BMW X5 e53 Wheel Shake Under Hard Braking

[Auto Parts Guy]

So this issue just popped up a few months ago. Say I'm driving 35-60mph and I hit the brakes fairly hard, my front wheels will shake almost violently. But if I just brake normal, there is no shudder, nice and smooth. I've replaced the tension struts, ball joints, and LCA bushings, brake rotors and pads with FCP Euro parts not that long ago, within 20k miles I would say.

I have a random pop in the front every so often that I think comes from the top mount for the left front strut. It happens occasionally when I turn or hit a bump and I was thinking maybe that's what's causing the hard brake shudder. Thoughts on that as the cause?

The only thing I haven't replaced are the tie rods and I don't think that's the cause. Everything looks good underneath when I had it on the lift a couple weeks ago. All parts were tightened at K0 Lage.
