Clunk/Click when backing up.

[jtz54]

I'm hearing and feeling a clunk every time I back out of the driveway or a parking spot. I recently had a sway bar bushing break and had new control arms and strut and engine mounts replaced. I figured the clunk would go away with all this work but it's still there. The Volvo shop checked the motor mounts and bushings but they thought it was the strut mount so I told them I would take care of it. After putting in the new strut mounts the problem persisted. I thought it was steering related but it clunks without turning the steering wheel just backing up. 99% sure the noise is coming from the front somewhere. Any ideas?
