Probably safe to say your growl is a result of your incident. Something got tweaked and probably wheel bearings or cv joints. I would lean toward the inner cv joint considering your growl pops up while accelerating or decelerating. Trouble is I've never heard the noise they make described as a growl. Usually they create a clunk or bump noise when you accel or decel. I would put someone in the drivers seat familiar with auto mechanics and get their opinion.

To check the bearings you can jack that side up (on a jack stand) and spin the wheel. Should spin smoothly with no grinding noise. Check for play in the bearings by wiggling the wheel from top and bottom and sides. Should have little or no movement. To check the cv joints try to twist the drive axle and watch for play at either end. Should be none. You may not see any and they could still be bad. The only way to know for sure is to change the driveshaft and cv joints as an assembly. Eliminate other causes before that step. Keep in touch.
