jultering when i let off acceleration or changing gear

[twinkle-starlet]

dunno whats wrong with my car had it on a corsa turned out to be the driveshafts i think ??
MY starlet is jultering when i let off from accelerating quite harshly any ideas what it could be ???
someone said gearbox
driveshafts
??????????????
gears go in ok so no problems there at the moment so guessing its not the box??? hmmmmmm i gotta take it off the road next month to do :
clutch
uprate brakes
hybrid
internals
few other lil mods
spray front bumper and bonnet

what do people think the problem is to add to my growing list !!!
