Symptoms of bad differentiation bushings

Hello, I'm trying to figure out where the weird grinding/clunking is coming from when I accelerate. Its only happening when I accelerate and is worse the more aggressive I leave from a dead stop. It is much less when I am accelerating normally but it's still there. It definitely feels like lots coming from the rear differential area. Does this sound like it could be the bushings? Possibly u-joints?

Sounds like a carrier bearing, I would check that first. Less costly and way easier to repair.

Thats one of the possibilities I was thinking about but, wouldn't I feel/hear it when the car decelerates?
