Why Car Feels Bouncy When Driving?

Car Is Bouncing

Short answer: The main reason why a car bounces while driving mainly comes from the tires, the wheel system, or the brakes.

Since the operation is based on their close relationship, a problem with only one part will cause the system not to function as it should.

Determining the specific source of the incident facilitates the assessment of the severity and the direction of resolution. Here are some of the most common causes of your vehicle’s jolts.

Bad Tires

When you’ve just had a bumpy ride, you should first check your tires. Preliminarily determine with the naked eye whether they are deformed or flat.

Also, remember when you last inflated and checked the tire pressure.

Check tire wear by applying an even layer of water to the entire tire and driving forward about 5 meters. After observing any tire tracks left behind, you will know if the tires have uneven wear.

Tire pressure often changes negatively due to tire type, weather conditions, external forces, and temperature. If your car has a tire pressure gauge available, it will greatly help in this situation!

If the measured pressure readings are lower than the specified specifications for your vehicle, you can go to the nearest gas station/car repair shop to refill.

If the problem persists, you may need to replace the bad tires on your vehicle.

Transmission Problems

You may not pay much attention to it, but a faulty transmission can cause the vehicle to jerk abnormally, even on a flat road.

Verifying this suspicion yourself is difficult, so it is best to ask a mechanical expert. Unfortunately, transmission problems often cost drivers a lot of labor costs and brand-new replacements.

Bad Brakes

The driver can detect brake problems if the car makes strange noises every time the brakes are applied. If you are unlucky enough to be stuck in this case, ignoring it puts you at risk of a traffic accident.

Therefore, it is best to park your car on the roadside and contact the car rescue team to assist in transporting your vehicle to the nearest car repair station.

Suspension Problems

The car’s suspension system supports operating smoothly and is always under the driver’s control. If this system has trouble, it will send a distress signal to the driver through the following signs:

  • The car jerked violently before coming to a complete stop.
  • A more exaggerated reaction than usual when encountering a bumpy road or pothole.
  • Vehicles tend to lean more to one side.

If you are unsure of the signs above, you can check for yourself by pushing the bonnet with all your might and immediately releasing your hand.

If the car is bouncy more than three times, you can now conclude the main source of the problem is the bad suspension.

Drivers are advised not to drive after determining the suspension has failed. Instead, they should take the vehicle to a repair shop to have it checked and replaced with wear-resistant replacements.

Bad Shock Absorbers

The shock absorbers help limit the forces acting on the wheels, allowing the tires to maintain stable traction.

But as long as the springs have a problem, they absorb too much of the bouncing force, causing vibrations and wheel slip.

Poor Wheel Alignment 

Proper wheel alignment helps the wheels move straight and evenly, which limits uneven wear on the tire surface.

Some physical impact or incorrect installation can lead to loss of control and misalignment of the springs, causing vibrations throughout the journey.

Broken Struts

The strut connects the lower ball joint and the upper strut bearing, ensuring the vehicle is always in contact with the road surface.

Failure of this critical component can damage surrounding components, causing the car to lose control. That’s why my car is bouncing when I drive!

Faulty Steering Wheel System

Faulty steering wheel systems can result from worn steering belts or leaking and clogged ducts. It has a very easy tell-tale sign – the steering system is defective.

For example, you turn the steering wheel, but only when you turn the steering wheel more than 1 inch will the wheel respond.

Damaged Ball Joints

The ball joint controls the steering knuckle’s actions to link with the control arms, creating a smooth movement for the suspension system.

Once this part fails, the most obvious sign is that the car is bouncing up and down with rattling noises from the engine compartment.

Broken Driveshaft

You can’t prevent natural wear and tear over time from damaging any part of your vehicle, including the driveshaft.

Especially when experiencing an unexpected external force (such as an accident), the incoherent operation of the components inside the damaged drive shaft system will make the car bouncy when decelerating and moving at a slow speed.

Repair The Car Bouncing

Once the source of the problem has been identified, it’s time to roll up your sleeves and begin the repair work

If you’d rather do the job yourself instead of seeking the help of professional mechanics, then don’t miss any of the details in our guides below!

Control Arms And Replace The Bushings 

Due to the alignment of the suspension and front wheels, replacing components in this system can strengthen the suspension and improve driving performance.

But before embarking on the repair work, preparing a pair of gloves and a pair of glasses will save you a lot of trouble.

Tools Required

When choosing a new controller, evaluate its compatibility with your vehicle. Then make sure you have all the required tools below:

  • Carjack
  • Threadlocker
  • Jack stands
  • Wrench set
  • Ratchet wrench
  • Screwdriver
  • Metal wire brush
  • Rubber hammer / mallet
  • Automotive grease
  • Torque wrench
  • Trailer arm assembly

Step-By-Step Guide

First, you need a jack truck to raise your vehicle to the proper height. Then, set up the supports so the car cannot move during the work.

Remove the pull rod and remove it from the lower frame, then loosen the bolts holding the joystick.

After removing the joystick, install the new trailer so that its position aligns with the vehicle body support. Using a Rubber hammer/mallet would be great if you need to immobilize the assembly.

Then, use the supplied bolts and nuts to secure the trailer arm to its original position and adjust the jack so that the vehicle’s weight rests on the bushing.

You must tighten the bolts to about 50 pounds, then carefully grease the bushings.

It’s time to remove the faulty control arms, apply automotive grease to the bushing and mount it to the bracket. You should lightly tap it with a hammer to flatter it, then grease the handlebar socket.

When assembling the handles, place them with the correct initial orientation. Adjust the jack until the weight is on the axle, then tighten the bolts around the joystick with a force rating of about 70 pounds.

Rebalance Tires

Fortunately, unbalanced wheels do not require many specialized tools and expertise so any driver can do it at home. Follow our guide to rebalancing tires below to complete this challenge!

Tools Required

Gather the following tools to begin the repair process:

  • Screwdriver
  • Heavy-duty glue
  • Lug wrench
  • Plywood
  • Small weights
  • Portable wheel balancer

Step-by-step Guide

First, you must use a lug wrench to remove the complex wheel assembly from the tire and set it neatly aside. Place the portable wheel balancer on top of the plywood, then add the balancer on top of the base.

You need to adjust the bubble on the balancer by adding weight to the wheel assembly. Once you have achieved the desired result, use glue to secure the weights to the wheel.

Finally, reassemble the wheel assembly and test drive it to check if the balancing is successful.
