  1. My build date is 11/18 so I must have the old fluid. Is GM replacing the fluid to the new stuff free of charge/warranty or TSB?
  2. Other alternative is buying the all steel leaf springs online. They are only $148 each.
  3. It is an AAM axle. The AAKG sticker being in that location on the axle is the tell-tale. If it were a GM axle, the sticker is on top of the axle not on the bottom. The 2”x2” “GM” symbol is also cast into the axle housing on the rear left side of GM axles.
  4. Yup definitely a new axle. Mine is an AAHD and I’ve seen AAJF. The GM axles I’ve seen were AAJ8. AAKG seems to be the newest iteration and hopefully has all the issues fixed.
  5. I almost went LTZ but I found I could get a fully loaded LT 5.3L Z71 much cheaper. It has the Leather seat upgrade and also the safety package 1 which includes blind spot monitoring and front and rear parking sensors with cross traffic alert. Task lighting came with the package as well as the spray in bed liner and rear power window. I also like the amount of chrome on the LT, there is a little too much on the LTZ in my opinion. The only things my LT doesn’t have are cooled seats, lane keep assist, 360 deg camera view, Bose sound, and wireless charging pad. It doesn’t have factory navigation but since I have the IOS radio I can upgrade it later for about $500. These options on an LTZ would have cost thousands more. The MSRP on my LT was $53K. Got it for $41K during the April truck month with all the incentives that were offered at the time. Being it’s the year end of the 2019 models, you could probably get a similar deal.
  6. Depending on how much you need to get out of it, you’ll have better luck with certain websites. Last year I sold our 2015 Traverse to Carvana. They offered a good price on it and they come to you to pick it up. They handled the paperwork and payoff right there on the spot and cut you a check for the balance.
  7. If you don’t want to encounter issues with speedometer being too far off calibration or have any issues with running or clearance then stick with a 30 to 33” tire. If your stock wheels are 20”, you already have a 33” tire (275/60/20). Going any taller or wider in tire size you may have to add spacers, a suspension lift, or modify the mud flap brackets.
  8. Per my past posts from pages ago, I’ve checked about 10 other trucks on the dealer lot, LTZ, LT, RST, TB and they all had the same small amount of play. Even the SU5 GM axles had the same amount of play and they are not even affected. I’m thinking about going to crawl under a few Rams, F-150s, Tundra on the lot and see what their CV shafts are like.
  9. Same as you except I’m only at 4100 miles. The CV shaft play is present at the axle but I have no noise either. The amount of play is small but I agree, I don’t think it should be there either. For the people having the noise problem, it does go away when 4WD is activated. So I wonder if the play exists when the shafts are engaged.
  10. 4,000 miles on my SU4. No issues so far. Model AAHD with part number 84557635. My truck was made late November 2018.
  11. This issue relates to the front axle. What is your RPO for the front? SU4 or SU5. SU4 is the one that is affected.
  12. SinCityTrailBoss has been active in this topic and has a trail boss with the issue. I want to say there was also a few others but don’t want to search the last 40 pages for them.
  13. It makes too much sense for them to send the SU5 axle so it probably won’t be that one. I’m pretty sure GM will only replace an SU4 with another SU4 so the RPO codes don’t get mixed up for your VIN. Manufacturing has become very lean and efficient over the years but unfortunately has also become pretty stubborn and stupid because of it.
  14. Me too. Though I’m thinking I may never get an answer. The only trucks in the lineup that use the composite springs springs are the 5.3L LT and the Sierra Denali.
