ok.. 2001 short bed/cab 4X4auto

description:::::: sounds like a cricket.. little bit of a squeek..

location::::: sounds like its coming up right through between my bed and cab...

when:::: this sound ONLY happens in D, while im moving forward.. but ONLY when im coasting.. when i let off the throttle i can hear it.. when i get back on the throttle ... it goes away

ok so.. gimme some ideas guys.. just something that i can start to look at.. maybe some of you have had similar noises...

what i know:::: u joints are good.. and its not a bushing...


lets see who wins

 

I had a noise just like that once. Turns out, it was my fuel tank squeeking. On my truck, if you look down between the bed and the cab, you can see the forward end of the fuel tank. At the bottom of the bed down in that gap, there is a little lip that sits touching the gas tank (the lip runs the length of the front of the bed). Anyway, it looked like that lip had gotten bent somehow just a little bit, so it was actually rubbing a groove into my gas tank. Not deep or anything, but you could see where it was rubbing. I called a dealership about a new tank, and they said that a new tank was something like $400. Turns out, mine was not damaged enough to require a new one yet (the walls are pretty thick, and it had not rubbed very far through). They suggested I just lower it a little so it wouldn't rub anymore. So, I lowered the fuel tank from underneath by unscrewing the hanger just a little bit so the tank wouldn't rub on that lip/edge anymore, and that took care of the squeek noise. That was about 3 years ago, everythings been fine since.

Also, if you have hauled something lately, like rock or dirt, make sure there isn't any lodged between the bed and cab. Have had that happen too.

 

totaly different car i know but, but my 1988 porsche 944 had that exact same sound and it was the out put shaft bearing... could be somthing similar. didnt these trucks come with a 2 peice shaft at one point? maybe its a bearing somewhere in the tranny...

 

I have the same noise, though slightly inbetween a cricket and a bearing
