I have a 01/19 Mexico Truck with the AAJF SU4 American Axle GM part# 84605752 one.

Hope this helps.

Will take a picture of mine and compare.

I've got a High Country with 15K and change on the odometer and the SU4 front axle and have not heard a peep.

I've gone under the truck and there is the slop/play where the axle goes into the diff (just like the video in the beginning of this thread) but no noise.

I've been following this thread simply because I don't think that slop should be there and can't be good for the longevity of the drivetrain despite the assurances from GM.

@Matty Patty finally got around to taking the picture. Looks like i have the same part # as yours. The only difference is the last line which i'm thinking is maybe the serial #.

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.

I just checked too and at first thought no play but shook a bit harder and its very small but play is there - in and out - up and down. I have a 19 LT TB Fort Wayne SU4 7/22/19 with 600 miles and absolutely no noise yet. Guess I'll keep watching and hopefully a permanent GM fix in the works for current and future jingle events.

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.

Are these the part that is causing the jingle? Here are my two and so far no noise bu less than 700 miles.

I decided to take a picture of my differential since they’re going to replace it. Once I get a new one I’ll take a picture of that to compare

@pearlymae19 @Thejet07 keep us updated on whether or not the new diffs fix the issue!

Knock on wood- I have been driving mine with the "fix" for 5 days and jingle has NOT returned. Hoping I didn't jinx myself.

My truck goes in on Monday. Don’t know how long it’s going to be there for and unfortunately I may not be doing much driving due to a recent injury. Fingers crossed all goes well and I’ll definitely keep you guys posted. Funny thing happened today. My radio has issues with going black or getting stuck in night mode when it’s daytime(radio replaced and still same issues). Anyway, the touch screen became totally unresponsive. Tried shutting the truck off and restarting. Nothing. After driving for ten minutes or so and pressing the screen a thousand time a screen popped up that said if your a passenger to accept or decline(something to that effect) came up and it suddenly became responsive again. Very strange but not surprising. Sorry for going off topic. Anyone else had this issue?

Similar thing happened to me recently. Screen froze, I tried pressing different buttons and nothing. Then screen went completely black. Shut truck off and then on, nothing. Turned truck off, went to the store, came back 20 minutes later turned on truck and everything started working again like nothing happened. Weird

hi all picked my truck today without the fix because of strike they dont know when a differential will come in i also was told by advisor that my front and rear suspension has all been rebuilt what exactly all that means is my guess?? he said they will beout of options if the differential does not work so i asked if it would then be called a lemon but that was where he stopped his comment was he did not know about lemon laws anyway thats the latest that i have will try and get some pics before they mess with her again will keep you all posted and thanks so much for all the info
