My truck doesn't let you select 4wd without prompting you to go into neutral on the screen. Yes, I meant to post here because of my shake at ~40-50mph. Put it in 4lo to crawl out of a mudhole in the driveway. Thanks for the info!

This will probably be my last post here. Here's the end of my story. Dealer two couldn't get GM to do anything but gave me the name of a local shop that specializes in suspension and "lifts". (Boi

Before adding the spring clamps, check the torque or your U-bolts. I suspect that many of them were either not tightened properly from the factory or they have came loose over time due to loctite not

Maybe the answer at last....   After a typical dealer visit I decided to try one last thing before replacing the Magneride shocks. First some history; I had the exact same truck in a 2014 that di

Yeah 4hi would be sufficient honestly for future use, most people will never need 4low in their life honestly

Sorry, id understood that 4lo is for crawling and slow action, hi is for hiway use. Maybe I read wrong...

 

From the owners manual:

 

(Four-Wheel Drive Low):

This setting also engages the front axle and delivers extra torque. Choose if driving off-road in deep sand, deep mud, or deep snow, and while climbing or descending steep hills. When engaged, keep vehicle speed below 72 km/h (45 mph).

 

note the "and". Even in these situations you probably won't need it.

 

 

Edit: Use Auto for Highway, 4Hi for off-road / extreme conditions, 4Lo when you need more torque in 4Hi conditions (rarely if ever).

 

 

Your issue is probably a little separate but would be nice to see your vibration now in a video; If its a similar vibration we can probably narrow the shake to the front end like I've suspected for a while now.

I had my driveshaft trued and no more shaking!

 

RT

Before you had your driveshaft balanced and trued, did you ever put your truck in neutral to see if the vibrations/shakes quit? On my previous truck, 2000 Silverado z71, the driveshaft was so out of balance and u joints were so worn, whenever I put it in neutral going down the road, the vibrations immediately stopped.

Get your driveshaft checked by a specialist. I have no more 75+ mph vibs since I had it rebalanced

Update:

The shaking seems to have gone away for a little while. I have not felt it in a few days...... wierd

Where do you feel the shakes most, seat, steering wheel, or console? I have a 17 that shakes occasionally too.

 

Sorry if you've already mentioned it elsewhere.

Exactly where I feel it. Stinks this is still going on with the 17s.

 

Thanks for the response.

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
