Is this something to worry about?

[Thursday7]

So when I reinstalled my transmission and driveshaft a few months ago, I noticed the carrier bearing is able to move up about a half inch if I push hard enough, right where the bracket is. I have to put a considerable amount of force to move it up, and it means moving the trans. with it a tiny bit.

Here is a video I took. Yes, that is my dog breathing in the background

this is coming from the datsun 620 (truck) community, where just about every single 620 owner has their carrier bearing BUSHING/INSULATOR (not the actual bearing itself.) is deteriorated/non existant.

what that will do is allow the driveshafts to clank around inside the insulator housing, but it will smooth out once you get going/up to a certain rpm. this is bad because it will put undue stress/wear on your u-joints, and youll have to replace them sooner.

HOWEVER! your insulator is still there which is whats important. it has a little play, and i dont know what the high tolerance for play is but i would say its good and nothing to worry about.

also, next time try to have the camera more steady so we can actually see how much it is moving :)

lol, yeah, I had to rest the camera on my face because 2 arms were needed to move the driveshaft. But yeah, I found that the upper piece of the driveshaft carrier bracket just isn't there.
