Can the oil pan be removed on 2002 Ford Explorer 4.6 XLT without pulling engine?

Generally, no. On a 2002 Ford Explorer 4.6L, removing the oil pan typically requires at least significant lowering of the engine, if not complete removal. There's just not enough clearance to get the pan out from underneath with the engine fully in place. While some extraordinarily skilled mechanics *might* find a way to do it without completely removing the engine, it's extremely difficult and not recommended. The risk of damaging other components far outweighs the time saved.
