Highway Speed Drone/Pulsing Vibration
05 GX470 93K Miles. Feel it around 50-65mph. Very noticeable when decelerating (Foot off gas pedal, no brakes) from 70mph.
Sounds like a resonance through the front. Tires are new and I don't think it's tire related.
any thoughts on what this could be? Car is very smooth otherwise

Pole Position
A couple of ideas:
- loose exhaust
- worn ball-joints
Both can be checked by putting it on some jackstands. For the ball joints, grab each wheel at 3 & 9 and rock. Looseness will be tie rod joints. Then grab at 12 & 6 and rock. Looseness will be ball joints. For the exhaust - get under the vehicle and (when it's cool!) shake it some - see if there's a bad rubber hanger maybe.
