    2003 GMC Sierra 1500
  1. Fuel line leak

    It was like 4 or 5 months before it started leaking in some other spot and so did total replace.
  2. Fuel line leak

    Did mine with rubber hose and clamps until I was able to replace all the lines (which was a pain).
  3. Did you get this info yet? Will check mine tonight if you have not.
  4. Transfer case is in 2HI. Front wheels are not turning. Noise sounds like coming from transfer case. Was hoping someone might have dealt with this before.
  5. Fighting a vibration

    Great info. My shocks are worn too. The CV reasoning sounds very plausible.
  6. OK Here's my sound. Truck is up on jack stands and I'm turning the rear wheels. Camera is under transfer case. Squeaks like this when leaving standing start and eventually stops when going fast enough (20 mph). Fluid in transfer case is fresh. Thoughts?
  7. Fighting a vibration

    I've had a similar problem just as you describe, but it comes and goes. When at 65, it goes away when I let off the gas and changes if the truck is "bouncing" from say a dip in the road. Seems like mine comes from the front end. I'm thinking U joints or differential. Haven't had the chance to really look at either.
  8. Mystery Part

    On my 2003 the rears are mounted to a plate which then bolts onto the axle. I think the fronts just slip on (no plate).
  9. Mystery Part

    Bumper for either the rear springs (mounted to axle) or the front control arms. Probably the front. The rears are a little longer (taller).
  10. Do they have the same spline count on the back end? While doing some research on transfer cases for my 03, I found out it has 27 on the input (Transfer case). I believe older ones had more (like 32). Not sure about the other differences you note.
  11. John, Permatex makes a hydraulic sealant that cures in the threads and can handle up to 10,000psi. Its in a 36ml bottle which will be more than you will probably ever need. Item number 54540. Since you are using stainless steel, you would also want to use the Surface Prep item 24163 to help it cure.
  12. 03 1500 with plow mounts

    Look for rusted fuel and brake lines. My transfer case (and differential pan) corroded to the point of leaking as well. Broken exhaust manifold bolts, fresh fluids, smooth shifting.
  13. Four wheel drive problems?

    Maybe bad encoder/motor. Its not positioning the gears in the right spot.
  14. Airbag light random

    Where was the bad contact?
  15. All the Tech2s I see on eBay state they are not for trucks. Anyone have a better source?
