Clicking sound in N or D coasting around 40km/h

Noticed with the 93 wagon there is a clicking sound around 40km/h then goes away. As soon as you tap the gas it goes away. Shifting to N or D doesn't effect it. I can shift to N and rev the motor still clicking. Not very loud just it's there and it is bothersome.

Some notes on the car. It has close to 330,000km, got low mileage wrx struts tops hats and all so head to toe, two new front cv's all done like 10,000km ago or so, replaced the driver side ball joint, unsuccessfully replaced the passenger side balljoint because the pinch bolt snapped, so it has been riding the balljoint with a broken boot I also noticed some play in the hub. So until i replace that balljoint can't really see if that is the issue. Does that make sence though can the balljoint create that noise right at that speed?
