Vibration at 80mph

[Hoesgottaeat2]

How about the sway bar? That still there? Links? If those are good, I'd be looking at other rotational items i.e. drive shaft, u-joints, etc...

Let me look into it. Thank

Any update?

You look at u-joints, bushing in transfer case extension housing, rear axle bearings, body mounts?

I had an issue with my 2017 yukon at highway speeds - around 80 mph. I could feel it in my butt. Tires were new and balanced. I pulled the rear driveshaft down and found the axle end u-joint was stiff to move by hand. No corrosion could be seen.

I replaced it and all was good. After I pulled the OEM apart, the bearings were getting dry and rusty. Easy thing to check/fix.

Been there and done that with u-joints.
