I appreciate your response here- very informative. I actually ended up passing on the Silverado as I was just too worried about this issue , and still have a bit of a sour taste left from my lemon 2017 ltz. Ended up trying a Chrysler product and picked up a Jeep trackhawk. I wish all the best to the T1 owners , beautiful trucks for sure.

Thanks for the reply, great to know and good points. I will see if I can identify the part numbers when I see it again next week.

Thanks for your reply. My concern is taking delivery of a brand new truck that has a manufacture defected front axle that up to today- no one has currently confirmed a repair for it. Reading this thread and hearing people expressing how terrible the problem is and how gm still hasn’t been able to fix it is what’s scary. My dealer said they can’t swap it for the gm su5. It’s disspaointing that gm would sell another brand new truck that comes with a faulty part- obviously being new it will have the warranty but the last thing I want is another truck that I will have to spend considerable time at the service center for them to again try fix something they don’t have a proper fix for. I essentially don’t want to get into another lemon, that is my concern- this current ‘17 I have has been terrible. It’s really a shame because I custom specd and ordered this new T1, it just arrived and is/drives so nice, but if at a couple hundred miles the axle will start jingling since it already moves back and forth with my hand test now, and I’ll have to take it in to service with no confirmed mend, then I mise well unfortunately pass on it. If there are any people who have the su4 axle that has movement under the hand test but haven’t experienced any jingle after some miles I would be interested to hear, I just wonder if all are affected or only a portion of the su4’s.

Thank you for the reply and suggestion.

Hello- Chiming in on this thread after reading the last 30+ pages as I would like your guys Input.. I have a 2017 6.2 8 speed z71 ltz that I am currently in the process of lemon lawing due to the dreaded 8 speed drivetrain clunk , and it should be completed next week (a long and strenuous 4 month process). I recently ordered a ‘19 ltz 6.2 10 speed 4x4 to replace my ‘17 and it just arrived to the dealer (build date 7/22/19) - I had the dealer look up the axle and it unfortunately has the su4, I got under it to test it and the axle moves back and forth as the previous posts and videos describe. It’s brand new, drives perfect and is beautiful however this thread has me terrified to move forward with the purchase, as I do not want another lemon. I spoke with the sales manager and he mentioned that there is no way they can specifiy to request the gm su5 axle when ordering as it’s not part of a package and just basically up to chance as to what axle you get. So my question is- should I take delivery and hope for the best, re order and hope for the best, or look elsewhere ?
