its hard and messy, you need to take the cv axle out, and what i do is clean it with a scotch pad to get all the outside greese and grime off.

then you demolish the boots and do whatever you can to get the cable ties off

then you take it all apart (this is the messy part) and there are 2 c clips that hold the little thing on lol, you get that off, put the boot on, and re assemble

really dont feel like going in detail.


cliff notes:
just buy new axles.
