Vibration/Wobble - cannot find the source

[Annolino122]

Been chasing a periodic vibration for over a month now. Steering wheel doesn't vibrate, it's been aligned and drives straight, no squeaks, rattles, knocks, nothing.

Happens at a variety of speeds, not just the tire resonance speeds (40-55mph).

2021 with 51k miles

ICON Stage 7

35" tires (Toyo AT3) on 17 ICONs

I've gotten the wheels/tires balance 3 times, even having them undo and redo them, road force balance, etc

I have upgraded linkage and arms in the back, so I did the heim joints and bushing rebuilt and replaced.

Grease the drive shaft

Brake pads have been replaced around 5k miles ago

Its not going away, all I can think of is the wheel bearings or the rotors are somehow already shot but they don't show any signs, no wiggle or warped parts

Any ideas of what else it might be? Maybe I think it's the back instead of somewhere else?

I am at a complete loss besides what I mentioned or maybe the tires are out of round (so they'll balance fine but won't drive okay)

Drive shaft angle might be worth looking into.

Tire delaminating/ or broken cord?

On 35s suspension geometry starts to be a real thing. check all of that, also, check driveshaft for something wrapped around it. carrier bearing failing will also cause a nice vibration. good luck man!
