  countryboy34, First off, the 7 pin plug at the back of the truck is standardized. It won't change from truck to truck. Looking into the plug from the back of the truck, the wiring should be as follows: (Also, on my 2003, my stock plastic cover over the jack itself also shows the wiring diagram as well - if you look closely, yours might as well) You should note that in ...

  Well, I got a replacement front differential actuator, and it appears to have solved the problem. The front wheels now engage. I had to splice in the old harness, as the replacement had a different configuration, but otherwise a simple and quick fix.

  I've got an 04' Sierra 4x4. Here's my problem. Sometimes upon starting the truck the lights on the dash for the push button 4-wheel drive will say it's in 4-low. It's not. It also won't switch out of the faulty light by pushing the other 2-hi or 4-hi buttons. Sometimes when it says it's in 4-lo, it will actually drive in the 4-lo gear range but it won't be in 4-wheel ... Read More

  Is the chirp coming from the tires or the suspension components? If it's tires, maybe the tires are getting "air" and chirp when hitting the pavement over those bumps. I don't know. Just offering suggestions. You have zirk fittings on the 1500 other than the steering linkage?

  I have a 2004 GMC Sierra 1500 SLE. I really enjoy my truck but have noticed that the door handles, mirrors, tailgate handle, black trim on rear bumper and the grill have all started to "weather" and look several years older than the rest of the truck. These surfaces are unpainted. Is there any long term cure besides painting these pieces to keep them looking good?
