noise from underneath

[P.J]

i recently just jsut got the wierdest noise
its a little whine coming from below the front seats. i was thinking it might be the chain in the transfer case perhaps someone has experienced this before and could help me out and diagnose it the whine increases with the rpms so i aint sure what so ever what i can be in park and in neutral there is no noise on when its in gear

This sounds kinda like what I am experiencing. When my truck hits 2500 RPM's or higher I get a whine sound coming from somewhere under the truck, sounds kinda like in front of the cab. I will let you know if anyone can figgure it out. Hopefully someone will come along and help us

Cheers
