* Balance Issues: This is the most common and easiest to fix. Unbalanced tires or wheels are a primary suspect. The wobble is often most noticeable at low speeds because the imbalance is amplified at slower rotation speeds. Get your tires rotated and balanced.
* Tire Wear: Uneven tire wear, particularly cupping or feathering, can cause a similar wobble. Inspect your tires carefully. If the wear is uneven, you may need new tires.
* Wheel Bearing Problems: Worn wheel bearings allow play in the wheel assembly, which can manifest as a wobble, especially at lower speeds. A mechanic should be able to detect this by checking for play in the wheels.
* Suspension Components: Worn ball joints, tie rod ends, or control arm bushings can all contribute to steering wander and wobble. These components are crucial for keeping the wheels properly aligned and stable. Worn parts allow excessive movement, leading to the wobble.
* Steering Rack Issues: Problems with the steering rack itself, such as worn bushings or internal damage, can lead to play and wobble. This is less common but a possibility.
* Alignment Issues: A misaligned front end can cause steering wander and wobble. An alignment check is crucial to rule this out.
What to do:
1. Start with the simplest and cheapest: Get your tires rotated and balanced. This is the most likely fix.
2. Inspect your tires: Look for uneven wear patterns.
3. Visit a mechanic: If balancing and tire inspection don't solve the problem, a qualified mechanic needs to inspect the suspension components, steering rack, and wheel bearings. They have the tools and expertise to diagnose the problem accurately.
Don't ignore the problem. Driving with a wobbly steering wheel is unsafe. Get it checked out promptly.
