Well finally got the truck back after it being in the shop again for 5 days. This is already after their last final repair attempt, with the new half shaft, fixed it for 350 miles before the jingle returned.

This fix did not work for me. 40 miles after pickup, the noise is back and louder. Each time they take the axle out it gets worse.

I am praying they will buy it back next week. Not sure how much longer I can deal with the noise.

I have the SU4 and I can hear the noise a little bit but it’s not enough to bother me. The 6.2 engine makes enough noises that it all blends nicely like an orchestra of testosterone and tornados.

Just curious - I'm having my first attempt at repair tomorrow - has anyone had the fix actually work? It seems like most people got it fixed and it didn't work.

How long did it take for the dealership to get the repair kit in? I called my dealership last Friday to have them order it.

It took several months. I tried to get it fixed back in May but was told they couldn't get the parts for a few months. They finally got the parts in yesterday

I just got word that my parts came in today and I am scheduled for the repair on the 9/29. It was about 2 weeks from ordering to the call today. I will say I don’t know if my call to Chevy customer support made any difference in the part delivery timing. The rep said they were expediting. Will report back after Tuesday how it goes.

So I just read over the updated PIP5653G and I am shocked at how they are attempting to fixing this. 

They are putting a O-RING on the stub shaft first and then a retainer ring. They essentially want the O-RING to push up on the retainer ring so it will be forced into the diff housings notch to prevent lateral movement of the stub shaft...

Am I crazy or does this sound absolutely retarded?

It doesn’t inspire confidence but it’s the first thing they have done since just keep replacing the axle with another one that is prone to the problem. I was told they changed the axle. I tried to get a part revision history from a few part suppliers but they weren’t able to tell me anything. So if this is coupled with a change in the stub shaft and is just an insurance policy.. maybe not so crazy. If it’s just this and nothing else.. yeah it’s crazy and why I am nervous this doesn’t fix it. Some have said it doesn’t in this thread and some have said it did work but for how long is the unknown.

 

I just can’t believe they screwed this up so bad and can’t fix it. Its not like this is the first 4wd system they ever built. And only seems to be from one supplier so it should be easy from a quality perspective to figure out what the hell is going on. Get one of the good ones and one of the many buy backs and play the “what’s different game”.

Im really hoping they come up with a better solution than a .02 o ring that will need to be replaced over time... Good things its a PIP and not a TSB at this point... I am really hoping...

That little o ring has now failed on me two times. Give it a few hundred miles. Drive the truck for at minimum 45 to 60 min. It will come back

This is just to get you thru the warranty after which the say, change the oring for 750.00. 

It is a geometry issue where the stub shaft falls to the low point. The oring is just a temp cushion until it fails. Get an extended warranty or learn to replace yourself or just turn up the Bose

The stub shaft isnt "falling" to a low point, its moving laterally causing it to hit the center pin. The o ring is keeping the "clip" expanded so nothing moves... If anything, im going to buy the SU5 axle and just replace it myself.

I figured this and had not intention of believing it would work in the first place.

Buy what you want, it’s a design flaw. I agree it moving laterally, but to the low point which is the pumpkin. it’s called gravity. If they new a simple fix like replacing an axle, they would have done fixed it.

I looked at mine with the diff cover off, it was flush with the center pin

    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?   
    • Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
