Developed a shake/shimmy during take off

Can't figure this out. I've got it narrowed down to a few things from what I've researched but was hoping to get a better opinion. It's an 05 Tj manual with 8" lift . T- case drop SYE and cv driveshaft. It starts to shake vigorously when I let the clutch and and start to roll but it goes away as soon as I get up to speed. It's only in the start right when the clutch disengages . I've been told it could be a bad clutch but I know my t-case chain is stretches and has slot of play so could that be it or u joints? Rear cv has a little bit of play but not a lot. The shake wasn't there this morning but comes and goes throughout the day
