What is your question?
Nnot aure what socket will work on the plugs. The recomended size and other sizes do not grip.
How long has your 2006 Mercury Mountaineer had this problem?
A couple of days

if it's a 4.6L,then it takes a 9/16 socket. Spark plugs are torqued to the proper specification. Spark plugs- SP-546 and SP-547 require properly torqued to 30-38Nm (22 to 28 Ft. lbs.) with a dedicated 9/16†spark plug socket; Gap: .045; w/ Black Coil Boots.
It takes either a 5/8 ‘spark plug’ socket - OR - a 9/16 ‘spark plug socket’..
