I had not noticed this at all until the day after a big rain and we were driving through a bunch of deep water, (sometimes at speed ) At no time during the drive did I feel / hear anything terrible happen, but starting the day after, this vibration is now a daily occurrence.

The vibration only lasts a few seconds and then stops. I will be trying to use my GoPro to film the suspension / engine bay components to see if i can determine what might be causing the problem.

Anyone else have any ideas?

Problem does not occure in rapid acceleration or other speeds.
