* CV Joints (Constant Velocity Joints): This is a very common cause of this type of noise. When turning, the CV joints experience significant stress and a worn or damaged inner or outer CV joint will often make a rubbing, clicking, or popping noise. The fact it's only when turning right suggests one of the right-side joints is more likely the culprit.
* Sway Bar Links or Bushings: These components help control body roll. Worn or damaged sway bar links or bushings can create a rubbing or knocking sound, especially during cornering. Again, the right side is a prime suspect given the noise only occurs during right turns.
* Ball Joints: While less likely to produce a purely *rubbing* noise, severely worn ball joints can contribute to noises when turning, especially under load. A clunking or popping sound is more typical, but a rubbing sound isn't impossible with advanced wear.
* Steering Rack: A problem within the steering rack itself is less likely, but it's possible. A damaged rack can generate noises under stress during turning.
* Brake Components: While less likely to be purely a rubbing sound, a brake caliper that's sticking or a worn brake pad could contribute to noise, especially if dragging against the rotor.
What to Do:
1. Visual Inspection: Carefully inspect the front right suspension components. Look for anything obviously loose, damaged, or worn. Pay particular attention to the CV joints, sway bar links, and ball joints. Look for grease leaks (CV joints), cracks (bushings), or play (ball joints, sway bar links).
2. Test for Play: With the car jacked up and the wheels off the ground, try to move the components by hand. Excessive play in any of the suspension parts indicates a problem. Wiggle the wheels side to side and up and down. See if you can feel any resistance or unusual play.
3. Professional Diagnosis: If you're not comfortable performing these checks yourself, or if you don't find anything obvious, take your Alero to a qualified mechanic. They have the tools and experience to diagnose the problem accurately and safely.
Important Note: Driving with a damaged suspension component can be dangerous. If the noise is significant or you suspect a serious problem, avoid driving the vehicle until it's repaired. Ignoring the problem could lead to loss of control, especially at higher speeds.
