2. REMOVE FACTORY SPRING
MOUNTS FROM AXLE
Inspect the factory spring mount on the axle
housing. Locate the areas that are welded to
the axle tube.
Cut the factory spring mount off of the axle
housing. Use care to avoid cutting into the axle
tube. HINT: A die grinder with cut-off wheel is
useful for cutting off the factory spring mount.
Remove any remaining spring mount material
from the axle housing until surface of axle tube
is smooth. HINT: A grinding wheel is useful for
removing remaining spring mount material.
Locate the long factory weld on front (driver
side) of rear axle tube.
On outboard side (closest to tire) of weld, grind
off 2" of material until smooth and flush with
surrounding area.
With the factory spring mounts removed and the
long factory weld shortened, paint bare metal
on axle tube to prevent corrosion.
