    2003 GMC Sierra 1500
  1. 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).
  2. 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).
  3. 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.
  4. 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.
  5. 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.
  6. Four wheel drive problems?

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

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

    Gotta do mine too. Thanks for the info!
  10. I think its more right in the center at the back of the motor. Indeed difficult to get to. I had someone else install mine.
  11. Depending on where you live or where the truck is from, rusting brake and fuel lines are something to look out for. My e brake system is totally gone as well.
  12. Replacing fuel lines

    I paid about $200 for a replacement set from Lines To Go. Was going to do myself but heard its difficult to get the bracket off the top of the bell-housing. I'm also not sure if I can get the pre-bent lines around the ABS module and torsion tube crossmember (don't want to have to take those lose). It can also be difficult to get the connections at the fuel tank apart if they're really rusty (like mine). I'll be getting a quote for a mechanic to do soon.
  13. Transfer case info

    You can get those RPO codes from the label on the inside of the glove box.
  14. Transfer case info

    What is your RPO code? That should narrow it down. It might be stamped/labeled on the case as well.
  15. Rear Diff

    When I did mine, I found that when I pounded the 6 point socket on them to get them off, they "cleaned up" fairly well and I ended up reusing them without any issues. You are replacing that cover right? What else you planning on doing?
