I am getting a squealing sound some where . It is very faint and I can only seem to hear it inside the cab. If I roll down a window or open the door I hear nothing. It increases with speed and is most notable at lower speeds, say form 1 TO 25 or 30 mph. I can hear it better the closer I stick my head to the dash. I have manual locking hubs and so I know it's not in the front diff or axles. I have also jacked the front end up and turned both wheels, they spin free and with no noise. Thinking that it could possibly be in the Driveline or T-case I jacked the rear end up and stuck it in drive, there was no squeal at all. It is not related to RPMs and again it's only when the vehicle is moving and applying the brakes dose not effect it ether.
Dose anybody have some idea what the heck this could be?? I know it's hard without hearing it. But I need some ideas on this one!

Thanks guys!

 

buy a mechanic's stethoscope and probe around. post the part type or location and go from there

ummm? I would but it only makes the noise when I am driving down the road.

 

can't you have someone drive while you listen? or vice versa?

 

10-4 I will give it a shot.
