I'm sure it's just like the 4.0L and it does have to come off. I use a 14MM L-wrench like the link below:

You can put something in the end of it to get a little more leverage and since you don't have to much of a swing, you'll have to take a lot of short turns to get the bolt out. Eventually, you'll run out of clearance for the L-wrench, so you'll have to switch to a stubby, 14MM, combination wrench to get the bolt all the way out. Be careful nut to cross-thread the bolts when re-installing.
