Sound was from the rubber bumper sliding up and down the shaft. Lubricated also really helped the noise. Haven't noticed in 3 weeks. TSB issues for squeaking from front and rear brakes. I noticed the sound and reported it to dealer at time of service. They searched and found TSB's and ordered parts for both front and rear and replaced both.

The problem was a rattle in front of the driver seat position when accelerating under load. Most prominent at 2,000 RPM. The dealer didn't recognize the problem on the first visit to the shop, so a second trip was required. After recognizing the rattle during the second trip, the dealer added insulation and tied up loose cables and clips behind the dash. This didn't resolve the issue, so a new instrument cluster was ordered.
