Default annoying thumping noise on takeoff

everytime I take off in 1st gear I hear a light thump thump thump. it doesn't do it if I hit the brakes hard only on takeoff, also doesn't do it if I take off in second gear. sounds like a spare tire shifting or something
any ideas?

Take a pry bar and see if you can move the front of the rear cradle right where it bolts to body in front of the back tires.....there is a big soft rubber bushing in there that wears out and let's the cradle slap the floor
