Been chasing a chattering sound at low speeds from front end (metal on metal sound) and 50-60mph vibrations. Does this look like excess play in front driveshaft slip joint? I would think it has to be! Let me know.
You can either have that driveshaft repaired locally or purchase a new one from Tom Woods.
I have found that many times purchasing the new heavy duty driveshaft is cheaper than getting the driveshaft repaired.
