Got a wierd noise.
 

Whe im on the freeway just drivin and let off the throttle my truck will almost make this grinding sound. i cant figure it out cause it only does it on the freeway and not around town. does anybody have any advise on the situation.

easy to fix.......never let off the throttle :ha:

you need to determine if its comming from the motor, tranny of drivetrain......................try messing with it letting off and popping it into nutral and stuff like that

It only happens when i let off the throttle once im not on the throttle the noise goes away. it occurs when im barely pushin on the throttle to.

sounds like to me U-joints...............check yer drivelines out good and both front axles.....jack the truck up one wheel at a time

that sounds like u joints to me most likely rear drive shaft. your 8 inches of lift probably dont help matters:argh:

i know exactly what it is from first had experiance with that exact truck

Then if you know what it is please tell me cause all of my u joints are fine checked them today at work. and the wheel bearings seem to be ok.

what about the carrier bearing?

Ya im going to pul the front end apart tomarrow and take a look.

remem ber when your rear end went out? when you let off the throttle it did it to, its changing pinion angles from axle wrap, same thing that happened when i rebuilt your rear end, look at youru-bolts to see if there tight
