I have a low hum coming from the front end, just want to make sure it's nothing else.
... a low hum, can't hear it much at slow speeds, once I'm doing about 20 km or more you can hear it but doesn't really get louder as you speed up. There's no clunking, or any other noises, is there anything else that could be causing the "Humming"?
I'm thinking because I hear it now, I'm getting all **** that it could be something serious approatching. !

 

Wheel bearing! And fill out your sig or profile so we know wth you drive.

 

thanks,

 

Now that we know it's a 4x4, Check the front end fluid level and your axles.

 

I did a complete front and back diff. fluid change a few weeks ago. The Noise was there before & after.
It's not really loud, but it is noticable. Noticed it maybe mid summer, no change in sound since then. You would think if it was bearings, it would have gotten worst.

 

you can rotate your tires from front to back and see if the noise change.

 

I still haven't found this front end Hum/noise. I have ruled out the Tire Hum, as there is no change in noise from dry, wet, snow covered surfaces I'm driving on. If this was a bearing going bad in the front drive-line, would it have not blown apart by now?? The noise has been there for 3 months now!!

 

it depends on how much you use the truck. pick the front end of the truck off the ground, jam a bar underneath the tire. lift up. it wouldnt doubt that you will feel the tire go up before you feel resistance. thats a definite sign of a bad wheel bearing. even the humming is a good call on a bad bearing.
