Sorry for not getting back around to following up! I rarely drive my Expedition as my wife has her car and I have my company vehicle, so the Expedition kind of ends up the "third wheel" (so to speak!)
Anyway, here's how things worked out...
I tried the test as suggested - getting the car to the point where it was rumbling, and then braking to see if it went away. It didn't. I then re-read the instructions and found that I was supposed to take off O/D! So I did that.
Strangely, with O/D off, the car didn't rumble! I thought I found the cure for the rumble until we were stuck in traffic this weekend and it was moving right at 38-42 mph. I normally keep the car with O/D on (as it doesn't seem very smooth with O/D off) so when the rumbles started, I turned off O/D, expecting the rumbles (and shakes) to go away. They didn't.
It was kind of a blessing in disguise though as I was able to get the car to rumble with O/D OFF and then tapped the brakes. That seemed to make the rumbling go away. I say "seemed" as I couldn't get it to dependably reproduce itself as I tried it.
My wife finally got exasperated of the car shuddering with the O/D off and demanded I turn it back on: "I'd rather have it have the shakes than this!" So that was the end of my testing.
Pretty wild! I am pretty much thinking it's the torque converter. Does that sound about right?
Thanks for all the help!!
