OK, so...

 

I know some folks think the ring and pinion in the rear diff is the cause of the vibrations in our trucks. Some of you have had them replaced by GM...but how do we know the replacement parts aren't also out of spec? After some research I found two aftermarket replacements, one by Motive Gear and another by American Axle. Anyone adventurous enough to try one of these?

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Getting very discouraged with my new truck shopping! GM... Get your Sh*t together! I had a 2011 LT All Star with 20" wheels..... for 30,000 of its miles I had a bad vibration with it, smooth road vibration! It had the Goodyear LS2's on it, through the course of time I had several tires replaced by the dealer, didn't resolve! I eventually said screw it and put Michelin LTX M/S2's on it... it not only solved the vibration issue, the truck rode impeccably! I now loved my truck! I kept it for another 16 months. Not a vibration at ANY speed whatsoever!

 

I sold my 2011 nearly a month ago... I am in the process of searching for a replacement. This is the discouraging part....

 

I found (2) 2015 Silverado's that appear to me, both High Country models, one of them with the chrome 20" wheels (yes, with the garbage Goodyear LS2's & the 5.3 6spd trans, the other truck with GM's 22" wheels that have Bridgestone Duelers on them & the 6.2 8spd trans. I demanded that I road test them on the expressway, on varying pavement types... THEY BOTH HAVE VIBRATION ISSUES ON SMOOTH PAVEMENT! The 20" Goodyear LS2's being the worst! A $56,000 MSRP truck, the $62,000 MSRP truck vibrates as well.... not as bad!

 

I highway drive, this is insanity.... I need a truck, the current incentives are expiring this Friday July 31, 2015... who knows what August will bring. Who knows if I do buy, if the issue(s) will be resolved?

 

Do I risk, do I shop elsewhere?.......

 

Puzzled about this FAILURE of "Quality Control" GM.... SHAME ON YOU!

 

I regret selling my 2011...

 

I won't get a Dodge, but I may entertain a Ford. I am from a GM family, parents are both GM retiree's and I had 11 years there at Cadillac HQ in QC.

If I remember correct American Axle is who makes the gears for GM in these trucks.

That would trouble me too but I would still want to see what kind of deal I could get and take it from there... Mine has the GM 22" wheels with the Bridgestone Duelers and had the 70-75 mph vibes, but after a tire rotation and re-balance it has been fine... I realize it may come back but I am happy for now... Of course getting the truck for 13.5k under MSRP and what they gave me for my 2004 Avalanche helps a lot... If the numbers are working for you, make the deal contingent on the vibe issue if that's possible?... Have them fix it before you sign or look for the same truck elsewhere... May give you more time... Good Luck to you...

no they had the regional GM rep drive my truck, he is saying that everything is "normal operation" and they are refusing to do anything. but while saying that everything is "normal operation" he said that I have drive train vibration, go figure. it was him who recommended that I drive in "M5" to reduce the vibration from the AFM and that was relayed to me through my dealer service rep. I have been trying it, and it has absolutely killed my fuel economy. So apparently they don't want us driving our truck like they were designed to be.

 

What kind of driving do you do? is it heavy traffic (stop & go) or real freeway?

both... most of my time has been spent on the freeway going 80+ so it is getting over 20 then...unloaded

make them put on the vibration computer... they have one and they just sent out a new software update for it. It will tell them exactly what is wrong with it. A regional rep is not a machine. Or find a dealer that has one and will put it on and go for a ride. They have certian frequencies that point to what is wrong... like earlier it wasn't tires it was the rear end and it was fixed for about 3k miles then the vibes came back and the computer tells them now it is the tires again... you would think that they would just replace those crappy tires and be done with it... for whatever reason they just do not go with these trucks...

It was before Taxes and Shipping... There were no Fees... It was the simplest vehicle I have ever purchased... Bought it off Ebay from Jim Faulk Motors (jfmnational) out of Missouri... After Rebates, Incentives and it being a DEMO model with 1800 miles on it, the MSRP was 53k and the Ebay Ad was for 40.5k... After a few phone calls and not even asking, they went down to 39.5k.. The phone calls were about shipping and talking back and forth with the wife... They do their own shipping and it was $800 to NJ... I still had to pay NJ taxes when I registered the Vehicle... Rod was my Salesman and was awesome... I asked if I wasn't happy for what ever reason upon delivery what would happen... He says politely "Sorry it didn't work out and have a nice day"... NO cost at all for shipping and a refund of the $500 deposit... Just checked and they have (2) Black Brand New High Country's for 10k under MSRP.. Here's a link..

My differential was replaced the 6th visit in. The Pico Scope detected vibration and my dealer replaced the parts. The issue persists....

