I have a 2004 Nissan Titan and I have this "whoop whoop" noise, almost a cupping sound, that I can't figure out. I have had new upper and lower ball joints replaced, front end alignment, and new tires put on, as well as wheel bearings checked. Les Schwab has checked my wheel bearings twice, both times by different employee's. They said my wheel bearings are fine. They did say I do have a CV axle that may be going out but that would not be making the noise I am hearing. The noise can only be heard inside of the truck and it starts at about 10mph. If I turn left the noise stops. The faster I go the faster the noise gets. My truck doesn't shimmy when I brake or pull. It also shifts just fine. I am at a loss trying to pinpoint what it could be. Everything I have looked at online doesn't describe the noise except for a wheel bearing. So any ideas??? I don't want to keep replacing unnecessary parts and playing this hide and go seek game. Any information would be helpful. Also my interior lights, dome lights, don't work. All my other lights work except the dome lights. I keep blowing fuses so I am sure there is a short some where just not sure how to track it down. Any help with that would be appreciated as well.
