When traveling above 60kmh a hum comes from the front end, it doesn't get any louder with increased speed. I can't pinpoint any one side for the noise. I don't want to confuse you all with to many details but sometimes the noise is louder,sometimes quieter but only happens above 60kmh. I put it into garage and they said wheel bearing so had the fronts replaced and noise still there. They removed new bearings and put old back on and refunded me since they were okay. They tool a look in front diff, they said looked brand new and oil was in excellent condition. I recently read about advancetrac and how tires are important especially circumference measurements. I have bf goodrich on back and Goodyear tracker 2 on front(walmart). I know far from ideal but the circumference measurements are all with 3/4 inch of all 4 tires. Where should I start with getting rid of this annoying hum? Thanks
The hum could be being generated by the tires. I would move the rear tires to the front (as they are a different brand) and see if the hum is exactly the same at the same speed.
High speed hum can also be generated from the design of some types of brake rotors but I doubt that is the issue in this case.
From what you have described I would not have thought the problem would be wheel bearings so I am surprised that was the diagnosis before a more careful investigation was carried out. I would have tested the tires first. (I would not have put the old wheel bearings back in either after they had been changed).
Sounds like front wheel bearings.
Does the sound go away when swaying one way or the other?
If you way left and ot gets louder it should be the right bearing and opposite for swaying right

sounds like a hub bearing for sure, does it change when you are in 4WD?
SOURCE: can the front differential on
Do the other bearing & change the diff fluid
Then get back to us
Flush the Power Steering Fluid
& add Lubgard,just make sure it
isn't the honda one
SOURCE: My front end makes a loud humming noise.
Alignment will not create a sound by it's self. The most common cause of humming (especially if you have an agressive tread design)is a wear pattern in the tires...check for that or rotate the tires around & see if the noise changes. If it does then you know it's in the tires. & Not always, but most of the time a bearing noise will increase or decrease in intensity if you load up one side at a time by doing 35-50 mph & turning slightly to each side.
SOURCE: noise in front end, sounds
You say the rear wheel axles and bearings have been replaced, you mention nothing of the front wheels, you have the symptoms of a front wheel bearing being worn out, remove them and check for pitting in the bearing rollers or the bearing races, I am sure you will find a problem. Hope this helps solve your issue with the bearing noise.

They only replaced front bearings. The noise was still there so they they offered to put old ones back on and refunded me in order to save me money. I haven't looked at anything in the back since it appears to come from front. I FORGOT TO MENTION. They had truck running on lift but couldn't get it to present any hum
