When you put your car in gear and the front end shakes, but it idles fine, there are a few potential causes that could be at play. Here are some of the most common issues:
Problem with Driveshaft: If there's a problem with the driveshaft, such as a loose or worn universal joint, it can cause the front end of your car to shake when you put it in gear. The driveshaft is responsible for transmitting power from the transmission to the rear wheels, and if it's not functioning properly, it can cause vibrations and shaking.
Issues with Engine Mounts: Engine mounts are responsible for holding the engine in place and absorbing vibrations. If the engine mounts are worn or damaged, they may not be able to effectively dampen the vibrations caused by the engine, resulting in the front end of the car shaking when put in gear.
Defective Transmission Mount: Similar to engine mounts, the transmission mount is responsible for securing the transmission in place and absorbing vibrations. If the transmission mount is faulty, it may not be able to adequately dampen the vibrations caused by the transmission, leading to shaking in the front end when the car is put in gear.
Damaged Wheel Bearing: Wheel bearings are responsible for allowing the wheels to rotate smoothly. If a wheel bearing is damaged or worn, it can cause vibrations that are felt in the front end of the car, especially when the vehicle is in gear.
Imbalance in Tires or Wheels: If your tires or wheels are out of balance, it can also cause the front end of your car to shake when you put it in gear. Balancing ensures that the weight is evenly distributed around the tire or wheel, and any imbalance can lead to vibrations.
Faulty CV Joint: CV joints, or constant velocity joints, are located at the ends of the driveshaft where it connects to the wheels. If a CV joint is worn or damaged, it can cause vibrations and shaking in the front end of the car, particularly when putting the vehicle in gear.
Diagnosis and Repair:
To diagnose the exact cause of the shaking, it's best to have a professional mechanic inspect the vehicle. The mechanic can identify the specific component or issue causing the shaking and recommend the appropriate repairs or replacements. It's important to address this problem as soon as possible, as ongoing vibrations can cause further damage to other components in the driveline.
Preventive Maintenance:
To help prevent issues that may lead to front-end shaking when putting your car in gear, it's important to follow recommended maintenance schedules. This includes regular inspections of the driveshaft, engine mounts, transmission mount, wheel bearings, tires, and CV joints. Timely replacements of worn or damaged parts can help ensure smooth and vibration-free operation of your vehicle.
