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?

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
