Hey guys, there seems to be a sound coming from the rear of my transmission, where it connects to the driveshaft. The noise only occurs when I’m gear, and is present both when moving and when not moving. It kind of sounds like a bolt rattling around in a can. I got under the truck and felt the driveshaft, and i can jiggle it around, I’ve heard there’s not supposed to be any play, and that there might be a bearing I need to replace. I’m not very knowledgeable about transmissions, so if yall could lead me in the right direction that would be great. Thank you!
