Well that was easy. Called the local Ram dealer and asked for part #68448027AA, they had it. 5 minutes later had it in my hand. Came home and 5 more minutes later it's in. Inspected all the plastic actuator parts and nothing looks cracked. Also found a foam "donut" around the left rod was out of place, and probably why that side rattled. I just slid it to the right under the sheet metal, like the other side was, and now it's quieter. Lock also seems a bit quieter in operation. BTW I had disabled auto-lock shortly after bringing the truck home. I suspected it was causing the truck to lock on it's own on occasion.
