CK20HST front axle leak

[Slackdaddy]

My ~2008 CK20 leaks gear oil at the right side "Steering knuckle"
It is a slow leak,, but when it sits a while,, it leaks a good amount.
I have a shop and the tools,, how involved is this? and what are the most likely parts I need to order?
Many thanks,

Keep us posted if you do the work yourself. Mine aren't leaking but hey things happen! I did have a leak on my rear left axle which I dealt with myself. I'm sure like the front it's simply a seal that needs replacing. because I had it apart I replaced the 2 bearings at the same time. Minimal additional cost - actually thinking of I had to pull the bearings to get at the seal so chances are I might have damaged the bearings in the process. (this was a little while ago and my memory isn't great!)
I just took a look a the workshop manual. Not quite as I expected! Lol.
See file if you've not got it already.
