Driveshaft center support (carrier bearing) question

alright, I know the question has been asked and the bearing has been discussed to no end, but I can't find the answer to the question that is leaving me some doubt. I've got a vibration, worst accelerating 0-30 mph but can be felt under any acceleration. I can't feel it especially when taking tight turns also. It's a vibration similar to when the differential carrier goes bad but I've got good back lash (from a general feel of slop) in the gears. No play or give in all three u joints, and no vertical play in the pinion bearing of the axle or out put bearing of the transfer case. Only play and movement I have in the rear is the amount of slop in the center support bearing of the driveshaft. I'm not too familiar with these bearings as I come from the jeeping community where nothing has them, but from what I've read, they should have some play in them. I think the amount on mine is too much tho. From the look of it roughly from laying under there, my driveshaft is sitting below center of the bearing from the amount of slop in it and I can shake it probably a solid 3/4 of an inch.

FWIW, truck has 135k miles and the vibe also got worse after 2" rear lift install, I've ordered a master rebuild for the rear axle, and if I don't need it, that's fine, it'll go towards the regear/locker install. I've also ordered the carrier bearing for the driveshaft.

 

It shouldnt be sloppy. Id replace it
