Output Shaft Sleeve

Hello to all you mopar experts. I have a 833 and for a while now I have had a leak out of the tail shaft seal but have been living with it. I have replaced the seal a few times to no avail. Yesterday I was in a driven line shop getting a new driveshaft made and he told me my slip yoke was no good due to the rear bushing eating up the yoke. I cant seem to find much on replacing the bushing so I thought I would ask here. Is this something you can replace without taking the transmission apart? As always, thanks in advance.
