Why is Your Truck Bumpy

Introduction of Truck Bumpy

  • When you drive a truck, you certainly want to drive smoothly. However, when the truck bumps on a smooth road, you may need to consider the truck. If the truck makes excessive rumbling, vibration, collision or shaking, please note that this is a potential fault sign of the truck. But where exactly did the failure occur? What do you need to do to fix it? Don’t worry. First, you need to make a correct judgment. In fact, there may be several reasons for truck bumps. We will list some of the most common culprits here, but to get a clear diagnosis, you may need to have a professional check your truck.


Tire Problems

  • First, you need to check the truck’s tires for problems. This is the most likely culprit, but it is also the easiest to fix. On the one hand, truck bumps may be caused by insufficient tire air and incorrect wheel alignment. On the other hand, there may be rocks or debris stuck in the tire. Secondly, the imbalance of tires also causes the truck to feel bumpy when driving on a smooth road. Because the quality of the steel rims and rubber tires cannot be uniform, the tires will shake severely when rotating at a high speed, resulting in a bumpy feeling. The last reason may be low or high tire pressure. If the tire pressure is too high, the tire may deform, then it will quickly wear and burst on the tread, and the truck will feel bumpy when driving; If the tire pressure is low, your truck will also feel bumpy. These problems can be solved easily and quickly, so I hope one of them can explain the problem of your truck bumping.

Suspension Problems

  • We know that, in reality, even a smoothed road will have a little pothole, so it is necessary to rely on our truck’s suspension system to absorb or reduce the bumpy feeling when walking through the potholes. The suspension system mainly relies on the spring to absorb bumps. The role of the hydraulic shock absorber is to reduce the repeated stretching times when the spring absorbs vibration so that the vehicle’s stability can be greatly improved. Therefore, if your truck is bumpy, it may be that your truck’s suspension system has a problem, which causes the truck to feel bumpy on a flat road. Failure of the suspension system may cause premature wear of your front-end components, resulting in uneven tire wear and an unsafe driving experience. So how do you know if your truck suspension system is malfunctioning? One obvious sign of suspension failure is that the truck may lean to one side, allowing you to feel your truck dragging on the ground. When you drive on a dangerous road, it will bounce up and down like a very loose spring, settling down.


Transmission problems

  • There is a problem with the transmission. This may also be the reason why your truck bumps. If you notice bumps when shifting gears, it is very likely that the transmission of your truck has problems. The longer the transmission problem lasts, the more complex and expensive it is to fix it. Therefore, you need to find and solve this problem as soon as possible. There are several reasons for the failure of the transmission system. The first is the failure of electronic and electrical components of the transmission; The second is the mechanical failure of the transmission model, such as idling of the engine, slipping of the transmission, burning of the clutch, and the failure of the refueling truck; The third is that the oil temperature of the transmission is too high, the radiator of the transmission is blocked, etc. However, in general, the failure of the truck transmission will cause the transmission fault light to light up. At this time, the truck owner needs to check whether the transmission oil leaks and whether the transmission is overheated.

Brake problems

  • Brakes are also an important part of trucks. If you think your brake is more sensitive or slower than normal, or your truck screams or groans when it bumps, it may be that your truck’s brake has a problem. If we use the brake excessively when driving on steep slopes, we can strongly smell the smell of the brake and feel that the brake is slow and overly sensitive. A very important factor affecting the brakes is the weather. If you drive in an area with bad weather and continuous rain or hail, this may cause the brake to sound or malfunction. So how do we know if our brakes are malfunctioning? In fact, it is very simple. We only need to step on the brake a few times to check the reaction of the brake. Many times, if you step on the brake regularly, it will have the effect of removing dirt or moisture. However, if you check your truck brake in this way when the weather is good, but the brake still does not respond, then this is bad news for you. Your brake has encountered a problem.



  • Above, we have summarized several reasons that may cause your truck to bump. To put it simply, in most cases, the reason for truck bumps is that the tire or tire position is incorrect, which requires you to ensure that the nuts and bolts on each tire are correctly fixed when replacing tires. Secondly, if your tires are normal, but the truck still has a bumpy problem, you should check the transmission and brake system immediately.
  • Please keep in mind that there must be a reason for the bumping of the truck. Usually, we need to replace or repair some truck parts. Before the problem becomes more serious, you need to find it in time and send your truck to repair immediately! Please do not ignore these small signs of failure and procrastinate. It’s better to be safe than sorry.
