I did a search and didn't find anything related to this issue. My boss has an 05 crew cab z71 Silverado. He went home to NY last week a 10 hr drive. On the way home while driving on I-95 doing 75 the trucks front end and steering wheel started to shake violently, he said it was not just a shake but to the point that he thought the wheel was going to come off and the dash was going to fall off the truck. A really violent shake. It lasted for about 10 seconds or so and went away as fast as it happened. This happened about 6 hours into his trip. No other problems the rest of the way to NY. The whole week while he was home nothing but on the way back to NC it happened again 4 hours into his trip. He said it was a serious violent shaking of the steering wheel to the point that it almost put it into a blurr. Nothing on the road, dry sunny day no heavy traffic just normal interstate driving doing 75mph. The truck is at the dealer now to see if they can figure it out. Anyone have any ideas? Not sure the mileage on the truck, maybe 8k miles, not sure it is only a year old. It has me stumped since it just comes on so sudden and then doesn't happen again for a long time.

Most likely he won't believe this, but I would most likely bet that he picked up some sort of debris and it took 10sec. to throw it off. (Which was actually more like 5 sec. because if it were me, theres no way I'd be driving at 70 mph for 10 sec. w/ my truck shaking that bad, probably just seemed like 10)

Ever done any circle track racing? When you get up out of the groove or under caution, you pick up a small chunk of rubber that comes off the tires, it feels like the car is going to fly apart, shaking like you've never felt. Usually it is here and gone w/in a matter of seconds. It's possible he picked up a piece of rubber from a semi or something of that nature.

I agree...when you pick up debris like and arm, or part of a finger caught in the tread...it DOES throw it out of whack! :)

Update on the shaking. The dealer here did a nation wide search on this and said that there has only been two other instances of it happening. It looks to be a bad brake booster/master cylinder. It wasn't really explained to me very well other than if it happend you are suppose to pull up on your brake peddle and see if it stops the shaking. Since it is still under warranty both the master cylinder and booster are getting replaced. Last thing that needs to happen is to have one of the other family members driving the car and it happen and they flip out and loose control of the vehicle.

Thanks for all the replys.

      What have you done to your K2 today?

      By mysery1 · Posted

      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

      5.3 / 6.2 valve covers / oil burning

      By FiLo · Posted

      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

      primary drive belt tensioner

      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.

      10L1000 anyone with High Mileage ? I hate Damocles....

      By Deadwood · Posted

      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.

      6 Speed vs 8 Speed

      By swathdiver · Posted

      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.
