A few months ago I had a new set of Tires installed and ever since then My S-10 Extreme started having a Drive Train Vibration.

 

The tires where even replaced with a different set.

 

My Local Chevy Dealership has been unable to find the cause of the vibration

 

it's really bad around 55 MPH

 

It's very uncomfortable to drive....

 

Any suggestions on what to look for or do?

 

Thanks,

Are your tires balanced properly ? :thumbs:

I've found most garages in my area don't know how to properly balance a tire. If so check your driveshaft angles this would be the next most likely source of vibration that I would check. hope that helps, good luck :seeya:

Tires have been balanced about 4 times now.

 

from where I bought the tires and the chevy place.

 

chevy place has checked Transmission, Drive Shaft, Rear End.

 

nothing is out of specs.

not likely but your alighnment coulld be severly out of wack. also how well do you trust the techs at your dealership. I had one call to ask my roomate where he kept the key to unlock his lugnuts. (they are factory installed and are under the rear bench next to the jack) why I knew this and a certified ase mechanic didn't is beyond me :seeya: But as for your problem I'm kind of stumped. um oh yeah just wondering what type of tire ,size and does it vibrate over 55mph or just at 55.

my whole cab shakes like a mofo when I hit the brakes at 45 but only at 45.

I know my rotors are warped but I've been procrastinating. sorry I couldn't be more help :thumbs:

The vibration is felt in the seats and the console shakes the side mirros shake.

the steering wheel doesn't shake at all.

 

I feel like it's in the rear end somewhere....

This is a known issue on the later model S-10/Sonomas with the extended cab and the Zq8 suspension. I

s your Xtreme an extended cab model?

 

There was a detailed thread somewhere on www.s10forum.com about this, and I believe the issue was the hop shock was not tightened down, or it had to be replaced, or installed if for some reason it was not on there from the factory.

 

Let me know if it is an extended cab model. I'll try to find that thread and see what the resolution was.

Have you lowered the truck at all? I could see if you did anything like that you would be changing pinion angles which can deffinetly cause driveline vibrations. You could try to take your driveshaft out an d rotate it 180* and see if that helps. Your dealership has tested the torque converter too right? Check the engine mounts, transmission mounts and all suspension components. Let us know what you find.

It is an Extended Cab S10-Extreme

 

comes from the factory lowered.

 

just strange that I've never had this problem for the first 50K miles

but since I put new tires on it I have.

 

The Chevy place says they checked everything.

 

They have again this week, they seem to think it's a Tire or Rim

thanks, for all of the responses

 

According to the Chevy place it's the TIRES, 2 of them are way out

of road force variation

 

I will never buy tires from JUST TIRES again...

 

...now I have to go argue with them...

 

Thanks again

Wow, this sounds real familiar. I have a '98 Chevy Blazer.

I had four tires replaced about three months ago and

got a wheel alignment at the same time.

It would give a little shimmy around 75-80 MPH. It

is kind of hard to give that complaint to the tire

dealer. Anyway, my tires got progressively more

noisy. And, the inside of the front right showed

excessive wear.

 

I went back and they found my Blazer to be out

of alignment (that's weird, they just aligned it

three months ago). They realigned it

and rotated my tires. They mentioned that the

idler arm had some play but they don't stock

the replacement part because it was only a

tire dealer.

 

Anyway, the noise continues. It is almost

unbearable. I tried to pin the noise down to

a particular tire by changing with the spare

one tire at a time. The noise never went

away. Apparently, it is more than one

tire making the noise. By the way, the tires

are Bridgestones.

 

But, as I was changing the fronts, I noticed

a LOT of play. I could probably move the

jacked up wheel left and right by at least

one degree in each direction. The tolerance

is one degree; I've got at least two degrees

of play. The play has got to be out of tolerance.

 

So, I've got an appointment with a Chevy

dealer on Thursday to get the play out.

Hopefully, I'll start to see some improvement.

We'll see.

Good idea on the driveshaft check - it's quick. Just need to take out the 4 bolts front and 4 bolts rear to drop it out and check the joints. If they do not pivot smoothly, you will get a mean vibration that you can feel even just backing out of the driveway.

My girlfriend has a 98 2WD Jimmy and it has a bad roar in the front. Tire store says it is the hub bearings and they want $800 to do both sides. They showed her excessive play. You might have bad bearings also. She has had some vibrations when braking heavily also.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      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.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      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. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      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.
