  1. Fixed rough idle

    Greystone, would you mind grabbing your invoice for this visit and sharing with us any information that pertains to getting the ECM updated for a batter idle? I'd rather my dealer start with doing something like this before we throw motor mounts and other stuff at it. My truck has 10k miles and runs smooth in rhythm but rough in feeling. Your help is greatly appreciated!
  2. Backlash? Guys, your gears aren't going to cause the shaking/vibration type that we're experiencing. Humming and whining are more indicative of a backlash issue. This shaking we're all experiencing is related to a rotating mass (axles, tires, wheels, brake rotors, driveshaft, etc). Even pinion angle would have more of an effect than backlash.
  3. Yes they are extremely rare. Probably the rarest of the body configurations. Then to find one with a power seat and fog lights is even tougher. Are you looking to buy new only? I have a 2017 that I would consider selling that has 7800 miles on it. Black in color. I am in MN though. It got stored last winter. I haven't driven it much but have been considering buying a sports car instead. PM me if interested.
  4. My 2015 Silverado was so bad I went through 4 rear differentials before I had one that worked (didn't whine) in less than 2300 miles. (no that's not a typo).
  5. Wow, the rear differential is that bad in the 14-18 trucks that they only used it for 4 years before redesigning it again. Hopefully this will solve all the manufacturing issues they had with the previous ones.
  6. The last time I tightened up the backlash on a rear differential, it went out about 20k miles later. Once the gears have taken set, I would advise not changing backlash or making any other adjustments. Maybe you'll get lucky, I guess I would advise just be careful.
  7. 2019 Silverado Priced Starting At $29,795

    Wow, is the regular cab short box truck dead? I bet the extended cab short box truck shares the same frame as the regular cab long box. Is this the death of this body configuration?
  8. Crack in paint

    Check for accidents. It could be bondo cracking under the paint.
  9. My new 2018, SLE Regular Cab

    If I didn't know any better, I'd think I was looking at my truck. Indeed the black reg cab, short box GMC SLE trucks are hard to find. Especially the ones with the power convenience package (power seats, fog lights, etc). I live in MN and drove to Boise, ID to get mine from Dennis Dillon. Everything was going well until I got there though and they changed the price on me. That's a whole different story though. It's hard to beat the looks on these. Probably the best looking GM fullsize truck on the road. I also agree, I think the 3.42 trucks with the 5.3L in this body configuration are the fastest combo out there.
  10. I don't know how much more premium is in your area vs 87 but in MN it's only 20 cents more a gallon. 20 cents times 20 gallons (at fillup) equates to 4 dollars. I would just spend the $4 at each fillup and be done. I run 91 non-oxy in all my stuff since I don't like ethanol touching the fuel components of my vehicles.
  11. How long would you say they needed your truck in the shop to replace the mounts? Is this something you can wait for or does it take more than a couple hours?
  12. I see they still haven't fixed the issue with the uneven tailgate cables. One is taught and the other has slack in it.
  13. Still waiting for those part numbers on the updated mounts.......
  14. I still contend it has to do with an unbalance of the firing of the engine. Not the firing order but at a low speed there's cylinder pressure being bled off, weak spark or an imbalance of fuel making its way into all 8 cyls. Is it fuel? Valves not seating? Rings? something related to AFM? The lower the engine speed, the more sensitive an engine is to any flaws in operation. The first test would be a leakdown and compression test of all 8 cyls. If those were good I would flowmatch the injectors. If that's all fine then I'd be looking at spark. Maybe it has something even to do with the cam lobes on 4 of the cyls being different than the other 4 (AFM camshafts aren't symmetrical)
  15. I plan on doing mine in the driveway. My local dealer I wouldn't trust with an air filter change so that's why I'm just going to do these myself. I plan on pulling the fender liners then loosening up trans mount, both motor mounts and I haven't decided if I should remove manifolds or loosen up the y-pipe. I'll probably do manifolds since I don't have a hoist but that's no big deal. Where would you suggest jacking the engine up by? My truck is 2wd. I'd love to see a video if you made one!
