Ok....lets apply a little practicality.
The inner rod end threads onto the rack. You only need a tool to turn it and apply the proper torque. The "claw" washer is staked over the flats on the inner rod. The purpose is to prevent turning or loosening of the inner rod. A simple 10" pipe wrench can easily apply the 56 ftlb torque, which is not a high torque level.
Gen2, although not the same part, install in a similar manner.
Try not to overthink this.
Consider. If the outer tie rod end needs to be replaced, then the inner probably also needs to be replaced. Both ends have seen the same conditions and mileage during their time on the truck. Sure the inner rod end has a bit less movement, so the wear rate will be a bit slower. Also, if the truck is apart to replace the outer, then it cost less to replace the inner at the same time. Otherwise, you will need to do the work a second time for the inner rod ends paying the time and labor costs again. Labor rates at shops run over $100/hr.
Stepping over $$ to save pennies.
Remember, you will need a front-end alignment after this work is completed.
