Here is what to do if you don't want to cut anything.
A: remove the nut so that the top of the joint is free.
B: loosen these two nuts and unscrew until they are touching the "nut" in the middle of the two.
C: screw these further into the thread (basically screw them so that they get closer to the middle where the nuts are).
Eventually you won't be able to turn them any further. Once they are as close as they will go, back the "B" nuts back into them to lock them in place.

Hope that makes sense. There are three of these to adjust. One under each front wheel well and one in the rear.
