26. Working on the passenger side, remove the (2) stock
bolts that connect the stock rear cross member to the pas-
senger side rear lower control arm mounting point. The (2)
stock bolts may be discarded. Working on the driver side,
remove the (2) stock bolts holding the rear cross member
to the bracket that is welded to the rear lower control arm
pocket. The (2) stock bolts and the stock rear cross mem-
ber may be discarded.
27. Working on the driver side, measure 2 1/8” towards the
inside of the vehicle from the stock rear lower control arm
mounting point, scribe a mark on the rear cross member.
Using a hacksaw or suitable cutting tool, carefully cut off
the rear cross member along the line that was scribed ear-
lier in this step. The rear cross member may be discarded.
Special note: When making this cut, make sure that
you cut all the way through the stock rear lower control
arm mounting point. If this cut is not performed prop-
erly, the front differential will not seat properly when
the front differential is lowered into the new Sub frame.
Also, at this time, cut the rest of the stock bracket off the
rear lower control arm pocket. Take special care not to cut
into the rear lower control arm pocket. Special note: Tuff
Country EZ-Ride highly recommends not using a
cutting torch when performing step. Clean and dress
up any exposed metal.
28. Remove the front drive line from the front differential.
Carefully tie the front drive line up and out of the way. Save
the stock hardware for later re-installation.
29. Working on the passenger side of the front differential,
locate the wiring harness that connects the 4WD control
panel to the front differential. Disconnect the 4WD wiring
harness from the front differential. Tie the 4WD wiring har-
ness up and out of the way. Special Note: Take special
care not to kink wiring. Also, disconnect the 4WD wire
harness from any other attaching points of the front
differential.
