8 Reasons an F150 Shakes & Shudders When Accelerating + Fixes

Vacuum hose Brake caliper The first step is to remain calm and go through a checklist to rule things out bit by bit. Why an F shudders when accelerating It may start as a simple issue that leads to a bigger problem if it is not fixed soon enough. The quicker you get to the source of the shaking and shuddering, the better. Wheels and alignment One of the first things you should do is check and see if the tires are firmly attached to the wheels.

Make sure they are balanced as well. A loose tire can cause shaking during acceleration and may lead to accidents if it is not fixed. If they are not properly torqued down on the wheel, some could have become loose over time. How to fix it: Check for loose lug nuts and tighten. If the shaking happens after new tires have been installed, then the unbalanced tires need to be fixed by a tire installer. They will mount the tire on a balancing machine to fix the error. They can also inspect the wheel.

Motor mount If your Ford F is shuddering when accelerating, the motor mounts can sometimes be to blame. When the motor mounts are damaged or broken, the vibration of the engine is no longer contained. The shaking will become noticeable, and may become worse when accelerating, because the engine must work harder. How to fix it: Assess wear and tear by checking the bolts that hold the mounts in place.

Sometimes there may be one damaged motor mount, other times it may be all the mounts. Then, check the rubber that holds the two metal mounting points together. If the bolts are loose, tighten them. If the rubber is cracked or spongy, it may be time to replace it. A truck engine is large and may require a jack and blocks of wood in order to check for broken motor mounts or other signs of wear and tear.

Another way to check is to watch for excessive movement around the motor mounts while a friend revs the engine. You might need to replace the motor mounts. Spark plugs If the motor mounts have no issues, then check your spark plugs next. The plugs are essential to keep your motor running smooth and prevent the engine from burning extra fuel.

They are small metal pieces that are inserted into the engine to provide the spark needed to ignite the fuel. When spark plugs become worn or damaged it can lead to a misfire. It could also cause an increased vibration in the vehicle, particularly when your F accelerates. Spark plugs should be to be inspected and changed periodically. How to fix it: Check spark plugs immediately. Take them out and check for deposits.

If it looks black or dirty, it may need to be cleaned or replaced. Look at the plug wires and make sure they are not damaged either. As you inspect the spark plugs watch for an excessive spark plug gap, because it may cause the ignition coil to misfire and fail. Install new spark plugs is a better idea. Some people prefer to try and clean the spark plugs to see if they still work, but it is advisable to replace them by purchasing new spark plugs.

While it may be cheaper to replace the spark plugs yourself, it usually requires experience and skill to do it right. Keep in mind, it may take several hours to complete. Fuel injectors Fuel injectors play an important role, they deliver necessary mixture of fuel and air to the engine.

Over time they may become dirty. When the injectors are faulty or damaged it can affect the torque and cause your F to shake and shudder while accelerating. There are a few ways to determine if the fuel injectors are at fault for the shaking when accelerating.

You can listen for certain clunking sounds and watch for any shaking when you press down on the gas pedal. Or, they can be tested with machines. The engine has an internal diagnostic on board that can send a series of error codes to a reader. A technician can hook the engine up to a code reader, or you can purchase one. The codes will disclose if the fuel injectors, or any other part of the engine, are not performing correctly.

How to fix it: Clean your fuel injectors. This will be a lot cheaper than replacing them. If you want to try and clean the fuel injectors yourself, make sure you have the right equipment. Replace Fuel injectors if the injectors cannot be cleaned or are damaged, then they may need to be replaced. Even if the driveshaft is nice and tight when you inspect it from under the truck, it may still be a good idea to take a closer look at the U-joints at the end of the axle points.

If the driveshaft and U-joints look fine. Double check the axles. There are usually two axles that connect the front wheels and back wheels to the truck. If they become bent or dented, it will cause vibration and shaking that increases in intensity as you accelerate. Another way to check to see if the driveshaft, axle or U-joints are at fault is to watch for any vibration changes based on how heavy the load is. If the vibration increases or decreases with changes in the amount of load, then the axles and U-joints are affected.

If it does not change, then it may be engine related. How to fix it: Inspect U-Joints and axles; a visual inspection might not be enough! You may need to remove the driveshaft and take a closer look at the U-joints. While you are checking the joints, inspect the axles closely and look for any dents or bends that may cause issues.

Take note of any wobbling with the steering wheel, because this can be another indicator of a bent axle. Replace joints by removing the bolts and nuts from the end of the drive shaft, then remove the shaft itself. The joints will remain attached to the drive shaft.

Spray WD on the joints at the end. After you have removed the U-joints, clean up the ends until they are nice and shiny. Then, install the new joints. You should see an improvement in shaking after the joints are replaced. There are two different kinds of transmissions: automatic and manual. Automatic transmissions do the work on their own, while manual transmissions rely on the driver.

If there are any problems with the transmission it may lead to your F shaking during acceleration and other engine issues. If the truck is revving higher than it normally does at lower speeds, this is a major warning sign. You may also hear a loud sound while accelerating. If this occurs, it may be time to take a look at the transmission. How to fix it: Check and replace fluids. Transmission fluid is vital for it to run smoothly and effectively. A dirty tranny fluid may cause issues.

Check the fluid and take note of the color. When the pan is off, look for any clogged lines and remove the clogs if there are any. Clean off any metals on the magnet in the pan. Check transmission. You might need a technician who can hook the code reader to the engine and run diagnostics to see if there is a problem with the transmission.

Or, you could have a mechanic look at the parts and test the transmission. It might be cheaper to replace certain parts rather than buying a whole new transmission. If you wish to replace the transmission yourself, make sure you have the right equipment to properly lift the transmission safely out of the truck without it falling or sliding.

Since transmissions can be complicated it would be ideal to have a technician on hand to help you with this task. The vacuum must be carefully controlled with several hoses in order for the engine to run smoothly. A torn or disconnected vacuum hose can cause an air leak which leads to various sensors getting confused, this may cause misfires and backfires.

Keep in mind that if there is a misfire that is confusing the sensors, a code reader can be used to help pinpoint the source. How to fix it: Check the hoses to make sure they are connected with no tears or cracks in them. Remove the damaged hose and install news ones. Replacing with stronger silicone hoses is commonly done as a solution. Brake caliper The brake caliper holds the brake pads and pushes them against the rotor to make the vehicle stop. Although rare, a stuck brake caliper can cause a Ford F to shudder when accelerating to speeds of 40 to 50 mph, and it may worsen as you get faster.

The steering wheel may also shake, especially when braking. How to fix it: Check the brake caliper by removing the tire and wheel and then inspecting the brake caliper. If the brake caliper needs to be replaced then you will need to remove the faulty pads and caliper. Putting used pads back on the truck may cause the caliper to seize again. The pads may also stick to the caliper and cause shaking.
