Update: The Goodyear LS-2s were taken off and swapped for Michelins yesterday...I had time to run the truck today up on the highway. What a difference!! The truck runs nice, smooth and quiet....until you take it over 70MPH!!!! ITS STILL SHAKING :dunno: ........I talked to the dealer and let them know the vibrations are still present...in a weird way I actually feel bad for the dealer in that GM left them holding a leaky bag with SOME of these trucks. The dealer told me they did a traditional balance because they do not have the road force balancer.

 

Based upon my latest vibration test, I am convinced its something related to wheel speed however not necessarily the tires. (See the red spike on the attached pic in the 800 RPM range at 75mph.) That spike is on the X-Axis meaning it is a shake from left to right, (driver side to passenger side).

 

I may pop the wheels off and check the runout on the hubs and rotors with a dial indicator. Can anyone think of anything else that spins at wheel speed that I could easily check while I have it apart? I am open for suggestions!!

I think your on the right track by using a dial indicator, however I would check run out on the wheels first then the hubs. Check your driveshaft run out too if you can rig some kind of fixture. I bought a new Ford F150 in 1984, it had a nagging vibration, dealer was no help, I suspected the driveshaft, had a driveline shop inspect, it was bent and the balance weights were 180 degrees off, $100 took care of it. Only other issue I can think of would be a torque converter out of balance.......best of luck.

I have a friend that has the driveshaft balanced on each new car he gets. I do such if the new tires, true and balance and new shocks do not result in a good smooth vibration free ride.

I know it came up in this thread that there were possibly a batch of bad wheels or driveshafts. I forgot to mention that I did check the runout on the driveshaft and wheels and they were all spinning true. Obviously I wasn't able to check the balance on the driveshaft at home, but since my tires have been replaced all is well! I got a chance to get out the past few days and put some miles on the truck with the new tires and rebalance....its still good no vibrations!

Glad you found the solution.

My local dealer fixed a vibrating truck by replacing the front right cv joint.(I think that what they are still called) Unfortunately that wasn't the case with my truck, but may be with those of you who feel the vibration in the steering wheel.

Well, my truck is still in the shop for the vibration. Guess they will do software update on while its there. News said that there has been 8 fires so far.'mostly while ideling in frigid temps.

But back to the shake. The loaner I have has 20" continentals on it. Vibe hasn't been bad at all till this morning on my way to work. About 75 mph it was shakin pretty bad. Put it in neutral. That didn't change anything. Shop foreman at the dealer told me last week that the tires get flat spotted sitting overnight and have to get heated up. My 2010 didn't vibe in the mornings. Someone please edumicate on this

This definitely happens. Not so much in the summer but definitely the winter. Should stop after a couple miles...

My dealer gave me a bunch of shit today about having to test ride the truck and it won't be looked at till Thursday or later because of my vibration... And get this, they said mine was the first to come in for this reason... yea...

 

I ended up going straight to Goodyear and they force balanced the tires and found one wasn't able to be balanced at all. Plus 3 out of the 4 were WAY off. Tire will be in tomorrow and replaced under warranty without going through the dealers crap. The tire machine said the tire was balanced, but then they ran it they told me to watch because it was so bad. The machine was literally shaking laterally side to side and the machine said the tire was good at the same time... Even with the 1 tire still terrible, my vibration is almost gone, and tolerable how it is. In and out in 30 minutes and I hope this solves my problem.

 

Take your trucks to Goodyear direct and you will be taken care of immediately and then you can almost rule out the tires if your still having problems.

 

My vibration was between 72-85 mph

    • Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses too much gas. She finally got unstuck spinning in 2wd which likely used more gas than not.  
    • Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.
    • The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts. 
    • I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.     
    • Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.
