Vibration at highway speeds (not alignment)

[Bgallagher]

Hey everybody. I was traveling in my Equinox over the fourth and I noticed a light vibration coming from my driver's side of my Equinox. I also noticed the vibration would get stronger when I was slowing down at highway speeds (between 50-70 mph.) I have had an alignment done and my brakes are fine. I believe it could be suspension related but I leave it to BITOG's expertise to help me!

What kinda tires?

I'm suspecting a shifted belt/runout problem

Rotate the tires from side to side to see if the vibration moves to the pass side. I once had a chunk of fresh pavement stuck to the inside of a rim that caused a balance problem.

I would suggest check of the rear wheel bearings on your Equinox. FWIW

If not uneven tire wear or balance issue, check the carrier bearing if it is AWD. Carrier bearing failure is very common in this generation Equinox.

Definitely check the bearings

Maybe you lost a lead weight that you did not even notice and the balance problem shows up significantly at that speed. I see weights all over the roads. Especially near turns where people rub their tires. My daughters have also bent their steel rims on pot holes and man hole covers, and alignment issues

Hankook H727s. I have had them for about 2 years now without any issues.

I had one my old cars do the same thing. I finally found a huge bubble on the inside sidewall. Swapped the tire out and it was back to normal.
