I figured while I'm this far along, I probably should replace any additional seals to minimize chance for oil intrusion onto steering clutches. I've removed the bolt that holds the inner coupling assembly to try an access the seal near the ring & pinion compartment. Do I need to use a puller to remove the hub assembly to change out seal 3B8188? Attached image should help what advice I'm after if my verbiage is not clear.
 
Thanks 

Sorry for all the extra text, first time uploading images.
