Sounds like a wheel bearing, but I've replaced it (with a Timken), replaced CV Shaft, switched tires around, no difference. Turn left; noise. Turn right; no noise. Notice it more at low speeds than high. Could it be rotor or caliper?

Another possibility is the power steering pressure hose. I believe there was a recall for that on some Rivieras. It produces a type of growling noise during low speed steering.

Ended up being a bad bearing on the left side, not right, even though the noise sounded like it was coming from the right. Thanks.
