1994 B4000 drivetrain pop
Hello. My 1994 B4000 5 speed 4x4 single cab makes a consistent pop that seems to come from the back of the truck.
Whenever I take off in 1st there is a pop. When I shift through the gears every time I get back on the gas after shifting there is a pop. It is not immediate, the pop wont happen unless I press the throttle more than lightly.
The pop happens sometimes if I am slowing down with the brakes.
I have replaced the last ujoint, greased the driveshaft splines, and installed a new transmission mount. The pop is still present. I stopped using the parking break and it still makes the noise.
