I am in charge of doing basic repairs on a U.S Government passenger van and was hoping some questions could be answered.

How do you change the door locks so they do not lock-up as soon as you put it in drive?

The passenger side front lug nuts always work themselves loose before the others, but I always catch them when they are still pretty tight. Just normal behaviour or something else?

The tire pressure system is on the fritz, I see no need to fix it, and my supervisor agrees with me. As long as the tires are good is there anything I need to be worried about?
