Severe clunking noise

Rear bearings will overheat and weld the inner race to the spindle. You'll have a severe wobble and very loud rumbling sound. You will also notice a lot of play in the wheel when you tug in and out on the top of the tire.

Is the noise coming from the rear or could it be in the front?

Look for uneven front ride height. If one side is an inch or more lower look for a broken coil spring. They can make a horrendous noise.

Next, check the left and right engine mounts to see if the engine is sagging on one side. That can cause the vibration damper to rub on the plastic splash shield or the half shafts to bind as they rotate.

If you can't find anything loose with a visual inspection, you might try a tool called the "Chassis Ear". That is a set of six microphones, a switch box, and head phones. You clip the microphones to suspect points, then drive around while listening with the head phones. You might find this tool at an auto parts store that borrows or rents tools. Be aware that many mechanics have never seen or even heard of this tool but most new car dealerships have them.
