Wheel bearings and ball joints at 85k. Did the work myself for under $400. My buddy had it done at a shop and just one wheel bearing was $600; they are difficult to change, but if you have the system, they are easy. First one, drivers side bearing and joints took 3 (approx 20 hours) days, passengers side took 7 hours.
Drivers seat has a wobble in it. Easy fix, just haven't done it yet.
Remember to change the cabin air filters yearly.
No major problems.
Fantastic vehicle, I have owned two of them now, a 98 and an 02; the 02 is leaps and bounds better than the 98. The 02 has lots more power, much better gas mileage, and has a better stance when empty or loaded with stuff. Both handled great.
I spend a lot of time in my vehicles, not uncommon to spend 6 or more hours in a day in the truck. The leather seats are very comfortable, the heated seats rock.
Easy to work on, parts are cheap, performance parts are abundant and reasonably priced.
The ride is fantastic; it eats up highway as well as local paved or dirt roads.
4wd is fantastic. I have driven long distances in extremely snowy conditions (I live in the north east) Pulled my buddies international around like a toy, the 4wd low is great.
Easy to change out the stereo except for the stock subwoofer.
I have never had to turn the key more than once, it starts every time and is ready to roar off.
Has a pleasant sound when you punch the accelerator, and puts you in your seat as well as any truck would.
