I just replaced my Nitto TG's with Mickey Thompson ATZ's same size (285/70/17). After they were balanced and installed I started to feel a subtle vibration at low speeds. To be exact, the vibration is in about the 5mph window. While braking and after take-off. I can feel it in my seat and it feels/sounds like it is coming from the rear of the truck. It doesn't shake the truck, but it is a high frequency subtle vibration. Kind of a "deeper" tone if you will. No other vibrations at high speeds or at any other speeds (while braking or not). I took it back to the tire shop and had them drive it. They felt the same thing, but had no idea what it could be. Before I take it to the dealer I want to know if anyone has had any experience with this problem...if it is a problem. I have read a few things I found via Google that suggest it might be a problem with the driveshaft/u-joints being out balance?? I got under my truck and checked for play in the driveshaft, but found none. It has never happened until I got the tires put on. Truck has right at 40,000 miles. Any help is greatly appreciated.

 

My truck is an '07 1500 Extended Cab with a 2" leveling kit, 17x9 aftermarket wheels, and 285/70/17 tires.

No... its the aftermarket wheels.

 

The aftermarket wheels don't have chamfers on the back side for the retaining clips that are put on from the factory to hold the rotors in place on the assembly line... this results in exactly what the OP is describing.

 

Take your wheels off, remove all of the clips that are around the wheel studs (diagonal cutters does a good job), put the wheels back on, torque, and you're good to go.

aaaaaahhh yeah, if they're the same wheels that he had on there previously then its probably not them.

 

We see these types of posts so often that i may have jumped the gun as soon as i saw his last line where he mentioned aftermarket wheels :P

I have had the wheels for 3 years so it can't be them. I read about that trying to figure out my problem though. Thanks.

 

govtech - I read up that it might be because of the agressive tread "thumping" at low speeds? Is that what you mean or might it be a balance issue?

 

Matt - You had these tires. Did yours thump at low speeds?

I did not have that issue with mine... they were smooth.

 

You said its predominantly the rear? Rotate them to see if the noise/vibe moves to the front.

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
