I finally found the time to overhaul the pump by replacing all the seals. I've traced the shaft bearing, I obviously recommend replacing it if your car has 360,000+ miles like the Honda Pilot 05, but that's up to you. I didn't give 5 stars because the gasket kit DOES NOT include a rubber o-ring for the high pressure line. I had to buy separately. I ended up buying from a local Honda dealer. All in all I only spent about $18 for the bearing, $2.50 for the extra o-ring and $30 for this repair kit and the pump runs like new.
