Air suspension U-bolt checks and re-torquing procedures
1. Inspect the threads of the U-bolt and nut for rust and debris. Clean
the threads if contaminated.
2. Using a torque wrench, determine if any nuts can be turned with a
force below the specified torque.
3. Using the lowest discovered torqued nut as a starting point, retighten
the nuts using the sequence listed underAir suspension U-bolt and
U-bolt nut installation.
Air suspension U-bolt and U-bolt nut installation
1. Inspect the threads of the U-bolt and nut for rust and debris. Clean
the threads if contaminated.
2. Install the U-bolts and nuts and torque the nuts to 15 ft. lbs. (20
N•m), using a diagonal pattern.
3. Re-torque the nuts to 100 ft. lbs. (136 N•m), using a diagonal pattern.
4. Re-torque the nuts to 200 ft. lbs. (271 N•m), using a diagonal pattern.
5. Re-torque the nuts to 400 ft. lbs. (542 N•m), using a diagonal pattern.
(For vehicles equipped with 14ACC, 14 ADN and 14ADP axles, do not
use Step 6.)
6. Re-torque the nuts to 425 ft. lbs (576 N•m), using a diagonal pattern.
(For vehicles equipped with 14ACC, 14 ADN and 14ADP axles.)
7. Use the same diagonal pattern with each U-bolt nut re-torque.
Spring U-bolt checks
Check U-bolt nuts and re-torque every 36,000 miles (58,000 km) after
initial 1,000 miles (1,600 km) re-torque. The U-bolt and nut threads and
seats should be cleaned and lubricated to assure peak condition when
re-torqued.
PROPELLER SHAFT
At the regular lubrication interval, check the universal joints for any
evidence of wear or looseness. Should propeller shaft vibrations occur,
stop the vehicle immediately to avoid possible hazardous consequences
or damage to other components.
