It's been discussed here some in the past, but worth repeating for the benefit of new members - the suspension and steering parts on our later trucks lack grease fittings, relying instead on "superior" design and materials for normal lifespan...
Yeah, SUUuuuuure!
What I do on my '02, is use a hypodermic needle greasegun attachment available at most auto parts stores to carefully penetrate the rubber jackets on the various pivot points where there USED to be grease fittings, and then CAREFULLY pump in just enough grease to visibly "plump up" the sealed boot. Too much grease may rupture that boot and do more harm than good, so care is advised.
Some small amount of grease will probably slowly leak back out the penetration point, and is normal - I like to redo mine about once every year - but it depends on owner use - heavy use under heavy loads, off-road or construction use may benefit from more frequent lube. It's a good idea the remember the sliding shaft at the driveshaft center support as well as the rest of the usual points...
My old '91 that DID have greasable suspension, had 120,000 miles and 11 busy years on it when I sold it, with all OEM steering and suspension parts still in perfect operating condition - hope to get the same from the '02...
