Like with the actuator, this forum was great, a little research into what others have done, and the most likely diagnosis, and then the link to the parts supplier showed a picture of what the actuator looks like. I could see where the actuator was screwed in on the differential. The actuator is mechanical, operated through an electrical connection. The only little issue with mine was that the electrical connector wasn't compatible, and I had to splice the old one onto the new part. It's always bit of a chance, just buying a new part, when it could be switches or something else, but the actuator reportedly fails after a period of time, and I knew the low range switches, lights and gears worked. Simple things first. And I guess I was lucky.

Replying to: jbeyhi (May 15, 2009 7:51 pm) That's why GM is going bankrupt. They rarely if ever concern themselves with a design fix or a manufacturing defect during a model run.....i.e. 1999 to 2007. The internet is full of the same usually expensive electrical / electronic problems that GM knew about since the late 1999 model that existed on this switch and transfer case motor and also a cable connector as well as many other similar problems (heater actuator, etc).   I have a 2000 GMC Sierra with very low mileage which just today started the same 4wd symptoms as yours.   If GM would have attempted to make every vehicle model continually better each model year they would have ended up with super reliability and quality and they could have Americans lining up to buy their products. Instead they continued to do the same thing they've done for 50 years and never make product adjustments or improvements during the 5 or more years of a model run. The customers are forced to deal with the expense and and inconvenience and poor resale.   The CEO (Wagner, etc) only worried about his jets, bonuses and bennies, not making the best car. Sorry for the rant but every time I think about tax payers bailing them out it ticks me off but not as much as when I think of their incompetent executive management and lack of priorities .
#183 of 233 2000 Silverado 1500 4x4 what's wrong? by krazyk22 Jun 23, 2009 (2:28 pm)
I own a 2000 Silverado 1500 4x4 with 125K miles. Here recently when I accelerate, the truck often revs up into the 3000 rpms, and and sounds like it's going, but the truck doesn't move. I have been assuming it must be the transmission, but could this be something else? Replies to this message: obyone (Jun 23, 2009 11:36 pm)

Replying to: krazyk22 (Jun 23, 2009 2:28 pm) You're correct. It's the transmission.

since it has no torsion bars, is there any way to level front end without lift? Replies to this message: havatoker (Jul 26, 2009 5:22 pm)

Replying to: ognend (Mar 31, 2009 3:02 pm) Hey there Ognen, First of all, to shift into/out of 4Lo you have to be stopped and put the transmission in neutral. And I would recommend to back up several feet after you shift out of 4Lo if you are able to to ensure that the front end is completely disengaged. When ever you are in 4X4 mode and you are have the wheel cranked all the way right or left, your front end will feel like it is binding or "skipping" if you prefer, which is perfectly normal. It will not feel like a 2wd because it a 2wd has no drive line up front.
#187 of 233 trouble with front seal and noise by longtimegmfan Jul 25, 2009 (12:01 pm)
I recently replaced a front seal on my 2002 Silverado. When I went to a parts dealer to buy it, he said he had 60 in stock due to the number he had to sell for replacement. Now it makes some nice extra noise. Anyone else having the same problem?
