I asked the dealer to grease it yesterday and obviously they didn't. Will try another dealership when I have the time.

Found a kit on Amazon that has the grease and the clamps. Is it the correct one?

I do not believe it's the transmission. Shifts smoothly and the bump comes from the rear of the vehicle. Is there a viable solution to this problem? Should I just open the boot and grease the damn yoke?
They should check rear pinion angle.

9L3Z-4W602-A - Is indeed what you are looking for.

From my post in the other thread:

"If you are doing this yourself, don't be surprised if you have to heat the driveshaft bolts to get them out. I had one hang up to the point I thought it was going to snap off. It really was that tight.

Before you put them in, give them a good wire brushing and run them in and out of the holes in the flange a few times. No lube, and then blue loctite.

I didn't look at the service manual, but I suspect these are supposed to be one time use bolts."

It's a pretty simple job. Simple enough that I'd never waste my time arguing with the dealer to get them to do it. I'd rather pay for the lube and clamp and do it myself.

I'll probably end up ordering the big tube of the Motorcraft special lube and source a handful of the clamps and just keep them on hand.

Do you have links to the get the lube and clamps (possibly a tool to reinstall the clamps). Why would you have to remove the drive shaft? Maybe one of us should make a video on how to lube the yoke.

Anyone else ever feel a sort bumping sensation like someone light ran into the rear bumper when you come to a complete stop from greater than 30 mph. Not sure if its a braking issue or something with the transmission and/or rear differential.
Have you fixed the bumping sensation? I had this for awhile and just saw this thread. But all my previous trucks and SUV where the same way.

I have not fixed the issue yet. Thinking about putting a go pro camera under the truck to watch the yoke while I drive around.

Looked under truck for a good place to mount the go pro and will have to make a bracket. While there took some photos and the drive shaft doesn't look like the one in the below video.
