Hey guys,
My truck has recently developed this noise that sounds like a tire rubbing a fender liner or even a wheel bearing (for lack of a better description). Sound is the same in 2wd and 4wd.
The sound is directly proportional to the speed of the tires, can hear it from 20MPH and up. Slowing down, coasting, and accelerating. Sound does not change turning left or right (taking front wheel bearings out of the question i would think). Its very difficult to tell what direction it is coming from.
Changed the fluid in the front and rear axles (they needed it anyways) the Diffs both looked in good condition, no metal in oil or anything.
Checked out all 4 wheel bearings, no play, no grinding when turning by hand.(Also put a stethoscope to them, no odd sounds)
Front axles both have new ujoints (also did all ball joints) about 10k ago.
Dropped the driveshaft. No play in rear drive shaft u joint and the center bearing turned smooth. Took it for a drive with no driveshaft, in 4wd, and the noise still persisted.
Put the truck on a lift and ran it up to about 30mph, could not replicate the noise.
The unknowns I have left
Tcase- fluid looks good, but what kind of sounds would a bad tcase make?
Trans- Shifts as it always has, Fluid looks good
Tire noise? gonna throw a different set on this week hopefully to test this theory, even though it doesn't sound like tire noise to me since it happens on all ground (snow, dirt, pavement, etc.)
Maybe I missed something in the differential? Bad pinion bearing?.
Was also considering taking the front wheel bearings off to better inspect them by hand. But that wouldnt be for a couple weekends.
What am I missing? This sound is driving me bananas!
Thanks for the help.
