    When I depress the accelerator from slower speeds, I hear a constant high-pitched whine from the front left. It will disappear if I lay off of the accelerator, and won't return depressing the accelerator again. Basically, accelerate - whine appears. Lay off accelerator- whine disappears. Depress accelerator gently- whine stays gone. Depress accelerator kind of hard again- whine returns. I though at first it was at higher gears but it comes when I put it in first and accelerated. Wheel hub was replaced three years ago.

    Any ideas?

    Automatic or manual?

    That wouldn't account for the noise disappearing when you let off since that doesn't change the loading on the joint in 2wd.

    Are you sure it's a whine and not a rattle? When the exhaust heat shields get loose it can behave similar to what you're describing. Check to see how many of the little clamps are broken.

    Definitely not a rattle but a high-pitched tone. I secured all of the heat shields last year when I redid the exhaust and they're still secure. I've also been chasing down an ABS/VDC/SLIP lights problem . I don't think they're related, but putting the X on stands today to check everything again.

    Sounds like a front wheel bearing, especially if you are also having abs/vdc/slip lights.

    That's my primary culprit. Was checking and ruling out everything else, because looking at how-to's and the FSM, it seems like a pain to replace.

    I've also noticed the tires moves considerably at 3-and-9, but not noticeable at 12-and 6. Tie rods? Just tie rods or that and wheel bearing?

    Could just be slack in the rack. You have to watch the tie rod as you shake the tire to see if the rod moves with the knuckle. Could just be that you're moving the rack since the steering wheel may not be locked.

    I replaced the front left wheel assembly, and nothing changed. I still have the ABS/VDC/Slip lights, still makes a high-pitched whine, and also hearing a whoomp-whoomp-whoomp sound.

    Is it definitely only when moving? Have we ruled out timing chain guide whine from the engine? That would follow RPM’s and sounds like a supercharger.

    When I replaced my worn out wheel hub assembly it fixed a clunk I was having while turning into uneven driveways. Never had any whine or high pitched noises from that.

    Yeah, only happens when moving. I'm certain it's not the timing chain. The whine intensity doesn't change with the rpms.

    After changing the FR wheel, I cleared old codes and rescanned with my BlueDriver. Now I'm getting C1103 (FR sensor 1), C1104 (FL sensor 1), C1163 (steering angle safe mode), C1203 (ABS system), and P1856 (VDC system). Ugggh.

    Don't know why I'd be getting a C1104 when I just replaced the sensor with a new one.

    Check to make sure the wires weren't damaged at the plug when you changed the bearing.

    Are you certain the noise goes away when you let off and ease back on the accelerator. Throttle position shouldn't affect a wheel bearing outside of what speed you are traveling.

    Had you pulled those codes before you replaced the bearing?

    What type of oil filter are you using? I’ve noticed with some filters you develop an engine whine as well.

    I forgot all about that.... I had a Purolator filter so that. Switched to WIX/NAPA Gold and haven't had that trouble since.

    Update. I replaced the drive belt and the noise is almost gone. I checked and the belt seems to be centered, but the noise is faint. Could the tensioner be bad? Or a pulley? If so, which one most likely?

    Pull the belt and check for play in the pulleys. But if one is bad, it's best to replace both. Get the full tensioner with pulley, not just the pulley. Folks don't realize that the spring in them ages out and they get weak.

    Checking for play was on my mind to do when I changed the belt, but somehow slipped.

    So, months later.... I removed the belt, checked the tensioner pulley assembly, no play. Put the belt back on and it still makes noise between 2.5K and 3.5K. If I accelerate hard, I get a higher pitched whine, like a whistle. Any ideas?
