Hi all,
Looking for some advice. My 2021 Yukon SLT 5.3 w/76k miles has a new vibration. I had tires installed by my local GMC dealer 4 weeks ago ahead of a 1000 mile road trip - Continental TerrainContact HT 275/50R22. Since having the tires installed, there's a noticable vibration in the steering wheel under moderate acceleration, in the speed range of 10-40mph and rpm range of 2000-3500. At higher speeds and lower rpms, there's no vibration and its really smooth and a pleasure to drive.
When I first noticed it after getting the new tires installed, I brought it back to the dealer and they said 3 of the 4 tires were not properly balanced when the tires were installed. Lovely. So they rebalanced and claimed the symptom was no longer present. I picked the truck up the day before my family road trip, and drove the short distance home assuming the vibration was infact gone. Left the next morning and within the first 30 minutes realized the vibration was still present, but our bed was made. Fortunately we had no issues while getting to and from our destination.
After returning from the trip I brought the truck back to the same dealer. After two days, they rechecked the tires for balance and everything was as it should be. They checked suspension components to see if anything was a miss, but found nothing. They also road tested while monitoring the torque converter and nothing was found there.
In the end, they had me come drive it with the shop manager just to be sure they knew what I was experiencing. I had the shop manager put his hand on the steering wheel while I was driving and feeling the vibration and he confirmed he felt it too. However theyre not sure where to go from here. They seem confident it's not the new tires. But the torque converter and transmission and front/rear diffs are all fine(according to them). And there's nothing they found with the suspension. They said it could be a motor mount going bad or ujoints on one of the driveshafts, yet they didn't actually inspect these. To be honest, the dealership I'm using is busy, and I got the sense they weren't really interested in chasing this down, even though they are acknowledging the symptom being not normal.
What should my next move be? Could it be the tires still, and the dealers blowing smoke? Should I go to another dealer or an independent shop? Could they have overtorqued the tires originally and now I have a warped hub? Something else entirely?
Appreciate any insight provided!
