2016 Silverado 1500 Rumble Noise and Slight Vibration

Hello,

 

I recently purchased a used 2016 Silverado 1500 crew cab and i'm running into an odd issue.

 

At highway speeds mostly 64-68mph but also anything above that speed will trigger a low rumble and slight vibration. The rumble is always there but in a pattern... whoom......quiet.....whoom....quiet.....whoom with about a second in between the whoom and quiet.

 

- Tires have been balanced...

- Dealer said its my aggressive tires.. I strongly disagree

- Driveshaft shop said they can hear/feel it and have looked at about 40 trucks just like mine and have not been able to pinpoint the problem. He mentioned he could balance it but he didn't think it would change anything and didn't want to waste my money. They also strongly disagree that its not the tires.

- Another Mechanic said he could also hear/feel it and is about 80% sure its my torque converter... he also suggested once the torque converter is going out the transmission is right behind it. I'm hesitant on this only because its a costly repair...

 

Any suggestions? I would greatly appreciate it!

I have something very similar and thought it was the torque converter.   Still under warranty and was going to get it checked out next oil change.  You have the 8 or 6sp?  I'm only at 30k miles on my 2016

My '14 has a similar issue....when the motor is still at low operating temp and at 55 to 65 mph, I can feel a buzz that comes and goes about 3 seconds apart but disappears after fully warmed up. Also did it before upgrading to new tires....weird.

Sounds like we have the same problem.  Let me know what you figure out!  If I end up at the dealer before you I'll update you here.

Do you hear the problem more than feel it? I hear mine more so than feel it... really really bugging me.

Honestly I hear and feel it. Not sure which more.  It happens every 3-4 seconds when it does.

when it happens, if you set cruise at the speed its happening at will it just keep doing it or go away? i can set my cruise at 66 and it will do it the entire time but still in the phase of whoom...quiet...whoom...quiet...

I have the exact same issue. I'm having it looked at tomorrow, but it's supposed to be raining so we'll see what happens.

 

I also have this sputtering sound issue described in this other thread:

https://www.gm-trucks.com/forums/topic/237090-sputtering-while-coasting/

I don't feel like mine has a sputter or shutter feeling. It's just a deep base kind of sound and slight vibration... 

 

Took it to another shop on Saturday he disagreed on the one shop telling me it may be the torque converter... he suggest I got the tires balanced again and lower my PSI from 45 to 35. He suggested not to get the balance done at discount tires like I did before. He also said my drive shaft did have a little play in it. No one really has an exact answer for me it seems like a guessing game.

 

I'm thinking of swapping wheels/tires with a friend and seeing what that does to at least narrow that situation out.

Where is the mileage at on the truck?

 

If it is the 60000 range, I would say torque convertor, test you can do is a find a slight incline, get up to 45 MPH and keep it there, if is the torque convertor, you will feel a vibration like you are running over "rumble strips".

I'm at 75k miles.. it won't do it at 45... the lowest speed its done it at is like 55... I found 70 is a sweet spot and won't do it. but 60-68 is the worst!

You may have the dreaded Chevy shake.

Took it to another transmission shop and he is 100% sure it has nothing to do with the transmission or tires. he said that its the driveshaft... going to take it to a driveshaft shop and have them work on that and go from there.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.

      To me it honestly makes zero difference what filter you run. It's not a race engine, just a truck engine that's mostly bumming highways and it just needs a filter that filters oil.   The filter used to be a 7060 and the long version was a 7045. Now it's the newer updated filter that the K2XX trucks and newer run, the 100255 I believe if we are using napa numbers. Any of those filters is going to do the job.   I wouldn't overthink it, to me it makes no difference because those first filter numbers worked for 18+ years before the spec suddenly changed.
