Mark (or is it Mike? See the header below) - This is literally a shot in the dark, but check this out - It sounds like the tick comes when you have the rear of the car loaded a bit (accelerating, "bottoming out" at the base of a long dip, etc.) Has your car been lowered? The reason I ask is that I had a similar experience after I lowered my car down 1.75" in the rear, and 3.5" in the front. When the rear squatted down, I would hear a noise like a tick. It turned out that the sheet metal dust shields below the trailing arms were rubbing on the drive axles. There was a shiny band on the axles, and a wear mark on the shields. The fix was to bend the edge of the shield up a little in the local area above the drive axle to create some additional clearance. I hope that helps.
