Here's why:
* Roaring Noise: Wheel bearings typically produce a roaring or humming sound, especially at higher speeds. The sound is caused by the bearing components not rolling smoothly.
* Quieter When Turning Right: When you turn right, the weight is transferred to the left side of the car, reducing the load on the right front wheel bearing. Less load means less stress and friction on the bearing, thus a quieter noise.
Other possibilities, though less likely given the description, include:
* Right front CV joint: A failing CV joint can also make a roaring noise, but the noise characteristics might be different and not necessarily quieter when turning right. A clicking or popping noise is more common with bad CV joints.
* Tire: While less probable, a severely unbalanced or damaged tire could contribute to a noise, but it's unlikely to change significantly with steering input.
* Brake components: Worn brake pads or calipers could make noise, but typically this is more of a squealing or grinding, not a roaring sound.
Recommendation:
Do not continue driving the car with this noise. A failed wheel bearing can lead to a complete wheel seizure, resulting in a loss of control and a potentially dangerous accident. Have a qualified mechanic inspect the right front wheel bearing as soon as possible. They can diagnose the issue properly and perform the necessary repair. Ignoring it could lead to more extensive and costly damage.
