What is the speed of the knocking?
Wheel speed could be axle bearing (a very short lived situation before it breaks or burns) or inside the diff. (also a short fused item)
Faster by 3 or 4: U joints.
I'd get this thing on a lift and have someone look at it while everything is turning. I'd suggest safety glasses, as something is about to let go.

Since you just had work done, time to recheck anything that was unbolted.
I take it this isn't a knock that starts slow and builds in speed as you accelerate? If it knocks a few times as you get underway, look for loose mounts or crossmember. If it builds in speed, look again at driveshaft and axle.
This sounds like a minor problem now, anything you can do to speed the discovery will most likely save you a major problem or worse.
