Shudder at take off

https://youtube.com/shorts/_YeUmM642hU?si=zUwnKKMcRGtvGbbd

here’s a video I was able to take from underneath to maybe visually see shudder. Been noticing a shudder from take off (not at higher speeds just from stop to take off). Have thoughts it may be carrier bearing or u joints as I’ve been told by lots of people. Had 1 person say torque converter but it doesn’t do it past take off. What’re you guys thoughts? TIA.

 

Axle wrap from stock leaf springs. "vehicle characteristic"

Put the camera pointed at the rear most u joint, you will shit your pants with how much the pinion angle changes from axle wrap.

 

Okay thank you. I will try this next hopefully that’s it lol

 

When mine started to shudder, it was the rear U joint that was frozen.

 

U joints was another thing suggested mainly that and Carrier bearing .. going to look more into it this weekend

 

Mine shuddered at take off. I dump money into rebalancing the driveshaft and replaced the carrier bearing and it still shuddered. I learned from this site that the transmission fluid can also cause this. I had the dealer flush the transmission fluid and the shudder went away.

 

Thing is I just got it flushed about 15k miles ago

 

I also added “Lube Guard” at the same time.

 

Its normal on lifted trucks Mine does it on take off but I can't feel it in my butt
