I am new here and i have a 99 gt. No picture yet. When I am driving no matter how fast I feel a sort of rumble in the front end. I had a brake job done rotors turned on all four corners. No rumble when breaking. Thought it might be front wheel bearings but everything seems tight no movement. Please any help would be greatly appreciated. Thanks Joe

Can you feel it in the streering wheel? Does this sound happen at idle? Does it affect driving?

only can hear and feel while driving and you feel it a little in the steering wheel

mine started like that but very soon got bad, still havent fixed it, i think mine is a combo of alot of things, i replaced one tie rod end, and the other one needs replaced, that helped alil bit but also need alignment and tires, take off the front tires, look around, see if you can feel a wobble in the rotor while its jacked up

Yeah, i would try an alignment, and maybe new front tires. This happened on my first car, when driving over about 35 mph, it would shake profusely... new tires solved that.

It doesnt seem like a shake. It seems more like a whomp whomp whomp kinda noise. Thanks everyone for your input

It sounds like a tire is low on air. Or a X2 on the alignment. About what speed does this sound happen?

not sure what x2 means and the sound happens pretty much as soon as you start driving. I jacked the car up and tried to spin both front wheels but did not hear the same noise. Maybe it only happens under a load.

x2 means that he thinks its the alignment also, if you take it to a good alignment shop, they inspect everything under there too and will be able to tell you what is going on
