Thread: Clunking Noise

  1. #1

    Default Clunking Noise

    Hey everybody lookin for some advice. When I am coasting down the road and re apply pressure to the accelerator I Hear a clunk, almost as if there is play some where. I was thinking this may be my U joints but im not sure. Any ideas?

    thanks

    Easy way to tell if it's your U joints, go under your truck, grab your drive shaft and go to town, if there is any give. replace them. If no give, take a big screw driver and wedge it in there and see if there is any give, front and rear U-joints. They're only $20, better be safe then sorry, its worth the $80, instead of the $200 tow to the shop because you bust a U-joint in the middle of the street.

    Ditto to what Ippielb said, & while you're under there be sure and check the rear trans mount. They are known for coming loose and clunking every time you get on, or off the gas.

    Year make, and model will help a bit as well since some years the backlash on the rear differential gears was higher than others so it would allow for a clunk like you are describing.
