Question: Do shaft seals on trans and cv boots need to be changed?

If the seals are leaking they have failed and should be replaced. No the cv boots dont need to be replaced unless they too have ruptured. There are 4 cv boots and it is doubtful that they are all bad but possible. I would get a second opinion if some recommended all cv boots to be replaced. I have only replaced 1 or 2 on vehicles at a time but never all 4.
