CV Axles replaced, 1 leaking from input shaft

I recently replaced my front cv axles on my tacoma. My driver side cv is good and not leaking. My problem is in my right axle. I replaced this one the same way, and well this one is leaking from the input shaft to the differential extension arm where the metal retainer on the shaft and the rubber seal in the extension met. Has anyone had any problems with this when replacing the cv or am i doing something wrong.

 

it happened the first time i replaced my cv's. the clip on the end tore my seal a bit. i got my seal from the dealership and install it..and then put the cv back in without a problem. it helps to put a little grease on the clip and point the ends of it down when putting a cv in. the seal isnt too bad to replace...just go slow and use something with a smooth flat end. i used a socket on one side...and then a long punch on the other.

 

I just fore warned another member about this when he replaced axles , those inner seals are super soft ,expensive & tear easy as hell

 

My right side axle is leaking in the same spot. But it has alittle sliding where the boot meets the diff. How can i fix
