Experiencing a “shudder” when braking below 20mph, TSB?

Newer truck? Mine did that a bit when it was new. I'm at 20k miles now, and it doesn't do that anymore. I can't recall when it stopped, but I distinctly remember something similar when braking.

 

I have this same shudder/vibration when breaking below 20 MPH took it in to toyota dealership. Service advisor said something in my back end was off 3mm and now they are replacing my whole back end under warranty i will post what the exact thing is when i find my paper work. 2019 with 7k miles

 

Please keep us posted buddy. Thanks

 

Thinking the same. I’m going to drop my shaft another 1/4”. I’ll let you know if it works. Won’t be for a couple weeks

 

Updates?
