Identify where the shaking is coming from.
The first thing we have to decide is what happens when we shake it. Does it vibrate when braking? Does it vibrate when you accelerate and not when you let go? At what speed does it happen? Does it shake when you try to throttle? The answers to these questions will help you decide where to look for the cause of the vibration.
Does it vibrate when braking of car shakes at high speed?
Shaking at high speeds when braking is an indication of a brake problem. This usually means that the brake discs are not round and you can feel this when braking. The vibration only occurs when braking. If you feel it in the steering wheel, it is the front brake discs that are the problem. If you feel it in the seat, it is the rear brakes that are the problem.
Does it vibrate when you try to accelerate and feel like you’re losing power?
If the car shakes when you try to accelerate, it is usually an engine problem. A typical shock that occurs at this time is usually engine failure. This misfire can be caused by a bad ignition coil, a bad spark plug, a problem with the fuel system, or a mechanical problem with the engine. Continuing to drive in this case may cause further damage to the vehicle. Investigating this issue should be a top priority.
Does it shake when accelerating and hasn’t it lost power to car shakes at high speed?
These vibrations can have a variety of causes, but the biggest culprit is usually a powertrain problem. These problems are caused by worn CV shafts and drive shafts with bad U-joints. The shakes usually occur when accelerating to highway speeds and then stopping. The shake can come and go and seems to have little consistency. It is very important to inspect the drive shaft universal joints and joints at constant speed because if they break they usually cause a lot of damage as they rotate at very high speeds.
Another thing that can feel the same as a bad u-joint or constant velocity joint is a worn suspension. Loose tie rods, ball joints, bushings, or other worn suspension can cause vibration because play allows the steering wheel to move back and forth without any input from the steering wheel. This should be addressed immediately as failure to use may result in an accident and total failure.
At what speed does the shaking start to car shakes at high speed?
If your car starts shaking at about 30 mph, drives fine, and continues to shake up to freeway speeds, there is likely a tire balance problem. This problem is always confused with an adaptation problem. Alignments very rarely cause vibration problems. However, tire balance problems are common as the tire can become unbalanced as it wears. Tires can also be a problem if they have problems with the inner structure of the tire. In this case, balancing the tire may not work and the tire may need to be replaced.
Does the vehicle start vibrating at a speed of 60 km/h on a flat surface and not when driving uphill?
This is a fairly new issue that we are dealing with. It almost sounds like you’re running over rumble strips when that happens. The cause is usually a defective motor mount. Many new cars have a fuel-saving function that turns off part of the engine when driving steadily. When the engine shuts down the engine cylinders, an electric engine mount is used to remove excessive vibration from the engine. When the engine mounts break, a rumbling sound is heard throughout the car.
These are some of the main factors that can cause vibration at highway speeds. The easiest way to help your technician quickly find the cause of the vibration is to provide a good description of when the vibration occurs. This allows them to reproduce the problem so they can fix it faster and save money.
Shaking at high speed is often due to imbalance between wheels and tires
One of the most common causes of vehicle vibration on the highway is the wheels and tires. If your wheels are not properly balanced, you may feel vibrations at higher speeds. Although the shaking may only occur at certain speeds, for example between 80 and 100 km/h, it is still important to pay attention to this warning sign.
A bent wheel can also cause vibration at high speeds. If you feel vibrations on the highway, you should visit a tire shop for an alignment and see if you need a new wheel.
Tires with uneven wear or poor tread also cause vibrations, as does rubber that has lost its shape after a few months of inactivity. In these cases, it is generally best to replace the worn tires.
Ball joints and tie rod ends can also be the cause to car shakes at high speed
Also check suspension bushings, nuts and bolts. Everything must be substantial and free from wear.The most common way to identify a broken wheel bearing is to hear a grinding noise, but it can also rattle the car at slower speeds and buzz when you drive faster.
A shoulder problem could also be to blame
A bent axle caused by hitting a bad pot hole or similar is another possible cause of your car’s vibrations, especially if these vibrations get worse the faster you drive. If a constant velocity joint or constant velocity joint wears, or if a constant velocity joint becomes cracked or damaged and dirt enters the joints, vibration can occur.
Finally, a bent driveshaft can also make you feel like you’re driving through mud. The drive shaft transfers power from the transmission to the front or rear wheels.You will be able to feel if it is bent.In all these cases, the only solution is to replace the worn or bent part.
A shaking car is a serious problem that you should not ignore. The solution can be as simple as a simple alignment or as complicated as replacing the drive shaft. In any case, it is usually safest to fix the problem as quickly as possible. Read more
