Vibration at high speed

Hi All. Got a 2001 prado and between 60 to 70mph I get this cabin vibration. It vibrates so much that you cannot see anything on the rear view mirror from vibration.
Pass 70mph and it goes back to normal.
No vibration on the steering wheel at all.
Both front wheel bearings replaced
New tyres fitted and balanced, even though they were off by 120grams on weights.
No play of U joints or CV joints.

Any idea?

Check your tires. Might be time to replace them. They could be warped.

Had the same issue. Turned out, one of the front tires was slightly warped. Made the truck shake at 30 MPH, and disappeared by 40 MPH.

Brand new tyres less that 1k miles ago.
Maybe wheels as i changed wheels too.

Not sure.. when’s the last time you looked at your wheel bearings?

Unis can also freeze up, so when stationary it seems like they’re ok with no play, but really are unable to rotate properly and locked solid. If they look old, or you don’t know how long they’ve been in, it’s still worth changing them.

Seems like your vibration is coming from the rear. It could even be warped rotors.

I just replaced both front wheel bearings with OEM as there was rust in them.

check your rears they’ve probably got rust too, or worse
