My forks were leaking so I replaced the seals. Rode it a week or so and noticed one side was leaking again. Took it apart tonight and examined the slider tube really good. I found a pretty significant nick in the slider which is where I assume it is leaking and possibly damaging the seal. Is it as easy as ordering another slider tube and installing or is there other parts I would need to order for the slider tube?

 

You should be able to order one from the dealer no problem.
You could try to smooth out the nick and reinstall it in an upward facing position just for grins.
Luckily it's not a really bad job to do , and you already know how .....
