31. Locate the driver side rear differential relocation brack-
et and the short stock mounting hardware. Also, locate (1)
1.750” x .563” x .593” spacer sleeve from hardware bag
56070NB1. Install the new bracket using the stock hard-
ware into the stock rear mounting location. Special note:
We want to make sure and install the spacer sleeve
between the new bracket and the stock differential.
Also, we want to make sure that the “L” side of the
bracket is towards the inside of the vehicle. For now,
just get the stock bolt hand tight.
32. Locate the new front cross member. Locate (2) 7/8” x 5
1/2” bolts, (4) 7/8” flat washers and (2) 7/8” unitorque nuts
from hardware bag # 3 in hardware box 56070NB. Install
the new front cross member into the stock front lower con-
trol arm pockets and secure using the new 7/8” x 5 1/2”
bolts and hardware. Do not tighten at this point. Special
note: When we install the front cross member make
sure that the Tuff Country Logo is facing forward.
33. Locate the new rear cross member. Locate (2) 18 mm
x 165 mm bolts, (4) 18 mm flat washers and (2) 18 mm uni-

stock front lower control arm pockets and secure using the
18 mm x 165 mm bolt, hardware and slot washers. Do not
tighten at this point. Special note: Make sure that the
new slot washers seat properly into the stock cam

18 mm bolts are torqued to specs. The new 18 mm flat
washer will fit towards the head of the bolt and towards
the new unitorque nut.
