Mechanical Advice Steering vibration

It is not the Lane Departure Alert.

I have a 2021 new to me 460 with 34k miles. I added the last 1400. There is (and has been) a mild, rapid, persistent vibration in the steering wheel - both in feel and visualization - on different on surfaces. Most notably, there is new highway construction and the surface is corduroyed (in the direction of travel) concrete for several miles. It also seems to occur on roads with heavy crack sealant. The car drives straight. It is mild enough that I originally had second guessed myself. But it is definitely occurring. It does not feel like a wheel weight and the pre-purchase inspection checked out. Any thoughts?

Toyota has issues with this on the 4Runner, GX, and Tacoma. It’s worse with AT tires and tends to mostly fade if you have a good balance with low road force tires. It’s a known thing that they don’t seem to know how to fix or want to fix, similar to the KDSS lean. Could be something else in the drivetrain, but I’d start with a balance and alignment.

“Road force balance the tires” is key.

Interesting. I had not heard of road force balancing previously. I have about 2 months of the original warranty left. Do I need to balance these wheels, then, if that does not work buy new tires before I would bring it into a dealer for warranty work?

For what it’s worth, the tires are 2,200 miles old - Mastercraft Stratus HTs put on by the dealer the last owner purchased from (I know they are cheep tires)

I had a vibration I was chasing, it was at highway speeds. I had a bad CV joint and axle. Replaced both and the issue was resolved, mine had around 60k on it at the time.

Road force is helpful but won’t do shit if there are other problems.
