- Fuel tank sender - gas guage will not work properly and give erratic readings
- Front end/idler arm - wears out frequently, expensive to fix
- Front brake rotors - require frequent machining and replacement
- Rear brakes (if disks) - expensive to replace
- Parking brake - usually broken, particularily if it's got rear discs and the "easy push" e-brake pedal
- No motor worth getting except a 5.3L with the 4.10's....other motors suck, and the 5.3 doesn't have enough low end to push taller gears.
- Limited slip rear-end is nice, winter traction is marginal without it
- SLT package gets you really nice seats, good stereo, perimeter lighting, and lots of other toys.
Nice truck overall, needs to be bought cheap to be a good deal against newer/brand new alternatives right now. I just sold my 03 SLT and would buy another, for the right price, without great reservation.
