Can any one tell me if there is a timeing chain on the front and rear of a certain model explorer? and how difficult it it to replace

 

The models the have a double overhead cam have dual timing chains. The rear is almoast impossible to access. This is no job for a novice. You may also need a special too for this. Research carefully and make sure you are in no hurry to finish.
Good Luck
