2023 XLT
2023 stock xlt 16k miles. Just had the truck in for an oil change and tire rotation at 15k, I don't think that matters but after leaving the dealer I noticed a thud when accelerating. I'm pretty observant and I know it did not happen before the dealer.

The thud doesn't happen every time but when it does happen, it's usually after coming to a stop and then about .5- 1 sec after taking off. I'd say once every 10 stops I hear it. It's kind of driving me crazy hearing it.

At first, I thought the suspension could be bind from being lifted off the ground, a weird transmission shift, or maybe gas in the tank, but it sounds more like a thump and not a slosh.

Today I crawled under the truck and was pushing things around, When I hand turn my driveshaft, it makes what I think is the sound. Is this normal or should them be some type of lube to quite it? Thanks.

Thanks for any help, this is my first Ford so I'm a little nervous about any odd sounds I get.

It's the slip yoke on the end that goes into the transmission, most come delivered pretty dry. Unbolt the driveline, clean out the spines and re lube.

As @astro_fusion stated, that seems to be the most common cause for what you have going on. Most of the people recommend using the Super Lube with PTFE.

Your right on the money with your video ! Be sure to use PTFE Grease ! Super Lube PTFE works Great !!
