2001 ex. 180,000 miles.

When i drive it, i hear alot of road noise/humming from the front end. It doesnt seems to be the engine, cause i will step on it, engine revs up and the nolise stays consistant with how fast im going, it does not change with rpm.

Tires are not brand new, but are in good condition

I have this noice on my diesel cause its lifted and has big off road tires, but i wouldnt expect this noise to be coming from a car.

Any suggestions will help out alot.

Thanks
