833 rear bushing replace

I have a vibration that felt like the drive shaft. Investigation showed me some respectable play up and down on the yoke bushing. Enough for me to make a tapping noise pushing up and down when it stops. So I figure it needs replacing. After reading this thread I thought if a shop had the tool it might not cost that much for them to replace it. So far no one has the tool. One guy said he go rid of all his manual trans tools. May have to do it myself. Question, can it be pulled out using a slide hammer without removing the trans? I used the slide hammer to take out the seal which I know is easier to pull. The puller looks like it pushes against the output shaft to pull the bushing. Using a slide hammer wouldn't put any forces on the internal trans parts. I assume when they made the tool they verified the forces wouldn't hurt anything but if you could do it without putting the pulling force on the shaft it sounds better to me.

So how much play is normal or too much? I should figure out if the play is normal which means it could be something with the rebuilt drive shaft. Anyone know how to determine if the play is normal or excessive? Does this look like too much play in video: 20161106_142152.mp4

I did find a place that has the tool and said it would be $150-$175 to change it. If does need to be replace it would be cheaper to have them do it but it's a 20 mile drive with loose bushing.
