As of 10/8/2015 my local dealer and GM engineering replaced both rear shocks. 4 Goodyear LS2 tires and rebuilt the rear differential with new ring and pinion and bearings. They ran the truck with the pico meter and it was within spec.

 

I drove the truck and the vibration seemed to be gone. The thing I notice now is that on poorer quality roads the truck picks up a lot of road vibration. On the smooth, quality roads the truck drives smooth and great. Even while going up to 80mph.

 

I can't call it 100% fixed because from time to time I swear I feel a vibration. I can't tell if it is the truck or the road 100%.

 

So lets call it 98% fixed just to be safe. It certainly is fixed enough where it is not longer unpleasant to drive the truck.

 

Hopefully this helps someone else. Good luck getting your vibration in your GM truck fixed!

Year 2014

Make, Chevy

Cab, Double

Box, 6.5

Engine 5.3

Transmission 6 speed

Rear Gear. 3.42

Speeds the vibrations are present: about 40 mph to 60 mph; more noticeable when decelerating

Solutions: I noticed the viberation around 7000 - 9000 miles. at 18000 the dealer said 3 of the 4 goodyear sra's were out of round and I replaced the tires with 275/60R18 Michelin LTX at's (The truck has a 1.5" leveling kit). They didnt ballance them correctly the first time at the dealer so after having a tire shop ballance them the vibration was 65% better and only noticeable between 45-50 mph. I thought this was much more liveable. Now at 26000 miles, im noticing the vibration is back to the 40 mph to 60 mph range again.

2014

Chevy

Crew Cab

5.3 6 speed

3.42

20" wheels

Vibration over 74mph...Balanced Tires 4 times, road forced tires once, still vibrated. Took tires and wheels off of brand new truck off the dealer lot, still vibrated, put my tires on the new truck, didn't vibrate according to the dealer. New drive shaft, still vibrated.

Now have 43,000 miles on it and have given up. About to buy new tires because the stock goodyears are about wore out hoping new tires will help a bit. I only have to deal with it for another 18 months then I get a new vehicle.

I have a 2016 Chevrolet Silverado 1500 WT 4x4 8 foot bed.At 65+ mph the vibration is stronger.Had it looked at twice by the dealership I purchased at.All they did is road force balance both times with no change to my truck.Contacted the dealership for a third time and made an appointment.Service manager stated he would have my truck picked up and leave me with a rental.This appointment has came and gone today (4-4-17.Called this morning to confirm and the service manager was out sick and nobody was aware of this appointment.Was told I would get called back and nothing!So frustrated with this whole thing.Has 6500 miles on it now.I Have been a loyal GM consumer as long as I can remember.Starting to rethink this loyalty and passion I always had for GM.

No, I didn't replace the bearings. They seemed fine when I was inspecting them. I did replace the seals though. Does yours have the rear end shake? My shake was coming from rear end and I never felt in the steering wheel.

Sounds like a problem with an individual not the brand. Welcome to the forum and good luck with your truck. I have been a GM fan for many years and have never experienced this vibration issue on a new truck. Some of my older vehicles have had vibration at higher speeds but always fixed with tires & balance. It wasn't too long ago when 8 ft. box's were the most common sight. Now they stand out. Any pics?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

      Exhaust Question

      By newdude · Posted

      Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
