  Love This Truck - 2004 GMC Sierra 2500
  By Brian Eichler - June 19 - 12:10 am

  I have the 2500HD 6.6L Diesel 4x4 Crew Cab SB. This is my third GM 4x4 truck, but first diesel. I tow an RV and put dirt bikes in the back and it drives like I have nothing attached and nothing in the back. I can accelerate going up hills on the freeway fully loaded towing the RV. The interior noise is quieter than my wifes Chevy Blazer. The stereo absolutely rocks, and the seat heaters are so nice - even in San Diego CA! This is the best truck ever made.

  Service 4WD Light - 1999 GMC Sierra 2500
  By cw4915e - March 27 - 5:03 am

  4WD light comes on intermittently lately. Poor troubleshooting procedures from a Chilton manual led me to replace the front diff actuator motor. Seems the real culprit is a sticky selector switch. Humidity may be affecting this switch, apparently the resistors are shot for each position and loses ability to keep voltage signal to transfer case module. Original battery lasted 6 years so that was awesome to get over 6 years from a battery. Also developed a leak at the front differential. First thought it was the output seal but ended up being the plastic vent cap that screws into the diff.

  Great Power with 6.0 liter - 1999 GMC Sierra 2500
  By roy - September 14 - 12:56 am

  ABS electronic module - replaced by dealer in Virgina only problem. Drove 300 miles to pick up - has one of first 6.0 liter engines. Great power. Engine does not show up as option in parts stores until 2001.

  Light Duty GMC 2500 4X4 Crew Cab SLT - 2004 GMC Sierra 2500
  By Ameritruck - January 8 - 9:56 am

  2004 light duty Sierra 2500 4x4 crew cab w/6-1/2 box. A very comfortable, capable hauler of people and cargo. Rear seat area is huge. Seats are very comfortable. Ride is a little choppy unloaded, but that is to be expected. Smoother ride than GMC 2500 Heavy Duty. Tracks down the road very nicely. (This next comment is not a flame, Im a truck guy, not a "brand guy") Much better than Ford 250, which tended to wander a bit - that may have been due to the more aggressive off- road tires on the Ford. With a bed cover in place, gas mileage went from 17.5 mpg highway to just over 18 mpg highway. Every bit helps. XM radio is worth every cent. On-Star is invaluable. Great dealer support during sale.

  A Nice Truck! - 2004 GMC Sierra 2500
  By mark1qhorsey - August 19 - 2:00 am

  Weve driven a 2004 Sierra 2500HD(crew cab)for about 1000 miles. Roomy, excellent fit and finish and performance. I really like the instruments, (XM radio-rocks!) and seat belts. Yes. Its a nice touch to embed the belts into the front seat backs. Gas mileage is average-13.5 mpg here. The instant fuel economy readout helps optimize mpg. We use 88 octaine. GMC convert. Nice Truck!

  Good Truck - 2002 GMC Sierra 2500
  By LM123 - May 30 - 2:00 am

  Overall am pleased with the standard duty 2500. The truck seems to ride and handle much better than the 2500HD if you do not need the extra capacity.

  Great Truck!! - 2002 GMC Sierra 2500
  By John11 - February 21 - 10:00 am

  I have not logged too many miles yet (about 1000), but my first impression is this truck meets high quality standards. I have not found anything that needs tightning, fixing, or changing and I have looked under inside and around this vehicle.
