    Hi All,

    I have a 2004 Tacoma Double Cab TRD with 89k miles.

    Recently I began to hear a "whomp whomp" from the front end. It appears to be coming from the passenger side by the wheel. It sounds like plastic rubbing but I can feel the vibrations in the floor. No vibrations can be felt in the steering wheel. No vibrations when braking and it does not pull to either side. It is most easily heard after accelerating through 60 when I release the gas and coast. As the vehicle slows the sound can be heard but if I accelerate the sound either goes away or is drowned by engine noise (not sure which). At other times though it is there all the time. Usually I need to get above 50 first to hear the sound. The whomp whomp is faster at higher speed and will slow as the vehicle slows. It is indistinguishable below 20.

    Ideas?

    I thought wheel bearing but when I had it up on a jack tonight I didn't notice movement. I spun the wheel and no sounds other than the calipers which appear to be the same from side to side. I put on the spare and no change in noise. I'm stumped...

    Thanks!

    bump...

    Anyone know if a bearing would show itself as an intermittent grinding noise?

    Was a PreRunner, now it isn't
    Have you tried moving that tire to the back and see if the sound moves with the tire?

    Could be those little rubber (?) flaps that attach to the frame , kinda like a splash shield, you know by the starter on pass side, maybe came loose, they are heavy enough to make some noise if enough wind gets to them...:notsure:

    Sounds like front diff issue to me....had the same noise on my 2003 Tundra which eventually showed itself when my front diff engaged but wouldnt pull (grind grind grind) one day.

    Thread is a little old, maybe he lost his 4wd and ditched the truck. But then again he never said it was 4wd...just guessin here.

    Hey guys, figured out my issue a few months ago. It was a bad left rear wheel bearing. Finally took it to my mechanic and he diagnosed it after putting it up on the lift. He said it is common for bad wheel bearings to present themselves by transmitting the noise through the frame to other places. Weird eh? Anyway, changed it out and haven't had a problem since then.

    Thanks for the follow up! The symptoms sound exactly like my issue. However I had the rear wheel bearings and differential replaced 20k miles ago. Hopefully one is not already bad but gives me a place to start looking!
