Greased mine up with some thick dielectric grease last night. Its probably 80% better than it is at its worst. I am going to play with the boot more and see if I can get it to be 100% gone.

My 2014 Silverado is at 120,000 and running just as good as day one, not one issue with it. I know there’s problems out there, but complaining to others saying “should of bought a ford” doesn’t help

Just got this from a buddy at my local dealer. Looks like Chevy is aware and they are working on a fix. Sent from my iPhone using Tapatalk

It would seem that the TSB is onto something, but they need to amend it to include earlier years.

That was my next question. Does this also involve 14 and 15 models...….???

They did put a steering column in mine under warranty. (dealer was awful). I had a steering noise they diagnosed as the column but I figured it out after it still made noise after replacement. Was the steering angle sensor.

 

Seems as if they could have disturbed the boot assembly in a way that made it worse. The truck was dead quiet prior to about 40,000 miles when they did the column.

Anyone found more info on the repair side of the TSB ? I looked up the seal and it looks like a 25-35 dollar part pending where  you price it. Totally worth no ticking if it comes to that. 

 

Side bar, I tried compressing my seal towards the end with a clamp and it must have a fairly stout collar inside the rubber as it wouldn't collapse with a reasonable amount of pressure. I think there may be a secondary seal or lip inside behind the shroud on the steering shaft. 

 

Worst case, we could make a dynamat piece that would attach to the seal or the shaft to take up the gap between the seal and the shaft and block more noise.

UPDATE:

 

My truck didn't seem to respond as well to grease as others. It shaped up quite a bit when I tried it but over a few days it returned to almost normal. I think it was getting hot by the exhaust manifold and leaking out. I had dielectric handy with a good dispenser to get up inside that but I think it may be a little less heat resistant than white lithium. 

 

This morning I made up a little cover to test. Where I work we have hundreds of plastic pipe caps laying around. I cut one to a "close" id to match the steering shaft. I slit it up the side to go over the shaft then zip tied it to the end of the steering boot where the shaft goes inside. This isn't permanent but I could see something that was designed properly helping here.

 

I think it does 2 things. The ID of the plug is slightly contacting the OD of the shaft. It A) keeps it from bouncing around down there and B) helps block noise just because an extra piece of material is there. I oriented the slit in the cap to the drivers side away from the engine.

 

This is the quietest the truck has been since it started making noise. I feel the dealer probably boogered up my boot a bit while changing out my steering column. Also, I hope the TSB listed above will maybe spark an updated steering boot we can buy to replace the original design (time will tell). 

 

I will keep driving it as is and report back if the noise comes back or stays away but on my initial test drive it seemed to be completely immune to all types of bumps/throttle application etc.

Can you post a pic of what you made?

Keep in mind this is extremely crappy and only for testing theory. I would like to build some sort of split collar from plastic or aluminum that clamps onto the steering shaft or the boot and stays stationary or spins with the shaft. Also, something more solid could House some pre cut sound deadening material.

Morning update:

 

Put about 70 miles on the truck last night/this morning. Highway and city crappy streets. Still completely quiet.

 

I can hear the slightest of engine noise at 1000-1200 rpms high load I.E. right before it would downshift to a lower gear but its likely only audible by the best of ears so it doesn't bother me at all. I presume with a nicely built piece and some deadening material on the part it would be basically silent.

Lmao, no way I would have ever thought in a million years that greasing a steering shaft would cure a throttle/load dependent noise. But I had to try. The ticking has never been more quiet.

Welp, sprayed white lithium grease around boot and..... it friggen works. Not one tick..... I was thinking about taking a piece of high heat sound proofing material and wrapping it around part of the steering column. Should absorb any reverbaration up the column.

What do you guys think?

      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.
