**NOTE:
WHEN TORQUING THE CRADLE BOLT, ENSURE THE TAPPING PLATE INSIDE THE FRAME RAIL DOES NOT ROTATE AND COME INTO CONTACT WITH THE WALL OF THE FRAME RAIL OTHERWISE ANOTHER NOISE SOURCE WILL BE CREATED.
4. Torque the rear attaching bolt to 163 Nm (120 ft. lbs.)

6. Inspect the front brake hose brackets (right and left), if there is less than 6 mm (1/4 in.) clearance between the brackets and the frame rail, bend the bracket so a 6 mm (1/4 in.) clearance is obtained at each bracket.
