what could a humming noise from my rear end be?

Question

Its a Ford F-150 2-weel drive,when u are gowing down the road theres a humming noise coming from the rear end of the truck?

Answer 1

i own a repair shop,and it sounds like it may have a wheel bearing going bad on it,,its pretty common on all truck to have to replace a bearing every once in a while,,you can jack it up ,nd check the free play this might help determine it a little,,also look on your tires make sure you don't have that is wearing out uneven this will cause a sound too,,good luck i hope this help,s.

Answer 2

If you are running aggressive tires on the rear, that could be the culprit.

If its not the tires, you will want to inspect the rear differential. There is a chance that a bearing (such as pinion bearing, or one of the differential side bearings) is going bad.

Have you checked the fluid level in the rear differential? If its gotten low, or if the truck has high miles the ring and pinion gear could be well worn, and this too can cause the gears to make noise. Or if someone has changed the rear gears, and used a set of used gears this can cause noise since its nearly impossible to get the used gear-set to align perfectly in its old wear pattern.

Have the rear end inspected, and check the differential for excessive play, or slop.

Answer 3

when was the last time you rotated your tires? If you don't rotate them enough, you can cause the rear tires to get 'cupped' expecially in trucks with lighter rear ends. The back tires start to wear in a funny patter on the inside edge, you can tell if they are cupped by running your hands over the inside edge of the tire and feeling for flat spots. If it's bad enough, it might look the flats spots like a soccer ball might have.

Answer 4

A noise from the rear is called a fart, could be the rear end pinion is out of adjustment.

Answer 5

You either don't realize that your getting a rim job by another man but hopefully a woman or your rear end in your truck is going out.

Answer 6

Sounds like wheel bearing or do you just put new mud tires on the rear? Good Luck!

Answer 7

tires (usually from not rotating)
wheel bearing (usually from not repacking, unless they're sealed)
differential (dogging the truck or leak or mechanical failure)

These are in order of expense and logic. Tires are usually the cause and the easiest to remedy. Rotate as per maintenance schedule next time.

If you listen at higher speeds you can tell who rotates their tires and who doesn't! Hummmmmmmmm..........

Answer 8

The humming noise from my rear end smells like burnt grease.......

Answer 9

That is probably humming coming from the tires.

I just hope you never end up in prison.
