trol, which could result in property damage, seri-
ous personal injury, or death. Vehicles with
cracked or missing restrictor cans may be driven
slowly to the nearest workshop for restrictor can

Reyco 79KB Suspension Visual
Inspection
The Reyco 79KB suspension requires minimal main-
tenance. To provide trouble-free operation in over-
the-road applications, do the following inspection.
1. Park the vehicle on level ground. Apply the park-
ing brakes, and chock the tires.
2. Check that the torque rod clamps are directed
away from the spring to prevent possible interfer-
ence during operation. See
Fig. 9 .
3. Check the fit of springs to hangers to ensure
good ride characteristics.
4. Check for elongated holes in the suspension
components. See Group 32 of the
Acterra ®
Workshop Manual for proper repair procedures.
5. Check bushing condition. Replace any bushing
that is worn, cracked, dry-rotted, or otherwise
damaged. See Group 32 of the
Acterra ® Work-
shop Manual for removal and installation instruc-
tions.
6. Check tire condition. If abnormal tire wear is
found, check and replace all worn or damaged
components, and check suspension alignment.
See Group 32 of the
Acterra ® Workshop Manual
for component removal and installation proce-
dures, and for suspension alignment instructions.
Reyco 79KB Fastener Torque
Check
Check the U-bolt nuts, hanger mounting bolts, torque
rod clamp nuts, and the spring retainer bolts for
proper fastener torque.
1. Park the vehicle on level ground. Apply the park-
ing brakes, and chock the tires.
