Noisy NEW KO2's

[southof30A]

Just got a new set of KO2's installed on my 2018. Original set got 55,000 miles. I am getting a rather noticeable tire drone from the left front on my new tires.

Tire droning is from left front and was there immediately upon installation of new tires.

Truck was aligned with new tire installation.

Rebalanced and rotated all 4 tires with no change in tire drone noise.

Now have 2,000 miles on new tires with no change in drone.

Pitch of drone changes with speed.

Noise goes away during right hand cornering.

Left hand cornering does not diminish noise.

No vibration in steering wheel.


I would welcome any advice. Thanks in advance.

Driver side wheel bearing 100%. Ask me how I know...

Like nikhsub1 says, wheel bearing. Had this happen to me twice on various Swedish vehicles.

I gotcha. I appreciate the help. My thought was wheel bearing too, but was stumped as why only showed up with the new tires. Maybe the old skins rattled and rolled enough to cover up any noise.

Maybe - they are weird those hubs, they just all of a sudden go. I could have shit the bed when weight was removed from taking the wheels off. I was sure my noisy hub was bad tires at first, so much so I got a new set. When I still had the hum, I knew it was the bearing. Swapped it out (easy job too) and now she is nice and quiet and smooth.

If the noise goes away in 4WD it’s the IWE, if it’s persistent then wheel bearing

Could be hub. Mine was a small re-alignment of the real wheels and it went away.

AFAIK there is zero alignment in the rear?
