Add-a-leaf will be placed in the spring as-
sembly progressively according to length. For
example, if the existing leaves are 32” long and
25” long and the add-a-leaf is 28” long, place
the add-a-leaf between the existing leaves.
1. Insert the add-a-leaf (TM3730-60020). Re-
clamp and bolt the leaf pack back together using
the supplied center bolts from pack (90-3856)
with the heads of the bolts facing down and the
nut on the top. When you are finished you may
need to trim the excess thread from the center
bolts, so that it does not hit the U-bolt bracket on
top of the leaf springs. Bend the alignment
clamps back around the leave.
2. Make sure the pins fit into the holes on the
spring perch. Use your floor jack to raise the
axle to the spring making sure the head on the
factory leaf fit into the holes on the spring perch.
3. Secure the assembly with the OE U-bolts and
hardware. Do not tighten the U-bolts at this
time. Make sure the spring sits flush on the axle
perch. If there is a gap grinding down the heads
of the bolts may be necessary.
4. Repeat the installation on the other side of the
vehicle.
5. When the installation of the remaining side is
complete, torque the U-bolts to 95 ft. lbs. If the
threads are too long you can trim the threads.
6. Install the new rear shocks (TM73225010) to the
OE mounting locations.
7. Reinstall the sway bar end links to the rear axle
using the previously removed OE hardware.
8. Reinstall the wheels and tires and lower the ve-
hicle to the ground. Torque according to manu-
facturers specification. If you are using after-
market wheels follow the manufacturers recom-
mended specifications.
9. Recheck the wheel lug torque on all four wheels
at this time.
10. Recheck all hardware for proper installation and
torque at this time.
11. On completion of the installation, have the head-
lights re-aligned.
12. Test drive and note location of steering wheel.
13. Adjust drag link to center steering wheel.
14. Align vehicle as soon as practical to minimum
factory caster and maximum factory toe-in
specifications.
15. After 100 miles recheck for proper torque on all
newly installed hardware.
16. Recheck all hardware for tightness after off road
use.
