With some time and perseverance you can disassemble the whole engine while it is still in the truck. That would be the worst case. If you can pull the pan, then each bearing can be inspected one at a time. This is a good place to use plastigauge and if you can still pull a torque wrench you can check each bearing this way. Looking for any damage or deformation of the bearing and crankshaft. What you may have is a wrist pin or piston that needs attention. That will require some help with the head. It is very heavy. Do what you can, don't hurt your self and take some time to heal. Use the truck for therapy. And have some fun finding out what you can do.
