    had the problem with my cable, I just cleaned it real good and put a copper between the two cables with some good lub so it would stop getting corroded no problem in two years.

    now I have a new problem with my 96 Sierra, any ideas before I have it towed.

    the starter turns over fine, no run
    the fuel pump runs. getting fuel on the rail.
    pulled #1 done comp test 150lbs. put the plug on the #1 wire
    it's firing.
    put some gas in the intake still no run
    pulled the cap and rotor button looks good

    tell me something good thanks

    The 2003's were to get an updated shaft. This never happened and the fix is listed as grease it and good to go for another 10k or so. I guess GM has other more pressing problems as this intermediate shaft issue started in '99 and continues today in '06. How's that for product consistency?

    I have a '02 Denali which had the problem. The fix? I lowered the front end 1" and no more slack in the steering shaft.
  • Thanks for the info. I saw a link on a website, maybe this one, to GMDIESELTECH.COM. He sells a grease kit for the shaft for $15. I think that I will give that a try before I go a lower my front end. Too much snow where I am from to do that. I will let you know how it works... Thanks again
  • I just purchased a 2006 gmc sierra crew cab 2wd, and it has a terrible shake or bounce at 40mph and beyond. Smooths out slightly at higher speeds. Bought truck brand new and have already replaced tires with michelins as I always do. Has any else ran into this problem?

    I have a 2006 crew as well that has had a long history of vibration. Mine started at 70 to 75 mph. My dealer has replaced tires, rear shocks, all brake drums, rotors, pads, and shoes. Nothing worked. Finally, I discovered that if I used the parking brake periodically, the vibration went away. Mine was in the rear brakes. There is a technical bulletin dated June 06 that has a replacement for the rear brake adjusters that fixes a problem with the rear brakes over tightening themselves. This causes them to rub ever so slightly and in my case caused the vibration. By using the parking brake, I was re adjusting them to the proper clearance. :)
  • I have a 2004 GMC Sierra *2WD, 5.3Liter V8. I want to change out all interior lighting from OEM to LED Lighting.

    The Map Lights are #578 Bulbs and I am haing problems finding a cross reference for this OEM Bulb Number as well as how to remove these bulbs from their housing. I can easily remove the Light's Clear Plastic Cover and from there I am stuck physically removing the bulb?

    Can anyone help me out???
  • I have a 2003 2500hd sierra with 6.0L. Recently the battery light is dimmly lit with the key out or with the key on. Also, while driving the light will go brite and "battery not charging" will come into the display and will only last 5 to 10 seconds at the most. The battery died a few weeks ago and it was replaced. Ihave replaced the alternator (twice). Once at the advice of GMC, he said one of the diodes were bad. The alternator is charging 14 volts all the time even when problem shows up. It seems to show up during accelerations and large gas pedal travel but I am still trying to confirm that.
    Anyone have any ideas?

    Where did you get the replacement alternator from? Was it a genuine GM alternator, or one of those Auto Zone of Advance Auto parts specials? If latter, that could be your problem. The alternator needs to put out correct number of amps at the correct voltage to function properly. Proper voltage alone does not guarantee a properly functioning alternator.
