4510 steering knuckle seperation

[ktm250rider]

I need to replace a seal on the front end of my 4510. Its leaking between the shoulder housing and the steering knuckle. I cant quite figure out how to seperate the two. Do I have to take the whole thing apart? Looking at JDparts it looks like I may have to take the bottom of the knuckle apart to get the housing apart. Anyone have any info or suggestions?

Yup, had to take the whole thing apart to get the pieces seperated. Oh, apparently, the units are filed with oil. Some bozo seperated the knuckle from the tractor with out having a bucket handy. Good thing the garage floor caught it all.
Now to find a bearing and seal.
