Noises problem V8 Four Wheel Drive Automatic 54,000 miles

I've got an '04 Expedition with about 110k miles on it. Just last week, it began making a noise while traveling at highway speeds. After a couple hundred miles or so, this is what I've observed:

The noise: has not occurred below 55 mph has not occurred above 80mph (don't usually drive above that) occurs and begins as a shift point is approached, but continues after the transmission completes the shift happens much more often while going uphill than when going downhill if allowed to "build", the noise will develop into an irregular thump that can be felt in the floor by both driver and front passenger ALWAYS goes away when I take my foot off the gas. Always. Never fails

Do you
have the same problem?

This sounds like the engine could be misfiring which can cause the car to rattle. Here is a guide to help confirm the problem.

Also I would check all rubber mounts, tranny tailshaft, motor, and even body and frame mounts. Also check the exhaust system to make sure all system hangers are in tact.

Here is a guide on the engine mount.

Patty, as a novice checking the mounts may be better left to a pro.

I have a 12k, 12 month warranty on drivetrain only, does this fall under that category, or shall I take it to my mechanic?

It only does it when the car is warm, (running more than 5 or 10 min) could that be any other concern?

As you must know, the hardest type of problem to solve over the internet are "funny noises". Yes it could be something else, but if it has a 12 month warranty, let them tell you what it is and if they will cover it, tip: Dont take no for an answer!

What is a cracked flexplate? They checked all the mounts or at least said so, but I got it back yesterday and it still made the same noise. Someone said could be that and you could end up sitting if you don't get it fixed?

It sounds like it could be the starter bendix return spring is broken and hitting the flywheel. I would remove the starter and check it out.

Here is a guide

Here is what it will be like for your car (below)

Please let us know what happens.

No noise on startup, It ONLY happens when the car is warmed up and is accelarating or going up a hill.

I am going to suggest that you have a starter motor that has a broken return spring

If its not the starter there are two technical service bulletins on Expedition and Navigator, both for suspension problems, one is related to the compressor being too loud, and too much vibration, the other is for ride height sensor arms disengaging from the control arm on the front, or the axle on the rear, is the truck leaning to one side? Or sagging in the rear?

No there is no sagging of any kind. Did notice now that the front end is out of alignment. They are having a tough time figuring it out until they removed the starter and BAM! You were right :) I am so happy thanks 2carpros!

Vibrations can travel to other sites, but this is a known problem, so lets start by checking that. Any brake work on the rear brakes yet? A severly warped rotor will be felt in the seat area.

Alright, I understand the troubleshooters suggestions, and could all be relative, but they are off. The vehicle exhibits a clatter like a torque converter failure, turbines clashing under the floor. Sometimes very loud even pounding on the floor like something is about to explode. It relates to torque and engine RPM. My expedition was (is) doing the same.
It is also an 04. Identical Symptoms. Found the blog looking for hints. I took mine to a reputable trans shop. They indicated it was definitely a torque converter. So I put in a new transmission and TC myself. Same Symptoms. Going up the Grapevine (a Hill in Cal) it grows worse and worse with the only adjustments that help is to decel. Downshift, Decel, so at second gear, at 30MPG, my car goes up the Grapevine. Did not try the AWD. A mechanic friend of mine, asked another about a similar problem with the same. He indicated it was his Transfer Case. Before I drop hundreds more, I needed a tie from the RPM to the Transfer Case. This blog saying it only does it in 2WD is my key. It is the Transfer Case or Flywheel, I glanced at the flywheel when it was apart and I saw nothing out of the ordinary.
