Wub Wub noise when Turning Left

[samueljerri]

Vehicle: 2003 Ford Expedition EB 4x4 220,000KM

I get a wub wub noise when turning left (and slightly, very quiet to the right).

Here's a video of the noise: https://www.youtube.com/watch?v=RS7y0qCKPR0

Skip to about 1:40 to get a clear read on the sound.


Now, I initially thought it was a bad bearing, so I got both of the front hubs changed. But, the problem is still there.


The mechanic checked the CV boots, tie rods, ball joints... everything is a-ok by him. He did discover that the right seal for the front diff was leaking (this is a LSD vehicle). Though I'm not sure if that's the issue...


Now, my brother-in-law said it could be a bad tire. I just put on new Wrangler's about 4000KMs ago... Maybe a tire rotation to isolated the noise?


What else could it be? I'm at a loss here :\

Right wheel bearing.

Makes noise when you turn left and load it.


I will say that I had one that acted exactly the opposite, though....but what your truck is exhibiting is a classic bad wheel bearing noise.

usually wub wubs are caused by a loose skrillex bracket

I replaced my skrillex bracket with an aftermarket bassnectar one and now it drops fully.

Is the wheel bearing lock nut tight enough? Was slightly loose on my Nissan, made it sound like a bad bearing.

A damaged, bent rim also produces the wub-wub sound.

You realize you have bearings on the back wheels, too, right?
