I have a 2008 Silverado RWD WT 111k miles on it. I can hear a loud clunk (the whole trucks shakes, it is really loud) when jumping on gas from full stop. It does not happen when I am easy with the gas. I suspect the sound comes from the driver side. Any idea?

Usually if you have a slip yoke. not saying you do. there is a carrier bearing that holds the two shafts in place. That can cause these noises and clunks. grab the shaft and try and move it around. shouldn't be able to.

Does it sound like it's coming from the drivers side front or rear of the truck?

I just went through this. For me it was a trans mount cross bar that needed to be re-torqued at the frame rails. Just enough play in it to slide around when under a decent torque load. Like when goin from fwd to rev and gassing it. Or accelerating up a hill from a stop.

It was a bad driver side motor mount; I replaced it last weekend and the cluck is gone!
How tough of a job was this? I'm about to tackle it this weekend. Any big "gotchas" that I need to know about (special tools, parts, tips/tricks)?

Quite hard but doable ; U need a long socket extension, ramp, big shop jack in order to lift the engine up a bit, good penetration oil etc. There is good videos on utube. Good luck and be careful.
