Many people feel a vibration like going on rumble strips while driving old Silverado to distant places.
Why does Silverado feel like going over Rumble Strips? Sometimes, your Silverado feels like going over rumble strips at normal speed, or idling is due to the unbalanced wheel, bent axle, and spark plug issue. In addition, poor alignment of tires, faulty struts, and broken motor mount also cause vibrations. Furthermore, the worn-out belts, engine problems, and inadequate fuel intake shake the vehicle even on smooth roads.
For example, if you drive your Silverado with these vibrations, it will severely damage the truck. Furthermore, you can face accidents when the vehicle is out of control.
The purpose of rumble strips is to make drivers attentive during fast or normal driving on the roads.
These strips cause vibration in the vehicle and transfer the audible tactic from the wheels to the truck body.
Damaged brake rotors
Brake rotors are an essential part of the braking system of the vehicle. When you press the brake pads, it squeezes the caliper, and rotors generate heat and friction.
Due to excessive heat, the rotors become weak and wrap. When you apply break in the presence of wrap rotors, you feel a vibration in the vehicle.
Moreover, with the accumulation of dirt, oil, and debris, you need more force to apply the brake using brake pedals.
As a result, the surface of the rotors rubs with the surrounding area and causes vibration in the pickup.
Poor alignment of tires
One of the significant reasons to feel a vibration in the truck is the tires’ poor alignment. You control the movement and position of tires using steering wheels.
Sometimes, the tires’ unbalanced alignment needs extra force to move the steering wheel.
Mostly you feel the shaking when you apply the brake or turn the vehicle right or left.
It also pulls the wheels towards each other, and you will feel the vibration. Therefore, it is better to check the alignment of tires as a diagnosis of a shaking truck.
Faulty struts
Struts are the springs under the Silverado that act as a shock absorber, but it is stronger than the absorber because it bears the truck’s weight.
Many people complain about the vibration in the pickup due to the presence of faulty struts. The worn-out struts produce knocking and clunking sounds.
You will feel like going over the rumble strips when it happens for a long time.
Moreover, the surface o the struts rub against the surface of the other metals and, in turn, creates issues.
It is better to replace the struts with the new ones.
Torque converter issues
The torque converter means transmitting the torque from the engine to the driven load. After that, it will rotate the wheels to move the pickup on the roads.
The improper working of the torque converter causes the jag in the vehicle, especially when you overdrive.
Moreover, the needle bearings of the torque converter wear out due to the extra load and low quality.
The broken solenoid of the torque converter also causes a shake in the vehicle when you start the engine. Changing the wear-out bearings and solenoid is better than repairing them.
Broken motor mount
The motor mount keeps the engine in its place and decreases its hitting chance to the nearby parts. When the rubber of the motor mount cracks, its grip weakens to hold the engine.
Sometimes use of rubber on the motor mount for a longer time loses its stretching ability.
As a result, the rubber will remain in the un-stretch condition and does not provide a grip on the engine.
You should check the motor mount whenever you feel like going over the rumble strips.
It is unsafe to drive with the damaged motor mount because it can damage the engine and lower its performance.
Driving over uneven terrain
Sometimes you have to pass through the rough and rocky paths to reach the destination.
Driving your truck on an uneven surface for about 2 to 3 hours shakes the vehicle.
You will feel jag over the journey due to the loose belts and improper positioning of the engine in the compartment. It happens due to excessive vibration over a longer time.
The professional recommends tightening the loose nuts and bolts before going on the tour. In addition, it is better to take your truck to the workshop when you feel the vibration.
Engine problems
When you start the Silverado, it generates heat in the engine due to the burning of the fuel.
The engine converts this heat into mechanical energy and produces torque to move the truck.
The blockage of air and fuel filters due to the accumulation of dirt and impurities will not mix it properly.
Moreover, the fuel will not go into the injector, so the engine will not get enough power and cause vibration in the vehicle.
Many people feel the shaking of the vehicle due to the low level of engine oil.
Therefore, you will feel shaking when the dry and jam engine parts work forcefully.
Bent axle
The axle is a metallic shaft present under the truck that moves the wheels according to the torque produced.
When you use the low-quality axle for Silverado, it bents after some time, and you feel the vibration.
Sometimes you put a lot of luggage on the pickup for camping and enjoyment. It stresses the axle and makes it difficult to move the wheels.
Driving with a bent vehicle feels like going over the rumble strips.
Therefore, it is better to change the axle shaft when it bents or is damaged by rust to avoid further damage to the vibration.
Worm out belts
Sometimes the worn-out timing and serpentine belts affect the other parts of the engine not to work correctly, and the vehicle will start vibrating with a knocking sound.
My friend was delivering the things on his Silverado, and suddenly he heard a strange noise coming from the truck. He ignored this sign and continued his journey; he felt the vibration while driving after some time.
He took his pickup to the mechanic and found the loose timing belt. In this way, old and damaged timing belts cause vehicle shaking when you drive on the smooth road.
Spark plug issues
The spark plug fires the fuel cylinder to generate heat for the movement of the truck and all the electronics appliances in it.
Sometimes the spark plug misfires the cylinders while driving or idling and creates vibration in the engine compartment.
The misfiring of the spark plug is due to the accumulation of dust and corrosion on it. It results in the shaking of the pickup and sometimes damages the engine badly.
It is better to replace the spark plug if you feel the issue after cleaning the clogged and rust from its surface.
Then, you can apply the lubricants or anti-rust spray to avoid misfiring and check its wire connections.
Poor fuel intake
Poor fuel intake is due to the misfiring of the spark plug that will ultimately vibrate the truck. the injectors spray the fuel to the cylinders for proper mixing with the air.
When the nozzle of the injectors becomes dirty and worn out, there will be no improper flow of fuel in the truck. It results in the vibration of the Silverado when you apply brake or int is in the acceleration.
You should clean the injectors when your truck consumes more fuel due to a poor fuel system.
It will reduce the chances of shaking and damaging the pickup when idling or moving.
Sudden speed change
Many people like to drive at a fast speed, and on the other hand, many people always drive at an average speed.
When you are driving your pickup at a higher speed, you abruptly apply the brake to stop when you see the other vehicle.
When you again try to access the fats speed, the vehicle will start shaking.
These abrupt changes in the speed affect the other parts that will ultimately feel like going over the strips on roads.
Unbalanced wheels
Sometimes the mechanic mistakenly adjusts the wheels in an unbalanced position. This unbalancing affects the suspension and axle of the truck.
Many people complain about the vibrating effect in the pickup when they drive with unbalanced wheel alignment.
In addition, it also unbalances the vehicle on the road while driving or idling at higher or normal speed. You can solve this issue by adjusting the wheel alignment with the axle.
