I would start by checking ball joints, control arm bushings and making sure the CV joint itself doesn't have too much play. Even thought the boot is good, the joint can go bad. Check for play in the axle where it goes into the transaxle. The frame may have slightly moved in the accident allowing the axle to move around too much.
If I had to guess, I would say it has to do with the axle itself. When under a load, there is too much force on the axle to have a problem. Once you back off the gas, it freewheels allowing play to surface.
Let me know what you find.
