5. Cap the U-bolts with four 3/8” flat washers (J) and 4 x 3/8” nylon lock nuts (I) (fig. 1).
Leave loose at this time.
6. In order to make sufficient clearance for the flex member (the rubber part) on the air
spring, it will be necessary to trim the edge of the bracket off on the outside flange
of the jounce bumper cup (steel portion). Do this by grinding the flange flush with
the rest of the cup (figs. 9 and 10). Spray black paint on the bare metal surface once
complete. Repeat for both sides.
7. Insert the M-10 tap bolt (G) through a flat washer (J) and then through the jounce
bumper (fig. 1). Using the center hole in the bottom flange of the upper bracket,
install this assembly back onto the bottom frame flange in the location from which
it was removed, making sure the edge that was ground off faces the outside of the
vehicle (fig. 11). Tighten the bolt so that the bracket just touches the frame at this
time. Do not tighten or torque yet. Repeat for the opposite side.
MAKE ONE LAST CHECK THAT THE U-BOLTS ON THE INSIDE OF THE LEFT FRAME
(DRIVER SIDE) ARE NOT PINCHING THE BRAKE LINES OR THE WIRING. ADJUST IF
NECESSARY AT THIS POINT.
8. With the upper bracket flush to the bottom frame flange from the last step, torque the
frame U-bolts evenly to 10 lb.-ft. (14Nm). Once this is done and the bracket is flush
against the frame, torque the jounce bumper bolt to 30 lb.-ft. (41Nm). Repeat for the
other side.
