Check the U joints on the front driveshaft. Also see if the front differential is in good shape, with no play in the pinion gear input. Beyond that, if you have locking hubs, make sure they're either in or out all the way and the same on both sides.

What is the cause of a knocking from the front end of a 2000 Pontiac grand prix when driving at low speeds?

My 2000 Grand Prix would have a low-speed knocking noise coming from the drivers side as the CV axle was failing. The loss of lubrication in the CV Boots allows the joint to make a knocking/tapping sound at a low speed. If the knocking is coming from the engine compartment, then it could be an entirely different problem.
