I've notice a popping sound when the truck is cold or has been sitting for several hours but I only notice it when put it on reverse. It sounds like it is coming from the rear end area but I'm not for sure. I was wondering if it could be from the abs brakes or from the drive train?  This is on a 2002 ,2500hd  truck with 2100 miles.

We have had our 2500HD for about 5 weeks and also noticed the noise you described.  It occurs when backing up just after the truck has started to move (maybe about 20 feet).  I wondered if the break calipers where stuck and the noise is caused when they break loose.

Guys

 

Take the truck to your dealer. GM has a TSB for the problem. They have to replace the yoke in the rear end. Covered under warranty

Thanks Man!!!   I have a buddy at work that has the same problem and I'll tell him about it.   :flag:

i had sort of a groan whe backing up which seem to come from the rear suspension but after they turned my diskcs and sanded my calipers the noise is gone. Maybe its the same thing.

well the dealer turned my rear rotors and sanded my pads and said that would fix it. NOT. 1 day later it was back with a veangance. Now it groans even worse than before. Im afraid that if i bring it back they will want to turn the rotor even more and ill be elft with a lot less life in the disc brakes and have to replace them sooner than anticipated.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
