axles(wheels,cv) making weird noises

[jcrx]

My car:92 vx hatch w/ EDM b16a2 from a 93 civic vti
My problem:after I swapped the motor everything was fine for about three days then I was on my to work,stopped at a red and when I went forward it started;when there is torque on the axle ,ie accelerating all is well then when I let off the gas there is a thumping sound coming from the RF wheel I can't really feel it that bad but it is loud as hell.Anyone know what this is?cv bolt backing out or something of that sort I haven't takin it apart yet but I throw it on a lift and counldn't see anything but then again on a lift the wheels pull all the components tight so maybe that is why.
