Questions: The steering knuckle has a threaded port for adding fluid for lubrication, it is not mentioned on your site. What is used for this, and what prevents it from leaking/ seeping out of the lower king pin? The king pin does not have a seal to prevent leaks.

The housing of your knuckle as a fill plug. You just fill till it pours out. Alittle sealant on your bottom king pin caps will do the trick.

Questions: There is a odd shaped piece of steel (rain gutter?) that bolts to the top of this. The front wheel brake line also attaches to this. Any thoughts?
