Hello, I'm a certified automotive technician with over 15 years of experience in the industry. I've seen my fair share of car issues, and *shimmy* is definitely one of them! It's a common problem, but understanding its root cause is crucial to getting a reliable fix.
Let's break it down. A *shimmy* is a vibration in the steering wheel that usually intensifies at higher speeds. It can be a subtle quiver or a full-blown shake that makes it difficult to control the vehicle.
The culprit? A misalignment between your car's steering, suspension, and wheels. Here's how:
1. Worn Steering Components:
* Steering Tie Rods: These connect the steering rack to the wheels. Worn or loose tie rods can cause the wheels to wobble, leading to the shimmy.
* Steering Knuckles: These are the parts that connect the tie rods to the wheel hubs. If they're worn or damaged, the connection between the steering and wheels becomes compromised.
* Steering Rack: This is the component that translates your steering wheel movements into wheel movement. A worn rack can result in uneven steering and a noticeable shimmy.
* Wheel Bearings: These allow the wheels to rotate smoothly. If they're worn, the wheels won't spin evenly, contributing to a shimmy.
2. Suspension Issues:
* Ball Joints: These allow your suspension to move freely, connecting the control arms to the wheels. Worn ball joints can cause excessive play in the suspension, resulting in a shimmy.
* Control Arms: These support the weight of the vehicle and connect the wheels to the frame. Worn or damaged control arms can disrupt the suspension geometry, leading to a shimmy.
* Shocks and Struts: These dampen the vibrations from the road. Worn shocks or struts can allow excessive bouncing, which can transfer to the steering wheel as a shimmy.
* Springs: These support the weight of the vehicle. If they're worn or damaged, the suspension can sag, leading to misalignment and a shimmy.
3. Wheel and Tire Problems:
* Wheel Alignment: This refers to the angle of your wheels in relation to each other. An improper alignment can cause uneven wear on your tires and lead to a shimmy.
* Tire Wear: Uneven tire wear, often caused by poor alignment, can lead to a shimmy.
* Tire Pressure: Incorrect tire pressure can affect the way your tires interact with the road, leading to a shimmy.
* Bent Wheels: A bent wheel can disrupt the balance of your tires and cause a shimmy.
4. Other Possible Causes:
* Loose Lug Nuts: Loose lug nuts can allow the wheel to move freely, resulting in a shimmy.
* Damaged Brake Rotors: Warped or damaged brake rotors can cause the brake pads to grab unevenly, leading to a shimmy.
* Suspension Modifications: Aftermarket suspension modifications, if not done properly, can cause alignment issues and lead to a shimmy.
Diagnosing a Shimmy:
* **Inspect steering and suspension components:** Look for any visible signs of wear or damage.
* Check tire pressure: Make sure all tires are inflated to the correct pressure.
* Examine wheel alignment: Ensure the wheels are properly aligned.
* Test drive: Drive the car at different speeds to see if the shimmy is consistent or if it gets worse at certain speeds.
Fixing a Shimmy:
* Repair or replace worn components: This might involve replacing tie rods, ball joints, control arms, or other suspension parts.
* Adjust wheel alignment: A proper wheel alignment can often fix a shimmy.
* Replace tires: If your tires are worn or damaged, you'll need to replace them.
* Check brake rotors: If the brake rotors are warped or damaged, they'll need to be resurfaced or replaced.
Remember: A shimmy is often a sign of a larger problem. Don't ignore it! It's best to have a qualified mechanic diagnose and fix the issue to ensure your car's safety and performance.

The most common reason for a car to shake is related to tires. If the tires are out of balance then the steering wheel can shake. ... If your steering wheel shakes while you are braking then the problem could be caused by "out of round" brake rotors. This vibration can also be felt through your brake pedal.
