The dealer told me the same thing that the Thud and the driveline noise is normal for MT82... Since it's still under warranty let's how it goes..

I am going to get the diff bushing and see how it goes

That did not fix mine. YMMV.

Still wanna give it a try

Oh, I love mine. Just didn't want someone to have to go out and get it to specifically fix this problem. It's a great mod!

Yep. I agree with you on this one. Going to eliminate some wheel hop and hoping will reduce the thud

Did not fix my either

It may be that our diffs have a fair amount of gear lash. I would interested to see if anyone has compared clearances on their gears to factory specs. Or, do these Torsen diffs have a looser spec?

The main reason I did the diff bushings was for more stability and it did that for me. Tightened things up a bit.

Dealer checked mine against spec and said I had 75% of the the max allowable lash. They don't deny the thud or that it is unusual for most cars. They just said it's normal for this particular car - no problem here....

My thud is now gone. I can only assume it was the driveshaft.

These are all my drivetrain related mods/fluids. The nice thing is that they were all done over time so I definitely think it was the driveshaft. What I bolded is what was the last install, with what I assume fixed it was the driveshaft. I have a PP with the stock 3.73 rear end with the Torsen.

Steeda Tri-Ax
DSS Aluminum Driveshaft
UPR Driveshaft Safety Loop
McLeod RXT
McLeod Steel Flywheel
DSS 1400HP Halfshafts
RP Synchromax
AMSOIL Severe Gear 75W-90
Steeda IRS Subframe Bushings
Steeda IRS Subframe Alignment kit
Steeda Differential Race Aluminum Bushings

Out of the three bolded, I would think the driveshaft. Some people have talked about having some rotational play in their's which makes sense to me. Could be a combo of things, a tolerance stack up of several drivetrain parts.

Have a 3-week 2017 ecoboost that does this. Normally hear the thud when putting it into 1st gear.

I have a 15 GT PP with 5k on it and I have the thud. Thank god I don't have the vibration issue so many others have......

My thud is damn beer gone with Steeda engine mounts. You mileage may vary.

Let's get those Ponies running smooth, Tele5.0, MustangDirector, and Mangrove Mafia.

Checking in with your dealer is a great first step; let me know when you do so.

Also, as I'm seeing this is more than an isolated case, I want to document your product feedback. If interested, please send me your VINs and any additional details about the noise you are hearing while shifting.

It's definitely more than "more than an isolated case", it's ubiquitous.

Been through the dealer - they know all about it. Ford says 'nothing to fix' so their hands are tied. We finally agreed that they'd fix it under warranty when the weak link snapped. It's not news to the dealer so it's not news to the factory. At 9k miles it's still there but I guess I'm more used to it now.
