Replied in Doc's post about front end growling, but in case any of you missed it:
OK, so I too am having a howling noise from the front end. Started on Friday & I think it got progressively worse as the day went on.
So yesterday I jacked the whole front end up. Swear, from the driver's seat, it sounds like the tire rubbing on the inner plastic wheel well, but nothing rubbing.
When in N it doesn't make a sound, except for engine noise. Not so much in R either, but I click it into D and there is this low pitch growl. I cannot tell where it's coming from, but sounds a bit louder on the Driver's side than the Passengers.
Doesn't matter if the wheels are turned one direction or another or not, or really any variables like that, but it is tire rotation related. The faster the tires spin, the louder the noise. The 1 thing I didn't do, but I'm gonna this morning is try it with either wheel, keeping one from spinning, & see if I can narrow it to 1 side or the other.
It sounds like a bad bearing, not wheel bearing, but like it's coming from the tranny. Car has been shifting fine & I regularly service the gear box, every 30K. 127K on her now.
I'd appreciate any thoughts from anybody.
