Thump noise when braking.

[ocalarick]

I had a loose spare tire that was giving me the "bump" during slow breaking. Can't hurt to check.

Was diagnosed as the transmission output and ting ring needed to be greased. There is a Ford bulletin about this I was told.

If your invoice has a TSB, can you post it? It may help somebody in the future that has a similar issue.

Here is the Bulletin they showed me:

Thanks for for the update JL216. Did yours make the thump on every coast/brake down?
I've only heard mine do it a maybe 5 times or so.

Thanks for the info. We just picked up a used 2020 xlt and it has the thunk under braking/coasting.

Mine is a 4wd and it some times clunks when shifting to 3rd or 1st while braking.

There’s another thread on here that discusses someone who had a TSB fix for the down shift issue. Needed a new Valve control body. I dont think it matters if its 4wd of 2wd for that issue.

Hi .. sorry for raising the thread again but today I heard the sound, is it something danger to keep? If you fix it, how long does it take to be fixed? Thank you
