I have a 2004 Deville. Rotated tires. I now have a noise left front. It is louder at speeds uder 25 mph. Braking may increase noise. Inspected brakes. Pads ok, roator clean smooth. There is no pedal shake. If the road has rolls in it. It seem to go away with negative g's. I drove around in circles and found left turns are quieter. There are just so many things it could be. What the heck wouls moving a tire there cause? Help...Mike Today I rotated the right front. It seems to have some louder rolling sound.

Yes Iam waiting. I had to get my question unocked. Somehow a oil presure and tire rotation questions are the same. They are not. Yes I would like the question answered asap.
Hello & Welcome to JA,
Noises are sometimes hard to nail down. The noise you speak of is most likely a drive axle (on the left side) or a wheel bearing. Usually a bearing does get louder with sound but not always.
To change both parts at the same time is costly.How can I troubleshoot? How do I proced?
The best way is to put it on a lift,have a vehicle operator rune the car to 40 mph & a person under the car listening side to side & comparing noise.
Before I heard back from you I did my own test. Moved the tires back to their orginal positions. The sounds are much softer or gone. What do I do next. The lift thing? I do need to know the fault. My thought is tire balance, 4 wheek ailnment or two bad wheels. Any ideas?
Check the tires & wheels for trueness in being round ,no flat spots,& the wheel must be true in all measuring respects (parallel, center,& or no bends)
replace the faulty part.
