  1. The horrible vibration on my 15 CC was corrected by installing new Yukon Axles (rear) and rear rotors and pads. The driveshaft was balanced, but did not make a huge improvement. Check out the lack of mating between the axle and rotor. That will show just how bad the flange is off. The vibration was crazy betwwen 70-80 and could not go above that speed. I knew it helped as soon as I replaced them, now I just hear tire noise. The entire resonance of the truck changed.

    Things GM should have designed better.
  3. New Yukon Axles (rear) and Raybestos rotors completely fixed my 15 crew cab.
  4. FL335i, Thank you for your post!! The part#s and wrong PN# warning were a big help. I installed new Yukon axles, wheel studs, brake rotors and pads. It made a significant improvement to the point that I don't dread taking this on a 1400 mile trip. I can now hear the tire to road contact over the low resonance and vibration the truck had on the highway. I have attached images of the axle and rotor mating surfaces. Notice some of them on have 50% at best contact and that's just on one side of the bolt circle. I imagine there would be an improvement in just pulling the rotor off and rotating it 180 degrees and reinstalling. The wheels were torqued to 125ft lbs, so it should have complete mating around each lug.
  5. Thanks for the updates on this never ending vibration saga. What is the part# breakdown and prices/vendors? It would be great to track how many of the truck vibration issues are resolved with these parts being replaced. I'm ready to make some purchases, just wanting to make sure the numbers are correct. Thanks!!
  6. I bought 5 gallons of this and covered the entire underside of my 15. http://www.cosmolinedirect.com/cosmoline-rust-veto-342-industrial-grade/ I used the wax undercoating, cheap harbor freight gun and a hot plate to help get the stuff thin enough to spray. Don't get it too hot or it will release the wax that is on the truck. It's going on it's second winter with no issues or factory wax coming loose. I used a 20x30 tarp in my driveway and put the truck up on 6 ton stands with the wheels and wheel-well liners removed. Power wash the truck underneath first, let dry overnight and then start coating it. IT STINKS!! for about a week, but then the frame has a nice thick somewhat rigid coating that will melt and flow into all the crevasses. I only used a gallon and a half so there is plenty left over for future treating.
  7. Check the ground at the front upper left of the dash, under the defrost cover. It is painted and then the wires are secured. If I ever have my defrost cover off, I taking the ground terminal down to bare metal and securing the wires again. There is also a known issue where one of the harnesses is pinched and wires cut open on the side of the instrument panel. It made the electrical system go crazy.
  8. The low voltage reading is a designed. GM put a regulating system on the alernator that keeps voltage at the battery where it should be. All these years, batteries have been overcharged. 12V vs 14.5 or whatever the average alternator puts out. Just so it stays between the high and low bar on the dash. Mine vibrated like crazy at 70 until the dealer replaced the rear ring gear and two rear shocks. A very good rfb on new michelin tires has removed the vibrations at highway speeds. I do plan on getting a custom high speed balanced drive shaft. There is a history of issues with them. GM is not the only mfg that is dealing with out of balance shafts right now. Sorry you are having problems with your truck.
  9. I think the dealer filled it out in my name, using a made up email address. They get $$$ for happy customers at time of sale.
  10. What is the correct Dexron VI gallon jug part number? There seems to be so many versions of this trans fluid. I want to make sure I'm getting the latest. This will be for the six speed trans. 2015 Silverado CC 5.3 4wd. Thank you.
  11. File a complaint with NTSB if yours has the issue!! I think the only time GM listens to customers is when the government has to step in and force them to correct issues.
  12. What is the part#? That should indicate the color. Does this have the pro check valve upgrade? When would you be able to ship this if I purchase? It's not the best timing for a seller, but UPR has these at $349 for March. That's why I was asking about the price. Thanks, Mike
  13. For the parts you are looking to replace, I would go to the dealer and ask to get the best price for all. If you order a fender or bumper online and it's damaged you will be weeks behind in your repair and still may not get a good one the second time... or third. I am looking to replace all the springs on my 15 with ones from a 17. The local dealer is within $50 of major internet GM parts houses. So in this case, the local dealer ends up making at a sale a better price than the online guys. This is not always true for all parts though and sometimes the local dealer is twice what the online have a part for.
  14. Hi Joe, What is the total shipped price of 1qty 5030-168-1-CSS Full system - Black Finish to 40356? Does it come with check valves and the upgraded ones are $69 or does it not have any to begin with? Thanks, Mike
