The Original front lower suspension arms were subsequently replaced with an improved version. The improved ones also included larger ball joints. Rebuilding them is a bear of a job, and costs more than the replacement arms if you pay someone to do it.
I recently replaced my front lowers, uppers, and rear bushings, as well as rebuilt the air shocks, among other things. It now rights like new or better (I replaced the stock dampers with Koni FSD's).
I would suggest the following items on a maintenance basis;
Change front and rear diff oils - now, and every 25-30k thereafter. Monitor for mud or foam due to water contamination.
Change transfer case oil, every 60k miles anyway..
Change Transmission fluid every 60-75k minimum particularly if you are towing, the Lifeguard 6 is only rated for about 75k kilometers regardless of what the dealer says.
Plan on changing the brake light switch in the cabin if it hasn't been done already, early models all eventually fail and cause faults due to arcing in the switch. If you head it off before a problem, you can carry the old one as a spare.
There's a spares write up, page 1 is a cowl inspection write up, page 2 is the spares write up I did with pictures if you're doing some remote treks that might be worth considering.
PM me if you need any additional information or links.
Here's a picture of one type of winch mount bumper.
