Dented Driveshaft?


Recommended Posts

On a scale of 1 to "needs to be replaced", how bad is this?

 

The truck is 9 days old and I finally got a chance to crawl underneath it to get an idea of how hard it's going to be to install a lift. That's when I found it... My wife actually mentioned she felt like it vibrated some, and I sometimes thought that too, but I was hoping it was in my head. Maybe not?

Kill it with fire.

 

 

In all honesty spend a hundred or so and have an independent driveline shop look at it. Dealer will say it was something you did and charge you a lot.

Even on a truck that's 9 days old? lol

This is the replacement truck for the one I bought originally, that had an emissions system failure, random cylinder misfire, and traction control failure, then died on the side of the road (literally the engine shut off with the key still in it) all before I hit 180 miles.

 

Hopefully they will make this right, I've had less issues with all of my other cars combined in the last 10 years than I have had in the last two weeks or so...

Also, what would cause that? Maybe putting it on a lift where the drive shaft drooped and rested on the corner of the platform? Or does GM pick these things up with a forklift to move them around? The driveshaft is obviously lower than the frame, so the forks could dent it?

Coming off the transport at too much angle could do it too...hard to tell if it has abrasion marks?

I would take it back to my dealership and have it replaced. I couldn't imagine a reputable dealer giving you any problems.

Yup.. if the dealer of delivery was responsible for the damage then they have to be the ones to fix it, but more than likely they'll tell you they didn't do it and won't cover warranty.

Its a shame because any dealer should warranty it. Contact GM if they don't help to have it escalated, that should work.

This most likely happened by a unexperienced person putting it on a lift.

I can remember years ago when a kid working a Pace in the tire and battery shop. We had a guy replace four tires on a typical van. We had two types of lifts, one was for cars and others for trucks and vans. They only came about two feet of the ground. When the guy was done with the van he took it around the parking lot for a test drive. I was looking at it at the top of the parking lot driving around and noticed a lump of something would show repetitively from the bottom of the van. Well I noticed right away that he bent the drive shaft and didn't even realize it. When he got back I said to him you just might want to look under the van. He did and said holy shit thats what the banging was. It made a dent in the floor pan as well. Very funny at the time.

Isn't that just a cover? I was under mine today and noticed it. Looked like a shield for the actual drives after.

No. The driveshafts are hollow aluminum. And the shock mount on your axle in normal, not bent.

    • I have a 2018 Silverado Custom with 156k on the odometer. In the last month I've replaced the plugs, wires and the driver side engine mount. My wife just returned from a trip of about 1500 miles and told me the brakes are making a grinding noise when applied. I drove it and looked it over and this is what I found with the driver's side rear rotor.   I'm going to order new pads and check about having the rotor resurfaced. Hopefully this is easier than the last 2 jobs.   Peace  
    • Any update if the new valve cover help with the oil consumption?  I have a 2014 GMC sierra and my truck is consuming a lot of oil so I’m wondering if replacing the driver side valve cover will stop some of the oil consumption. Thanks 
    • I bought belts and pulleys for my '20 L5P at Rock Auto a couple years ago. I have used them for many years, and almost always save significant money, especially when I buy maintenance stuff ahead of time.   They carry many OEM parts, which is all I use unless an aftermarket is shown to be same/superior, or if it is an insignificant part or unavailable OEM part anywhere else. RA is usually lower priced, often by a bunch, but parts are sometimes unavailable or out of stock, and I do shop around and sometimes find better prices at other sites.   Be aware that you pay shipping, and if you buy multiple items and they are coming from different warehouses, the shipping can kill the advantage. Planning ahead is best if possible.   If you have a transmission service in the near future, check out their OEM (AC Delco ULV) fluid, usually MUCH less than anywhere else.
    • New member here, very long time occasional guest. Saw this thread, thought it would be a good time to contribute someting. It is only my experience and not a claim that everyone will have the same.   I bought my '20 3500 L5P new and have put 99.9% (literally) of it's current ~400k miles on it myself, with over 50% of that towing loads between 4k to 15k, and to me this truck has been nothing short of amazing. For the first 235k I had zero issues, and from there until 321k I replaced a NOx sensor, two failing glow plugs, and three of the notorious injector connectors. I believe this truck is in part, a testament to good luck, but also good care and following a decent maintenance schedule (I also keep meticulous records.) As a result, it looks as good as a well cared for 70k rig, up and down, inside and out.   At some point before that 321k mile mark I began to get a little spooked about the 10L1000, especially the valve body. Word of mouth about potential issues prompted me to jump on the net to sift through all the noise and determine what all the fuss was about. I routinely take long trips, coast-to-coast and points in between, so roadside breakdowns can be '...a thousand miles from nowhere' and a bit of a challenge, and though I had no issues, my guard was up and activated.   And then I stumbled across a chance to salvage some parts off a new 2025 that had been wrecked in transport. I grabbed a few wear items (alternator, pulleys, etc.) and on a whim asked what the ten speeder would cost me. It was cheap...really cheap. I knew some changes had been made in the '24+ version 10L and were supposedly not compatible, but I called service/parts at my local Chevy dealer and asked why and they didn't know. A call to a well known aftermarket transmission outfit revealed it was very likely it would be fine, but to them not 100% sure.   Because it was cheap (really cheap) and I was spooked, I took the chance. Had it installed by a local shop and it worked like a champ, shifted just like the original. At it's first service at 37k, I had the shop put in a Next Gen valve body kit, which after some initial hiccups and rough shifts, smoothed out though with somewhat firmer shifting.   All that said, I have a very serious concern about my newer transmission as just two weeks ago it suddenly began to exhibit a strong reluctance to engage forward or reverse. It was a bit past due anyway so I took it in for service. The reason it was sticking was due to 'glitter' in the fluid clogging the filter...not good folks, often indicates a converter giving out. We ended up going ahead with the new filter and fluid, first to see if it would move and shift, and then if so buy me a little time. It did, and I've driven it over a thousand miles and it is shifting smooth, no noises or slipping. Regardless, it looks like a third gearbox is in my future so I can resume taking long trips with some confidence. In the very short term, my curiosity will have me examining the fluid to check how much glitter has reappeared.   An earlier poster had alleged, in the context of 10L100 failures, that it is another example of how we seasoned citizens somehow descend into hysteria, lose control of our senses, and react irrationally after brief encounters with the idiocy of the internet infosphere. Let me say (and I have used and abused said internet since it's infancy) there is no segment of the populace that has a corner on over-reaction to digital garbage. Just as my offering of experience in this arena is purely anecdotal and should not be considered gospel or all-encompassing, I believe it is still worthwhile information to consider, along with other relevant anecdotal experiences about things like complex transmissions, especially when balanced with other sources.   So to answer the original question, yes I got high miles out of my first 10L, trouble free for 321,000. Now I really wonder how much longer it would have went. Did I 'overreact' to the internet ghouls by replacing a 'good' one with a 'bad' one? Maybe. Who knows, the thing might have taken a puke a 100 miles later. So I'll just fix it again, then move on and start thinking about all the other stuff that will eventually wear out. It still has the original brakes (they're at ~60%), original injectors/pump, turbo, water pump, etc....pretty much original everything. Knock on wood.
    • At peak temperature.  They get to cool down and warm up more, especially those with the external cooler.  I have three GMT900s and one of them has over 225K on its original transmission.  Fluid gets changed about every 36K miles, all of it.     It's not the bean counters, it was the government.  They had to meet CAFE standards and other government requirements.   To get around that, we tune them and modify them to our liking.
