Damn ok, glad I’m still under warranty. Made an appointment with my dealer tomorrow will update with what they say.

If it does not go away in 4HI, it could be this
October 25, 2016 MANUFACTURER COMMUNICATION NUMBER: T-TT-0424-16
Components: WHEELS
NHTSA ID Number: 10132884
Manufacturer Communication Number: T-TT-0424-16
Summary
TT: Front Brake Vibration Key Points: * Issue can occur at any time if improper torque is applied on lug nuts * Over time, even one lug nut over or under torqued, can cause a vibration issue * When lug nuts are over torqued, this causes the rotor to have a runout out condition which can lead to brake vibration concerns * Brake vibration issues can occur at parking lot to highway speeds * Brake vibration issues can occur at light to moderate braking * Tightening lug nuts in a star pattern method during the torqueing process will assure that even/equal pressure is applied across the rotor hub surface * Torque sticks/wrenches should be used to apply accurate torque values when tightening * Do Not use impact guns/ratchets to completely run lug nuts up to the wheel surface

Braking or not has no impact on the issue I’m experiencing. The issue wouldn’t go away after I let off the gas like it does now.
This is the exact thing I experienced on my ‘19 Off-road Premium. I hit 50 and it starts vibrating the wheel and footwell. I let off and it goes away. I checked 4H and it didn’t do it. Coasting won’t do it either.
So my question would be how safe is it to drive like this?? I’m not familiar with needle bearings or the like. Thanks.

I have the same issue and only have 6k miles on my Runner. Right when I hit 50mph the steering wheel starts shaking up to 60mph and then it stops. Note that there’s is no sound associated with this vibration.
My question is once you brought your car to the dealership have they been able to fix this issue and if so what did they state the problem was?
Thanks in advance.

this sounds like the wheel balance issue. 4runners are incredibly sensitive to wheel balance. they need to be road force balanced with a haweka adapter and with the smart sensing functionality (whatever it is called) off for more accurate readings. It is an issue i've battled a lot with my t4r (got worse with aftermarket wheels and heavier tires).
Update;
Just as bigbwb, the dealer called me and stated they could not hear the noise or feel the vibration so I took a drive with the service manager and he did in fact notice the noise as I was driving.
Service manager said it sounds like a front wheel bearing so they are replacing the front driver side wheel bearing.

Interesting. Do you think it’s odd that it’s wheel bearing? I know with my issue if I let off the gas, the issue dissapears. I can’t imagine the wheel bearing would be effected by engine torque like the front diff is? I would imagine that if it’s a wheel bearing issue the sound/vibration would exist regardless of the engine torque/gas pedal application. But then again, I’m not a mechanic, ha!
Yes, I do think it’s odd since I have the same exact symptoms as your 4Runner.
But like you said I’m not a Toyota mechanic (although I do have an extensive background in that field) lol so I’m sure after they fix the bearing, the issue will still continue.

Well between our two dealers, lets hope one of them gets it right so we can get this issue resolved
. My appointment for the diff replacement is Wednesday. I will let you know how it goes. Have a good weekend!Does it feel like a wheel bearing, if the tire is off the ground is there play in the hub?

Does it only happen when it is is sub 40 degrees outside?

This is the TSB ........ http://im.toyota-4runner.org/attachm...ical-noise.pdf
I'm not absolutely certain. I live in Minnesota and I'm pretty sure it's been below 40 degrees since it began. I have an appointment on Friday at the dealership to get it checked out. My wife's 2014 SR5 does NOT have the same problem, though.

I'm very curious to know how this works out for you. I brought mine in today but it was 45 degrees outside so the noise and vibration was very minor. I have to bring it back on a colder day to prove it to the technician. Too mild here in NJ the next few days.
I’m actually at the dealership right now. I rode with a service manager who agreed that there’s something going on. It’s being looked at...I’ll report back with an update when I find out more.

I actually had the needle bearing replacement done yesterday.
It made a world of difference in the sound (gone) and vibration (gone). I had to prove it a tech with a ride. He noticed it right away. Had him put it in 4hi and asked him if he still felt/heard the vibration - he didn't - Pointed out the TSB (there is rev that includes '16 & '17 models). The parts had to be ordered.
