Sounds like a classic wheel bearing issue diagnosis. Just because the noise is more prominent when turning left doesn't mean it's automatically the left bearing though. Get somebody else to drive while you sit on right and see if it sounds different. Of course the conventional wisdom is to replace both of them.
I'm pretty sure at this point it's the RIGHT wheel bearing, as the wife sitting in the front passenger seat noted the noise as well, and she's HORRIBLE and noticing anything unless it's smacking her in the face! :happy175:
guess I'll yank the plow and get see about replacing that bearing today.
correct me if I'm wrong but its:
pull caliper
pull rotor
disconnect ABS sensor
undo axle nut
undo 3 flange bolts
pray and yank assembly off
assembly is reverse of disassembly
