car: 2009 SR D4D dualcab diesel
high pitched rythmic squeal. sounds like metal on metal with dirt inbetween
rythm is synced to road speed - not revs
source is dominant on left hand side, and appears to be coming from left hub, but as ive only been able to test with car moving, (and the fact the front diff is offset to the left)
only occurs in speed range 5kmh - 40kmh
much more likely in hot weather or extended driving (read: it needs temperature)
on the above point, i had a situation driving to albany and when i stopped at Williams for fuel, the weather was warm, with warm air, and the sound was really loud, yet by the time i got to albany where the air was cold, the noise had gone.
if i go to carwash with an underbody spray, it disappears for up to an hour (or the next drive).
so far, based on other squeaks ive found caused by dirt getting in between metal (rhino pioneer rack, tailgate latch), and fixing with the tiniest bit of lubricant, i feel its dirt from driving through mud that has got somewhere. ergo - i dont think its serious. its just embarrassing.
ive pulled the hub off and greased the metal cover on the cv which fits there coz i first suspected that. plus greased the spacers that exist on non-abs models still there. when i pulled the hub off i could see evidence of rust getting to that hub a little where as the RHS hub was fine. i wont try explain the rust look/locations - ill prob just take the hub off again some time, inspect it better, take more pics, apply more grease.
