Here's a picture of the factory rear stabilizer bar end links Mopar PN # 68361275AC. Your's are defiantly aftermarket and were not put on correctly. My guess is someone forgot to tighten the top nuts and they eventually fell off.

The pullies can be replaced but you would need to find a place that rebuilds starters and alternators (there aren't many around anymore) plus remove the alternator and put it back on yourself.
The 0w (w is for winter) weight is for moving oil quickly through the engine during winter startups in below freezing temps not for fuel economy.
The 20 weight is where is the oil is normally at during operating temperature of 100 degrees (oil temp) or more.

You can also call the tire manufacturers customer service and they should be able to tell you what, for your specific tire, the minimum tire pressure is for your vehicles fully loaded weight. I have done this before and it will give you a starting point.

Lights acting strang especially the shifter lights means one or both of your batties are almost dead. Guy on the way-a-life YouTube channel had the same issue with his JL, see the video posted about replacing batties.
Drive them until they are dripping fluid or have no pressure left in one or more shocks (my guess would be 50k-100k miles). Then rebuild or replace them whichever is more cost effective. These are not dedicated racing shocks that need to be rebuilt after every race, these are OEM shocks that...
From the 2021 JT owners manual page 484. The engine is controlled by a computer which is programmed and optimized to work with 87 octane. There is no benefit with higher octane like there was back in the day with carbureted engines.

Mopar sells upgraded gears any dealer that says it voids your drivetrain warranty doesn't know what they're talking about:
4.10's factory gears same as a 3.6 Rubicon
