into the stock location. Set the stock lower control arm,
front and rear mounting hardware aside. Repeat procedure
on the passenger side.
17. Place a hydraulic floor jack under the front differential
and carefully raise up on the hydraulic floor jack until it
makes contact with the front differential.
18. Working on the driver side, remove the stock rear
mounting hardware that connects the stock rear bracket to
the rear portion of the front differential and the rear driver
side stock lower control arm pocket. We want to save the
shorter of the two stock bolts. The longer stock bolt and
bracket may be discarded.
19. Working on the back side of the stock rear cross mem-
ber, measure from the center of the of the stock lower con-
trol arm mounting location to the the inside of the vehicle 2
1/2” and scribe a mark. Repeat procedure on the passen-
ger side. Using a sawzall, carefully cut the rear cross mem-
ber out of the stock location. Follow the lines that were
scribed on the driver and passenger side of the stock rear
cross member and also make sure to cut all the way
through the rear cross member. The stock rear cross mem-
ber may be discarded. Special note: Tuff Country does
not recommend using a torch when making these cuts
on the rear cross member.
20. Now that the rear cross member has been removed,
clean, dress up and paint any exposed metal.
21. Place a hydraulic floor jack under the front drive line
and carefully raise up on the hydraulic floor jack until it
makes contact with the front drive line.
22. Working on the driver side, remove the stock front
mounting hardware that connects the stock front differential
bracket to the front cross member. The stock hardware
may be discarded. Repeat procedure on the passenger
side.
23. Carefully lower down at the same time on both
hydraulic floor jacks holding the stock front differential and
the stock front drive line about 6”. Take special care not to
damage the 4WD wire harness when lowering the front
differential.
24. Working on the driver side, remove the (3) stock bolts
that connect the stock driver side differential relocation
bracket to the stock front differential. Save the stock hard-
ware. The stock bracket may be discarded.
25. Working on the passenger side, remove the (2) stock
bolts that connect the stock passenger side differential relo-
cation bracket to the stock front differential. The stock hard-
ware and stock bracket may be discarded.
26. Locate the new driver side differential relocation brack-
et. Also, locate (2) PB2408 poly bushings and (1) .875” x
.563” x 2.080 crush sleeve from hardware bag 56070NB1.
Install the new bushings and sleeve into the new driver side
differential relocation bracket. Make sure to use a lithium
or moly base grease on the new bushings and sleeve
before installing them into the new bracket. This will
increase the life of the bushing as well as help prevent
squeaking. Set the new bracket aside.
27. Locate the driver side rear differential relocation brack-
et. Also, locate (2) PB2408 poly bushings and (1) .875” x
.563” x 2.080 crush sleeve from hardware bag 56070NB1.
Install the new bushings and sleeve into the new driver side
rear differential relocation bracket. Make sure to use a
lithium or moly base grease on the new bushings and
sleeve before installing them into the new bracket. This
will increase the life of the bushing as well as help pre-
vent squeaking. Set the new bracket aside.
28. Locate the new passenger side differential relocation
bracket. Also, locate (4) PB2408 poly bushings and (2)
.875” x .563” x 2.080 crush sleeve from hardware bag
56070NB1. Install the new bushings and sleeves into the
new passenger side differential relocation bracket. Make
sure to use a lithium or moly base grease on the new
bushings and sleeves before installing them into the
new bracket. This will increase the life of the bushing
as well as help prevent squeaking. Set the new bracket
aside.
29. Locate the new driver side front differential relocation
bracket and the stock hardware. Also, locate (3) 9/16” u-
bolt harden washers from hardware bag # 1 in the hard-
ware box 56070NB. Install the new front driver side differn-
tial relocation bracket to the stock location and secure
using the stock hardware and the new 9/16” u-bolt harden
washers. Special note: The new 9/16” u-bolt harden
washers need to be installed between the new bracket
and the differential. For now, just get the (3) stock bolts
hand tight.
30. Locate the new passenger side front differential reloca-
tion bracket. Locate (2) 9/16” x 2 1/4” bolts, (4) 1/2” USS flat

en washers from hardware bag # 1 in hardware box
56070NB. Install the new front passenger side differential
relocation bracket to the inside of the stock passenger side
differential mounting location. Secure using the new 9/16”
x 2 1/4” bolts and hardware. Special note: We want to
install the new bolt from the passenger side of the vehi-
cle towards the driver and also we want to make sure
that we install the new 9/16” u-bolt harden washers
