    Vibration (like buffeting) 68-73MPH new tires, 3 different shops checked

    I have not done an alignment, I asked original tire install shop and then GMC dealer to check the alignment but was told that alignment cannot be causing harmonics issue, I personally was thinking alignment is a good idea to check. Alignment was done 6K miles back with old tires.

    Vibration (like buffeting) 68-73MPH new tires, 3 different shops checked

    all shops keep telling me they balanced tires to <7 lbs of Road Force. I do get that it could be rims and maybe even tires, at this point, looks like no matter what I will be paying. Just do not want to pay in vain, already over $600 into all costs on top of tire costs.

    Thanks, for sharing, how did you find the rims damage, none of the tireshops seem able to check rims for trueiness?

    I think so too, I will try put to neutral test but somehow I do think it is a coincidence. Will try one more drain and will add small dose of Lubeguard (not sure what LG version to use in 10-speed ULV though).

    Vibration (like buffeting) 68-73MPH new tires, 3 different shops checked

    before putting new rim, local tireshop did spin the rim to check it on the Hunter machine, did not see anything wrong with it. Tires from Tirerack were 03 2024.

    Vibration (like buffeting) 68-73MPH new tires, 3 different shops checked

    Yes, thank you for this valuable tip, I will try that. Competent GMC tech instrumented and rode with me , found that on a very steep incline in very low speed and low RPMs TQ shudders but in normal highway driving in the 65-73MPH speed band no shuddering that he can record on the tester. He...

    Vibration (like buffeting) 68-73MPH new tires, 3 different shops checked

    Carwash told me - "sue me, you are not getting a dime from us, too bad so sad." Of course, I could have gone to Small Claims but those are backed up for months. In retrospect, I should have paid $650 for a new rim from a dealer. However, 4 tireshops including with Hunter Elite RFB found zero...

    Vibration (like buffeting) 68-73MPH new tires, 3 different shops checked

    Thank you for pointing out this nuance. Initially, I deduced that since no vibration felt on the steering wheel or pedals and that vibrations are almost heard/felt by ears exactly like open rear window buffeting, I felt that it must be from the rear. However, if dealer indeed rotated ( I assume...

    Vibration (like buffeting) 68-73MPH new tires, 3 different shops checked

    Hope the wisdom of the crowd will help me troubleshoot further. I am stumped. This truck was one of the smoothest riding highway cruisers, zero vibrations for 49,000 miles of any kind up until recent episode. 23 Tahoe Duramax 3.0 4x4 LS with 10-speed AT with 49,500 miles. Carwash damaged/cut...

    Anyone uses PIAA wipers on 2021+? What model # of PIAA fit 21+?

    My experience exactly, bought the AC Delco Professional 892215, it was barely OK, same problem with TLP adapter that you described. I may end up jut ordering 84278338, I was just somewhat disappointed by how fast an OEM pair failed <6 months.

    Anyone uses PIAA wipers on 2021+? What model # of PIAA fit 21+?

    Thanks, yes that is the TLP part that Autozone does not list. I also saw that Bosch in their kits lists two sizes of TLP, if one was not enough

    Anyone uses PIAA wipers on 2021+? What model # of PIAA fit 21+?

    I need a pair of wiper for my 23, OEM ones last 6 months in NC heat, claybarred the windshield, cleaned the wipers and 308ed them, no success. Keep seeing PIAA silicon is magic. Willing to try now that Autozone sells them but not clear what part fits as AZ part finder does not find my 23 Tahoe...

    21+ Yukon floor jack pad: what’s compatible for rear jack point/“socket:”

    I have the same question what locations are safe to use with a floor jack? I need to be able to do tire rotation on my 2023. User Manual does specify that only bottle jack locations are acceptable but they will not work for doing rotations as I will need to use jack stands. Appreciate pictures...

    How much trust do you have in the 3.0?

    I think GM did a decent job on this engine but poor manufacturing quality is ruining mine -it has oil consumption. GM covered their behind by issuing a TSB saying that 1QT per 1000 miles is normal oil consumption and dealers are showing you this TSB when you come and ask to check the oil burn. I...
