Hey guys,
its still very much winter here and I cannot get a jack under my car as everything is covered in ice and snow.

Trying to get ideas as what could be the root cause of my issue.

Basically when I drive over 45 minutes and the outside temperature is above freezing and hit potholes the rear passenger suspension becomes very noisy, as if there was a component completely loose.
Once I park the car and reuse it the next day or a few hours later, the noise is gone.

But I kid you not, it feels like a wheel is about to fall off when it occurs.....

Its a 335xi and im running H&R coilovers for the past 6 years, all year long.

Open to all suggestions!