 

I talked to a salesman who said he has seen this issue a few times , always on Sierras with extended cabs and NOT crew cabs. Also, the trucks with the issues had the chrome 20" SLT wheels. Everyone fit this criteria or are there other types of body styles / options having the shaking and vibration issue?

 

 

Sent from my iPhone

mine is a Crew Cab.. did they replace parts or did they get a new rearend? Mine was rebuilt from scratch.. if they just replaced bad gears they didn't fix it those gears get worn out but the root cause is the housing itself.. they need to replace the whole assembly preferably order a new one unless you have the 9.5" 3.73's then it is a piece by piece rebuild.

mine does have the 20" chrome wheels though... but that isn't consistant either.

      BAK MX4 EZ-Lift Install and Review

      By parthery · Posted

      I've been eyeing an upgrade to my tonneau cover for a bit now.  Intrigued by the BAK MX4 EZ-Lift with the torsion spring and went for the upgrade.  Thoughts and musings during unpacking, install and a few days of usage.   Once my order went into Realtruck, it took about 4 days to ship.  Unfortunately, FedEx Ground destroyed the box and contents and it was unusable upon receipt.  To Realtruck's credit, one email with pictures and an RMA was sent to me to send the first one back, and another unit was shipped out.  It arrived 3 days later, unscathed.   I opened the box and it looked like every other BAK MX4.   Biggest differences are the rails and retaining clamps, and of course the spring attached to the cover itself.     NOTE - if you are upgrading from a MX4 to the EZ-Lift, you will have to replace the rails.  The EZ-Lift rails have a notch cut in them to allow the new style retaining clamps to fit properly.  The new retaining clamps also have 2 knobs/carriage bolts and there are two tracks underneath the front panel. The strap clips are mildly different (more like the Undercover Flex clamps) in that the screws go in from the underside.  Personally I prefer these over the BAK clamps that use the nutserts that are a nuisance to install.  The remainder of the parts in the box (drain tubes, rail clamps, and bumper pads) are standard issue BAK.     I did not replace my front bed seal at the time because it seemed to be in decent shape.   BAK recommends shims on the GM trucks unless you place the clamps on the flanges about 1/3 of the way in from both the front and rear of the bed.  I shimmed the front and the middle, and initially placed the clamps equidistant.  This also turned out to be a mistake, because when I set the cover in place, the new style retaining clamps wouldn't clear the front clamp.   New style clamp inserted in the track:     And the issue which occurred because the front rail clamp was too far forward:     Once I removed the shim from the front of the bed, and slid the clamp back to the front flange, everything cleared fine.     The cover set on the rails without issue and I installed the strap clamps.  After I completed my adjustments, I pulled the pin to activate the torsion spring.  Mistake #3 on my part.  PULL THE PIN AS THE VERY VERY VERY LAST STEP!  The reason is, once you pull the pin, the torsion spring is activated.  If you have to loosen the front clamps and adjust the cover, the front panel will - by virtue of the spring, refuse to lay down.  The only way to get it to lay down so you can reinstall and tighten the clamps is to fully open the panel against the back of the cab, which will then allow the front panel of the cover to lay down and be tightened.  Not a big deal unless you haven't installed the foam pads yet (typically the last step) because minus the foam pads, you will need to place something between the frame of the cover and the back window so it doesn't get scratched.  The next time I install one I will install the foam pads before I pull the pin and activate the spring.   After using it for a few days:   The spring assist is great.  You literally can open it with one hand.  My shoulders aren't getting any younger and this was part of my motivation to swap out. The second panel latches and unlatches itself as you open and close the cover.  Neat in concept, however it took me a minute to get used to closing the cover and not hearing the "latching" sound that would tell me it was locked in place. The paddle handles are a huge upgrade and I wouldn't be surprised to see them become the standard across the Realtruck line.  They effectively eliminate the concern that a thief could coat hanger the cover open and get to the contents in the bed. I'm not sure why the very front panel on my cover has a different finish from the other 3 panels.  I have a request into Realtruck to find out if mine was not manufactured properly or if it was by design.   All in all I'm pleased.  Same level of protection, looks good, keeps stuff mostly dry (they all leak around the tailgate) and easy to install.

      PF63 Oil Filters Going Away?

      By Chuck FB · Posted

      Same here, first I bought a few filters to get me going right after I bought my truck to do some short distance initial oil changes, then realized I could buy a case lot for less as they drop the price if filters or trans oil etc is bought by the un opened case lot as well as the discount for buying the vehicle there. So I have filters for a while but its good to know going forward, knowing to expect it to be a different part number and looking filter at the dealer and not be confused over it and think they are handing me the wrong part.
