what that check should entail. 1. Look for abnormal shocks. This goes for any part of the car — odd noises can indicate a minor problem that will worsen over time. Any issue with the suspension system will make the car unsafe to drive. 2. Shake your tires. They should feel firm when shaken near the wheel. This check won’t reveal more dramatic results than a simple bounciness, but it would prevent you from buying a car with a serious problem in this area.

 

Visual Inspection

 

Start with a visual inspection of the suspension components. Look for the following:

 

 Shocks and Struts: Check for leaks around the shocks and struts. If the shocks or struts are leaking, it is time to replace them.

 

 Springs: inspect for cracks, signs of rust or damaged spring coils that could cause problems with the vehicle’s ride height and performance.

 

 Bushings: Check for wear, cracking or deterioration of the bushings. Excessive play in the suspension can develop if the bushings are worn.

 

 Control Arms and Ball Joints: Look for cracks, bends, rust and excessive wear or movement in the ball joints.

 

 Tip: Check this area every six months or 6,000 miles, whichever comes sooner, or any time you are experiencing one or more of the symptoms described above. 

 

Bounce Test

 

 Here’s the bounce test for shocks and struts.

 

Step 1: Push down firmly on the front or rear corner of your vehicle.

 

Step 2: Release it and observe how the vehicle responds.

 

Normal: The vehicle should bounce once or twice before settling.

 

 Worn Shocks/Struts: Your vehicle continues to bounce two or three times.

 

 Hint: The bounce test is something you should always do when you change your oil or rotate your tyres. 

 

Check for Uneven Tire Wear

 

 Tire wear is uneven when the tread is worn out more on one edge of the tire than the other. It can indicate that the suspension is out of alignment, worn-out shocks, or damaged control arms. Signs of uneven wear include surface noise or wobbling when the car is moving, an uneven appearance of the tire tread, or the sidew for uneven wear in tyres:

 

Step 1: Examine each tire for patterns of wear.

 

Signs of Issues:

 

 Feathering: Tread ribs are worn more on one side than the other, often due to misalignment. 

 

 Cupping: A scalloped or wavy pattern around the edge of the tread can result from worn shocks.

 

 Tip: Get in the habit of inspecting your tires regularly when they are rotated, and have your wheel alignment checked if you detect abnormal wear at the edges. 

 

Listen for Noises While Driving

 

 Be mindful of any abnormal noises coming from the suspension while on the road, especially over bumps or cornering.

 

Clunking/Knocking: May indicate worn shocks, struts, or ball joints.

 

Squeaking: Often caused by worn bushings.

 

 Quirky sound: Get any strange sounds checked out by a pro as quickly as possible before things get worse.

 

Guidelines for Maintaining Your Suspension System

 

 A suspension system that has not been maintained properly will begin to malfunction.And here is how to maintain your suspension systen so that you have a pleasant ride and stay safe:

 

Replace Worn Shocks and Struts

 

 Shocks and struts gradually wear down and will need to be replaced over time in order to maintain ride quality and handling.

 

 When to Replace: Once your shocks or struts start to deteriorate (usually between 50,000 and 100,000 miles, you’ll feel it in your vehicle’s ride quality. However, if your shocks and struts are getting old, wear and tear will start to become apparent, so it would be best to replace them on the early end.

 

 Note: Replace these in pairs to keep handling even and ride balanced. 

 

Regularly Inspect and Replace Worn Bushings

 

Bushings are used to absorb energy within the suspension and reduce friction. In the long run, they can become worn or break down.

 

 When to Replace: Inspect bushings during maintenance and replace them if they look worn, cracked or distorted.

 

 Tip: For an extra measure of durability and performance over the stock bushings, you might want to upgrade to polyurethane. Especially in cars that see track time. 

 

Keep an Eye on Control Arms and Ball Joints

 

 Control arms and ball joints keep the wheels aligned and help the suspension move up and down.

 

 When to Replace: Replace a control arm or ball joint if it is obvious that it is worn, cracked, or you have determined excessive play with your inspection. 

 

 Hint: If you replace a control arm or ball joint, have the vehicle wheel alignment checked and adjusted at the same time. 

 

Maintain Proper Tyre Pressure and Alignment

 

Proper tyre pressure and alignment are vital for maintaining suspension health and ride quality.

 

Tire Pressure: Check your tire pressure monthly and ensure it matches the manufacturer’s specifications.

 

 Wheel Alignment: Checked at least once a year or whenever you replace tyres, suspensions or if they’re uneven?

 

 Tidbit: Ensuring your tyres are in proper alignment will help them last longer and reduce stress on the wheel bearings and suspension, creating a smoother ride and improving your safety. 

 

Avoid Overloading Your Vehicle

 

 Carry too much weight and you could be rushing your suspension system into early retirement by wearing out springs, shocks and other parts.

 

 Don’t load your vehicle beyond its maximum load specifications in your vehicle’s owner’s manual. 

 

 If you frequently haul heavy loads, consider upgrading that suspension to heavy-duty components, such as beefed-up springs or high-end shocks.
