Front End Installation:

1. To begin installation, block the rear tires of the vehicle
so that the vehicle is stable and can’t roll backwards.
Safely lift the front of the vehicle and support the frame
with jack stands. Place a jack stand on both the driver
and passenger side. Next, remove the wheels and tires
from both sides.

2. Working on the driver side, remove the stock shock
from the stock upper and lower mounting point and save
the stock hardware for later re-installation. The stock
shock may be discarded.

Special Note: New longer
front shocks are needed after the completion of the
installation. If you have not already ordered your
front shocks, and the vehicle that you are working
on was manufactured from 1980-1987 please contact
Tuff Country or your local Tuff Country dealer and
order part # 61262. If the vehicle that you are working
on was manufactured from 1988-1996 please contact
Tuff Country or your local Tuff Country dealer and
order part # 61261. Repeat procedure on the passenger

side.

3. Working on the driver side, remove the stock castle
nut and cotter pin that connects the stock pitman arm to

the stock drag link. Save the stock castle nut and cotter
pin for later re-installation. Carefully break the taper on
the stock drag link and stock pitman. Special Note:

Take special care not to rip or tear the dust boot on
the stock drag link.

Next, remove the stock nut and
washer that connect the stock pitman arm to the stock
sector shaft. Save the stock nut and washer for later re­installation. Using a pitman arm puller, carefully remove
the stock pitman arm from the sector shaft on the stock
steering box. A new pitman arm is needed, the stock
pitman arm may be discarded. Special Note: The new

pitman arm is sold as a separate part number. If you
have not already ordered your new pitman arm,
please contact Tuff Country or your local Tuff
Country dealer and order (1) 70200.

See Illustration # 1

Special Note: If the vehicle that you are working on
is not equipped with a stock front sway bar, please
skip to step # 5

4. Working on the driver side, disconnect the stock sway
bar from the stock frame mount and save the stock
hardware for later re-installation. Repeat procedure on
the passenger side.

5. Place a pair of hydraulic floor jacks under the front
twin “I” beam axle.

6. Working on the driver side, remove the stock U-bolts
from the stock location. The stock U-bolts and hardware
may be discarded. Place the stock upper and lower U­bolt plates a side for later re-installation.

7. Working on the stock front twin “I” beam axle pivot
drop bracket, remove the stock bolt that connects the
stock front twin “I” beam axle to the stock front twin “I”
beam axle pivot drop bracket and discard the stock
hardware.

8. Carefully lower down on the hydraulic floor jacks that
are supporting the front twin “I” beam axle approximately
5”.

Special Note: Take special care not to kink or

over extend any brake lines and or hoses. This will

allow enough room for the new front springs and new
front twin “I” beam axle pivot drop bracket to be installed
into the stock location.

9. Next, remove the stock front twin “I” beam axle pivot
drop bracket from the stock location and discard the
stock front twin “I” beam axle pivot drop bracket and
hardware.

10. Working on the driver side, remove the stock spring
from the stock location. The stock spring may be
discarded. Save the stock spring eye hardware for later
re-installation.

bushings, (1) S10008 front spring eye shackle sleeve

and (1) polyurethane lube pack. Working on the driver
side, remove the stock front spring shackle from the
stock frame mount and save the stock hardware for later
re-installation. Carefully press out the stock bushing and
sleeve from the stock spring shackle and discard the
stock bushing and sleeve. Install the new bushings and
sleeve into the stock front spring eye shackle. Special

Note: Make sure to use the new polyurethane lube
pack prior to inserting the new bushings back into
the new front spring shackle. This will increase the
life of the bushing, prevent squeaking and help with
ride quality.

Install the stock front spring eye shackle
back into the stock location using the stock hardware
that was removed earlier in this step. Make sure to use

thread locker or locktite on this bolt. Do not tighten
at this point.

See Illustration # 2

12. Locate (1) new front leaf spring. Working on the front
and rear eyelet’s of the new front leaf spring, remove the
new sleeves and bushings from each end of the new
front spring and set a side for later re-installation.

13. Locate (1) new polyurethane lube pack. Spread the
new polyurethane over the new bushings that were
removed from step # 12 and re-install them back into the
new front spring assembly. Re-install the new sleeves
back into the previously installed bushings.

Special
Note: Make sure to use the new polyurethane lube
packs prior to inserting the new bushings back into
the new front springs. This will increase the life of
the bushing, prevent squeaking and help with ride
quality.

14. Working on the driver side, install the new front
spring back into the stock location and secure using the
stock hardware that was removed from step # 10.

Special Note: The new front spring has an off-set
centering bolt, the shorter end of the spring needs to
be installed towards the front of the vehicle. Make
sure to use thread locker or locktite on these bolts.

1/2” bolts and hardware. Make sure to use thread

locker or locktite on these bolts. Special Note: Due
