Just goes to show how many things/systems there are on a vehicle (especially a 4wd one) that you have to pay some attention to now and then (or more often). Not so much that you have to worry about something every time you get behind the wheel, but enough that a semi-regular looking/checking/eyeballing/feeling of the different areas is a good habit to get in to.
They might be modern and reliable vehicles, but they still need some human intervention now and then.
Glad you got it taken care of. Now it'll take care of you better too.
Less stress... Mmm, good.
