A bouncing SUV is not comfortable for people who want a smooth ride. Many people think that all SUVs are bouncy; it is not true this issue comes due to their faulty systems.
Why is My SUV So Bouncy? In general, your SUV can be so bouncy due to bumpy roads, poor wheel alignment, and loosen steering system. This issue also occurs in SUVs due to damaged coil suspension springs, faults in shocks and struts. In addition, transmission issues, damaged ball joints, and malfunctioning in mounts and arm bushings can make your ride bumpy.
It also compromises safety; that’s why you need to fix this issue as early as possible.

Why is My SUV So Bouncy?
I have added 18 different reasons that make my SUV so bouncy and their solution to fix this issue.
Rims are present in your wheels, and they give them an attractive look. In addition, tires and wheels provide significant support to your vehicle.
The heavyweight on wheels causes the bending of rims. They are made of aluminum and steel, and their strength is decreasing when they become old.
The dive on the bumpy road also cause this issue. When the rims are bent, it increases the friction between the tires and road surface.
This issue eventually affects the control of steering. It can also damage the tire, and you can not handle it properly.
It would help if you repaired the bent rims to protect them from more damage. If they get old, then buy new rims of high quality that last for a long time.
Avoid high speed on bumpy or unsmooth roads.
Wear and tear in wheels
The uneven wear occurs in your SUV because of high inflated pressure in them. However, it may also occur due to low air pressure in them.
The tires can also be wear due to road hazards while driving. The loose or damaged internal bearings can also cause damage to them.
If you feel any wear in them, take the technician’s help and repair them or replace them with new ones.
The bearing lasts for a long time but check them sometimes; it can be damaged.
Poor alignment of SUV tires
Poor alignment and unbalancing of tires are occurring due to damage in them. As a result, the tread of the tires becomes smooth, which decreases the friction between them and the road.
The hitting with potholes and curbs causes the unbalancing of the wheels. It can also be caused by unequal or unbalanced weight in your vehicle.
Check the alignments of wheels and fix this issue by their poor alignment. If the tread is damaged, then replace them with the new one.
The unbalancing of the wheel also needs to be fixed with the help of a professional technician. Check the alignment of your SUV if the steering wheel is moving to one side.
More air pressure in tires
The average tire pressure in SUVs ranges from 32 to 38 for standard conditions. The more air pressure than standard one causes unbalancing of wheels.
When the tires are overinflated, and you are driving at high speed, it causes bouncing in your vehicle.
Due to overinflated tires, you can also feel that steering is loose.
Check the pressure of tires with the pressure gauge and compare them with the standard.
Do not overinflate your tires; it can cause damage to them. Instead, it would help if you inflated the tires with recommended standard air pressure.
Unequal road surface
The bumpy or unequal road surface makes it shake because it can damage the shock absorber and spring.
It feels like that your vehicle is leaning towards one side. The poor alignment in wheels occurs due to driving on the unequal road surface. It can also cause damage to the tread surface of tires.
Do not drive fast on these types of roads to fix the issue. If the bearings and shock absorber get damage, then change them.
Faulty shocks and struts
The shock absorber and struts are the central part of your SUV; they stabilize the movement.
The high-quality shock absorbers make your vehicle smooth on bumpy roads. Struts are also connected with springs and control the movement.
Due to damage in shocks and struts, your vehicle cannot hold the tires properly on the road. As a result, it will cause up and down movement in them.
The damaged shock absorber also produces a squeaking sound at low speed. Due to damaged shock absorbers and struts, the steering wheel shakes more, even on smooth roads.
Replace them after every 60.000 to 90,000 miles or better results. Replace the shock absorber in pairs and also replace struts with them to fix this issue.
Damaged suspension springs make SUV bouncy
These are also called the suspension springs and coiled springs; they keep the SUV tires at their place.
The suspension system in the vehicle also reduces the friction between the road and tires. It can also act as a protective barrier of shock absorbers.
They are present in pairs of two to support the vehicle, and their primary function is to keep the contact of wheels with the surface of the road.
The damaged spring coils cause up and down and bounciness in your vehicles. It also causes sagging in one side; this side becomes lower than the other due to instability.
The damaged springs also produce a clinking sound in the suspension coil.
Change the coil springs when they become old and worn out to fix these issues. Replace the broken coil springs with new ones for smooth and comfortable driving.
Damaged brake system
The damaged brake system itself does not cause this issue; it is the rotors that make trouble.
The rotors may be bent or compressed due to overheating issues. The overheating occurs in them when you apply brakes excessively at high speed.
