CV Axle slop.. I can't convince my mechanic!

went there to align her after Replacing LCAs, for him to discover seal on driver's side is leaking. I've just replaced the seal after ECGS bushing install. That's another story that I didn't get response yet:

He thinks that the slop that's in the shaft (even after the bushing, much less and NO vibes) is the reason why it was leaking, I say I fucked-up the seal install and trying to tell him that slop was there since new and only leaked after I replaced the bushing (145K miles, with new premium axle). Had him do the seal again at a couple of $C$ bills.
I think the new seal is leaking so I'm leaning towards clogged breather... I'll know later

Is it true that all Tacoma FJ etc have driver-side axle slop, or I'm wrong?

 

this is true, many posts about it

 

mine does, but it doesn't leak. 48k. I'm doing the ecgs bushing shortly.

 

Not true, they not all have it. 70000 on mine and its still solid, no slope.
