Drive Train -- Verified

The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.

The steering may develop a clunk type noise from the upper intermediate steering shaft.  Our technicians tell us that you should check with you local GM dealer to find out what the latest repair is for this condition.

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK.

GMC Sierra 1500 Reviews

no where near the f-150 ford I just sold! This truck is a rust bucket brake and transmission lines all rust! Lots of surface rust! The Ford is a credit to this rust bucket!!!

I used to work at Chevrolet Dealership before I bought a truck i did My home work. I bought a 2006 Sierra because in 2007 the Cast Iron blocks went away and more aluminum started being introduced as well as plastic. However, I did have a major problem with the Clutch some truck that were assembled in Mexico utilzed a master cylinder with a shaft approximately 3/16" too short making it very difficult to Clutch. That one was hard to resolve especiallly because GM and the Dealers wouldn't help. Less is more when it comes to vehicles in my book Less electronics less fancy stuff more time for me and my wallet.

2000 GMC SIERRA 205K and strong

It still looks good and drives good....if you are going in a streight line, with little wind, and even road. Really, its been a great truck, and has power to keep going. The problem is besides the rear main seal leaking a little, it goes through shocks like 8 yrar old boy goes through shoes. It drives straight in perfect conditions, so I guess the entire suspension could be replaced. I am wondering how to get it done reasonably. Telling someone its all worn out usually fires the repair guys dollar sign endorphin so strongly its turns me off to the idea of fixing anything.
I assume the springs are tired, every ball joint and stearing component (minus the rack&pinion unit) have play or are loose, and all the bushings show the 200Kplus miles. I am thinking I should go to maybe a customizing shop where they do lots of suspension work. Ideas, or comments?

I have owned my 2005 for 6 years and have put 134,000 miles on it, it now has 154,000. It has been very reliable. The biggest problems have been headlight bulb replacements, dashboard gauges failing and the damper controls for the driver side is blowing heat all the time.
But overall, it has not left me stranded. 3 sets of tires, 3 set of front brakes. My plan is to drive to at least 200,000 miles.

its a great truck but only one problem! the wires for the headlights on the sierra always get shorts in them and everytime u get going down the road one is out!!!
