Default Re: 2006 LS focus, wup wup wup sound front left.

To add, tyre noise can change with temp as they warm and soften so if it's only there for the first few minutes of a drive, it does point to tyre.


What about swerving (carefully!) from side to side to load and unload the wheel bearings?


I've also had a flat spot (caused by a brake lock) on the inner side of a front tyre that made a wup wup sound, but only when that tyre was unloaded in a turn to that side. Under normal or increased load it made no sound.
