03 Explorer Whine

[Chillie]

03 Explorer 4X4 auto; 10K ago front wheel bearings, this week rear wheel bearings and hubs, ebrake pads.front lower ball joints, front pads and rotors,
Now that it is quite there is a whine in front end, higher speeds less whine, My mechanic thinks it is the diff. is i turn wheel to left the sound is louder, There is also a different sound on right, what do you think. Diff or the front wheel bearings? I want to fix but tired of chasing my tail. also all 4 tires the same.

Unless you got some seriously cheap front wheel bearings 10K miles ago, or they were incredibly poorly installed, it seems implausible that the wheel bearings would be the problem.

Agree! Whining which resembles singing more than the "rumbling" which tapered roller bearings tend to produce, is likely being produced by gear teeth. Ring and pinion gears "singing" change pitch, and usually, loudness, with vehicle speed, but are affected almost not at all by the differential gears turning (which happens when the wheels are not straight-ahead). So, I would lean toward the differential gears; in any event, if the whine IS gear-produced, the "fix" is more "heavy-duty" involved than wheel bearings. If the noise is not excessive, one could live with it for quite awhile.

Check that the housing has lubricant in it before anything else.....it would be rather disheartening to begin disassembly of an axle to find the problem originated from lack of oil! imp
