Comments about MOOG Ball Joint:

On a side by side comparison, the Moog unit looks beefier with a larger socket area. Exact fit with no install issues. Comes with an angled grease fitting which is GOOD but I replaced it with an "L" fitting since my grease gun doesn't have a flex hose. The price is considerably higher but with the gusher bearing design, it is an upgrade from OEM unit. Hopefully this one will be the last one I need since the OEM lasted 20 years. I do use this truck off-road and I wanted the best available. Moog's reputation was a major selling point.

      For screw in type, a 15" adjustable wrench will work. It just needs to open to 2 1/16". You will get more uses out of the adjustable than you will get from a huge and expensive socket. 14" pipe wrench will work also, but takes a little extra patience.
