Humming/whining noise in 4WD during decel
Vehicle listed below is what this is about.
35 mph it seems to be the loudest. Noise dissappears as soon as I shift out of 4wd. My biggest suspect is probably u-joints, but I'm hearing two different noises, and not all necessarily at the same time. I haven't really noticed the sound until it has gotten so ridiculously cold out. I'm also thinking front pinion bearing. I guess I'm kind of curious if this is just normal and I never noticed it before, because both my KJ and YJ made growling noises in 4wd, and the KJ did it right from the factory.
I'll be damned if I'm going to get my ass underneath there and start playing with stuff either with how cold it is. I may go and get a T-case flush and front diff flush since I haven't had that done in awhile.
