loud whining/whistling under deceleration 1st gen

fixed.

 

Well that's cool..
on a side note any constructive help?? Just trying to see if it's normal or if someone has/had the same problem.

 

A little more info on your truck, I'm assuming its either access or double cab, so pretty sure you have a 2 piece drive shaft & I'm thinking center (carrier) bearing, an '04 with 37k ??? That would be extremely low mileage for something like a Carrier to go out, how much of the history on this truck do you know ? Did you possibly check to see if its a salvage title ?

The only reason I say this is unless I really felt I knew the history of the vehicle , that 37K would make me suspicious meaning the truck has been wrecked & another instrument cluster(speedo) may have been installed, this isn't neccessarily bad if it is the case , but if it was & it wasn't disclosed it may or may not be illegal, depending on what state & it would probably lean more towards dealers selling salvage titled cars & trucks, get your VIN & register with http://www.toyotaownersonline.com & see what kind of history pops up on your truck, mines a 2000 TRD & all kinds of service records & data came up with what was done & where, pretty good info, anyway, from the sound you describe pretty sure smart money's on the center bearing on its way out, just like mine has been for awhile......
