U-joints going?

[thos]

I've been noticing a "clicking" sound when I engage the tranny from park and sometimes - not always - when going from a full stop. Not a "clunk" but a mild "click". Is this the begining of a u-joint pbm?

Could be U-Joints or a rear end problem. Get a friend and have them put the e-brake on and shift the truck from park to Drive to Reverse etc while you look at the driveline for the noise.

Oh you might want to block the wheels too for added safety.
