Order to replace things on the front suspension

[NoCalMer]

My 300D needs a front end alignment and new tires. I want to make sure I have the right things replaced before paying for an alignment. The front right tires is getting some bad inside tire wear but I have not rotated the tires in awhile since I needed new tires.

Here is my plan.

Take out a little slop out in the steering box by adjusting preload with hex bolt on top CCW until no slop is felt while grabbing pitman arm.

Check tie rod slop on each side and replace them if needed.

Check wheel bearing preload by jacking up front of car and grabbing tire at 12 & 6 o'clock and pushing/pulling to see if there is any slop.

Inspected upper control arms on both side. From what I found searching this is probably the reason for the inside tire wear. It would make sense to me that both would need to be replaced so most likely I will replace both.

Is it common to change the upper control arms and not the lower ones? Should I buy the complete control arms or just the bushing kit? I would like to keep the cost down if possible. How does this plan sound?
