NOTE: Torque specifications listed above are with clean
lubricated/coated threads, supplied by SAF-HOLLAND
IMPORTANT: The use of special lubricants with friction
modifiers, such as Anti-Seize or Never-Seez
without written approval from SAF-HOLLAND
Engineering, will void warranty and could
lead to over torquing of fasteners or other
component issues.
General Information
1.
The torque specifications listed throughout the manual
are applied to the nut and NOT the bolt.
IMPORTANT: Most of the fasteners used in this suspension
are Grade 8 bolts and Grade C nuts. These
fasteners have the strength and hardness
properties required for their particular function.
They must be replaced with fasteners of the
same grade, size and form as the original in
order to prevent failure (Figure 62).
Failure to use the proper fasteners when
servicing the suspension could cause
component failure which, if not avoided,
could result in death or serious injury.
Failure to properly torque all fasteners will
result in component failure which, if not
avoided, could result in death or serious injury.
2.
All fasteners MUST be torqued after the first 100 hours of
service or 5,000 miles (8,000 km).
3.
Refer to vehicle OEM for torque specifications for vehicle
frame fastener hardware.
