If the OP stated what year his 4runner is, I missed it.
But for example, looking at the 2012 4runner manual, it states on page 299, "If using a weight distributing hitch when towing, return the front axle to the same weight as before the trailer connection."
....so you are correct mister Speak, some of the specs change fron year to year.

True! My own 4runner model says owner can use WD if we intend to tow above the recommended limits. Did not mention the new max though.
