Sounds like a flat but isnt

09 v6 automatic. 57k on clock.
was making the sound when i bought the vehicle.
starts when i take off and continues until i cant hear it.
sounds like a flat tire but isnt. took the vehicle to firestone had them balance tires and check for tread seperations, no problems with tires but i was told by the tech that balanced the tires that they were each unbalanced 3 ounces or more. just replaced brake pads as well and rotors seem fine after inspection. sound is very irritating because i dont want it to lead to more serious issues. it is a low whoop whoop whoop that sounds like a minor flat and accelerates as i speed up. not a loud roar but i need to know what it is. any of you experience the same thing? if so what could it be

If it's not the tire, wheel bearings make strange sounds when there bad.

I have enough for us all. We can dress up in leather and pretend we're going to a fashion show like the posers.

So you went ahead and bought it anyway? What did the owner/car lot/dealer think it was? Did they offer to fix it or so you could take it to a mechanic and find out what was making the sound?

I know you said you had your tires balanced, but did they check to see if your tires were cupped. The previous owner of my GT never rotated the tires. The rears were cupped. When I finally got them rotated to the front is when I noticed the noise got louder and then I got a vibration.

I bought it from a local five star dealer. Very reputable and reliable company. Or so i thought. But I bought the vehicle assuming the tires would atleast be balanced, however I was wrong. It's okay though guys, I'm getting new rotors, 4.10s, replacing bearings, and calipers soon. I think the bearings will do it.

Cupped tires are from bad shocks.

Can be bad shocks, also can come from unbalanced tires, uneven ware or alignment issues. Rotating your tires lets them ware more evenly and reduces the chance for cupping.

OP said that the tires were out of balance and he had them redone. My guess is that they are now cupped and unfortunately you can not fix them.

Your right though, I would also have the shocks checked.

OP when they rebalanced your tires, did they do a road force test on them?

They may have done the RFT in that time. It's a matter of having the right machine. They use the same machine to balance your tires. They lock your tire down and then another steel wheel comes down and puts pressure on the tire. Then they spin it at about 50mph. Sensors will give them a reading of 1 to 40 I believe. This test will tell if the tire is bad.

Here is a video on how they do it.

Well they said the tires were good so I don't think they're cupped

I guess if it were me, because tires are the easiest to diagnose and cheapest to buy. I would eliminate them as the problem first. I would go back to where you had your tires rebalanced and ask if they do Road Force Testing. If they do, and they actually did the test in your tires, then try to start eliminating other things. If they did not do the RFT then find a place that does and have it done. Most road noise problems are from bad tires.

Not saying this IS what your problem is. Just saying its the easiest to diagnose.

Front bearings take a pounding on our cars. If you think it might be a bearing, generally those are the ones that go out first. These are a pain to replace.

Drive shafts rarely go bad. U joints on the other hand do. U joints are pretty simple to do, with the right tools.

If your car is lowered then you shocks take a beating and prematurely ware out. You will have a rough ride. Take longer to stop. Your tires will wear unevenly and even cup. So IF your tires are cupped, be sure to also check your shocks. Personally I would spend the money and get new ones anyway. There are some real nice ones that improve handling and make your ride much smoother. It's a mod everyone should consider.

I'll be redoing the entire suspension system soon as far as cupped tires go I did ask if they did road force test they do. My guess is that it's with wheel bearings as soon as I replace the shocks and rotors I will be replacing the wheel bearings at the same time how hard are the front bearings to change

Honestly I wouldn't know on your car. On my old 98, it wasn't terrible but a PIA to get some of the bolts loose.

I think it was more in my head that I had to spend the money on repairs rather than upgrades. Lol.

Could a piece of your TPS have broken off inside one of the tires perhaps does the noise only come from one corner?
