Ladies and Gentlemen, need some help please. Over the last week or so, I have a new noise coming from the rear of my car. It is a very low pitched, oscilating at times, noise that increses in volume and rate of oscilation with speed. I have inspected my tires and rims, no damage founds. I re-torqued the lugs, all were fine. I checked infation, fine as well. Tire wear lookes even. I don't remember hitting any killer pot holes and gave the spanish inquisition to my partner, because he had the car recently for a day, no hits. <p>The only thing I found was a post on the angle gear posted by BlkT5inNM in which something similar is described. Does anyone else have any ideas on what this noise could be. Of course I'm out of town and nowhere near my volvo dealer. Will it hurt to drive 300 miles home? And if I want a loaner, will surely be at least two weeks before they can see me anyway. <p>Thanks for everyone's help in advance. This is actually the first thing that has gone "wrong" with my '05 since the '04 was repurchased and replaced by Volvo.