The overheating also damaged the metal layer on it and caused warping and malfunctioning of rotors.
When you apply brakes, the brake pads are compressed against the warped rotor surface it can make your SUV bouncy.
In this situation, change the wrapped rotors and avoid the high speed. It will also be beneficial if you use high-quality cross-drilled and slotted rotors that provide better ventilation.
Faulty ball joints
The ball joints are present on the front wheel suspension system. Their movement allows the suspension system to work correctly.
The ball joints on the front wheels connect control arms and steering knuckles for their movement and smooth driving on roads.
The loose and damaged ball joints also cause shaking of the steering wheel.
The worn-out joints also produce clunking sound and cause drifting in steering. It can also disturb the stability and control of your vehicle.
Change the damaged or worn-out ball joints with the new one.
Problems in the SUV steering wheel
The steering system allows you to control the movement of your SUV. However, there is a difference in the working and efficiency steering of a new and old vehicle.
The steering and other parts connected to them can be worn out or damage when it becomes old.
The steering linkage becomes loose and decreases its stability and control.
Due to loose steering, the rack bushings also become loose when you move them.
Tighten the steering to fix this issue but do not make them too much tight. If the steering rack bushings are worn out or damaged, then change them.
The problem in the engine is caused by a faulty or loosen timing belt. Due to this, the other components attached to them and the fan do not rotate in a controlled manner.
This consistent working produces shaking in the engine compartment. Check all the belts to prevent shaking.
Replace them and add new parts.
Check the hoses and fix the loose and disconnected hoses at their place to prevent this issue.
Damaged SUV axles
The axle connects the wheels and allows them to rotate and bear the vehicle’s weight.
The axle of the wheels can damage due to accidents or other problems. Due to bent or damaged axles, the wheels of the SUV cannot rotate properly.
Fix the bent axle with the help of a professional technician. If they are damaged completely, ten change them to stable the wheels.
Transmission issues in SUV
A transmission system means that when you change gear, it supplies the power from the engine to the drive axle and adjusts the speed.
The defective transmission system produces bounciness when you change the gear of the vehicle.
This problem occurs due to the low level of fluids, or the fluids need to be changed. It also causes slippery gears and leaking of fluid in them.
The change of transmission system is a costly and time-consuming process, but you have to fix this to prevent it from shaking. If the fluid level is low, then refill the fluid and change it.
Loosen or damaged rack bushings
The rack bushings are attached with steering mounts, and they reduce the vibration and bounciness in SUV. These steel bushings are wrapped in rubber material.
Sometimes they become loose and produce a clunking sound in the vehicle.
The damage of rubber occurs due to heat road debris and water, and it can shrink, and cracks appear on it; this will also damage the steel part of bushing.
These bushings are attached to steering; therefore, when they become loose or worn out, they cause a problem when you move the steering.
They also cause bounciness in the steering wheel. Tighten it and secure it properly to fix the issue.
If they are completely worn out, then change them. The cost of this bushing mount depends on the quality; it ranges from 15$ TO 30$. It will take a maximum of 2 to 3 hours to change them.
Damaged body mounts
Body mounts are made of steel and have a rubber covering to make your SUV stable. In addition, they connect the vehicle frame to their body.
Check the condition of body mounts by using flash and change them if they are worn out.
The cost to change them is a maximum of 55$ TO 65$, and it takes a maximum of 3 to 4 hours for the whole procedure.
Faulty arm bushings
The SUV has two arm bushings to make them less bouncy. In addition, it connects the wheel hub to the frame of the vehicle.
Then loosen, or worn-out control arm bushings cause poor alignment of the vehicle. They also control and stabilize the upward and downward movement of tires.
They are connected with a suspension system the torn-out bushings cause shaking of the steering wheel.
Loosen motor mounts
Motor mounts are also called engine mounts; they keep your engine in place. They also separate the engine from the transmission system.
If you drive with broken mounts, it can also damage your vehicle.
Due to improper installation or aging, they break.
It causes makes vibration due to the continuous shaking of the engine.
Change the worn-out broken mounts carefully and adequately fix them in their position to solve this problem.
This whole procedure maximum takes 1 to 2 hours, and the cost required to change them is 50$ to 70$.
Spark plug issues
The issue in the spark plug occurs when it does not get proper air and fuel for its ignition due to a fault in the engine.
The spark plug blowout comes when you fasten them too tightly and install them slightly away from the engine.
Due to this issue, all cylinders do no ignite properly and cause bouncing in SUV when you start them.
Loosen the spark plug, so they provide proper ignition. If the spark plug knockout occurs, then change it.
