You might want to check the Tension Strut in the front suspension.
Some have said that when this bushing starts to fail it feels similar to warped rotors.

Tension Strut ( also called Thrust Arm ) ( also called a Lower Control Arm Front ). This controls the lateral movement of the front wheel.
It's part #8 on the link below.

The rubber bushing on this part can deteriorate and cause a clunking at brakes. Although you would also hear a clunk over bumps and maybe while accelerating. It's a common problem on e39 BMW's too, which have a similar suspension design.

I'd climb under the X3 ( don't need to jack it up ) and grab this Thrust Arm and try to replicate the noise.
Thanks for reponse.

Just rolled over 62k so that seems a little premature.

I do NOT hear a clunking noise. I dont believe its a control arm issue. But ill have to check underneath to be sure.

Feels more like an engine stumble or transmission
