Knock when leaving a stop

Hey guys. I searched on this but its hard to search, I searched 'knock' but didn't come up with what I am experiencing.
When I take off from a stop, letting the clutch out normally, I hear a 'pop' coming from what sounds like is under/in front of me, more to the passenger side though. If I slip the clutch a little on takeoff, it won't do it. Also happens when I park on a slight hill with it in gear, when it comes back onto the tranny, it does it. I'm really not sure what it could be. Anyone know? Thanks

sounds like a motor or tranny mount(s) bad.


you can check by having someone put a load on the engine (partially engage clutch while parking brake set) as you watch the engine and watch for it to rise up or otherwise move.

Yeah I was thinking tranny mount but I wasn't sure. I'll check and see if it or the motor mounts look old or cracked or anything, and I'll do what you said to do.

Yeah its a CV driveshaft, but the CV was rebuilt recently and all the U-joints are new. I think it is a tranny mount, but right now its the least of my worries, as I still haven't figured out the grinding on deceleration. but when I changed the fluid in the transfer case and tranny, the grinding went away, then came back in a minute or so. So I'm thinking its a tranny or transfer case problem since new fluid shut it up for a minute.
