I bought my 2019 Bullitt last year with around 3600 miles on it. After driving it for the year and installing the Ford Performance Magride handling kit and steeda's subframe support bushings it decided to go and eat it's rear differential bushings. I had this same issue in my 2015 GT but at around 90k miles (with similar mods) not the 15k miles my Bullitt has.
My GT had Poly bushings from Energy suspension and while they performed great they transferred a massive amount of NVH from the back of the car. ( I assume my one peice aluminum driveshaft didn't help)
While researching parts to fix my Bullitt I came across these
https://www.kelltrac.com/S550-S650-Mustang-Differential-Bushing-Upgrade-Kit-RUBBER_p_112.html
They're a bit pricey but they're pretty amazing! the car performs much better now, the rear end is much more planted and there's less slop when accelerating and decelerating, there's also a very slight improvement in shift feel. There is slight gear whine / howl from the rear in 6th gear at around 65mph but it's nothing terrible and can probably be fixed with a little sound deadening in the trunk..or just turn up the radio.
Just wanted to get these out there because I haven't seen another set of replacement rubber bushings for the Mustang. Before purchasing them I called up the store expecting to get a regular help line but instead I got the owner and designer of the part who answered all of my questions, so customer service is great.
Here's a picture of the torn bushing
