Vibrations under drivers side

Hey guys I’ve been looking around the forums for some vibrations I’m getting, I just got them a couple days ago it got really bad today since when I was coming to a complete stop the truck started to vibrate slightly, same with letting off the gas around 50 mph the truck would sound like it’s engine braking. I have swapped out wheel bearing, tranny fluid, and my tires are always rotated and balanced so I’m starting to think it’s the carrier bearing. There’s no play on the driveshaft also. If anyone wants to confirm that it could be the culprit that would be great I’m gonna go buy a new carrier branding just to test it out, thanks for any help/advice!

 

While you ae in it check the universal joints. It sounds like classic u joints / carrier bering problem to me.

 

Awesome yea I just ordered a spicer carrier and u joints, can’t figure any other possibility since I have a 2wd and my differential is pretty new

 

How are the motor mounts?

 

Motor mounts I haven’t checked but I should switch out soon, I don’t think it’s them though since the vibration happens right under my seat
