- Suspension fasteners must be re-torqued at 6,000 miles and again at 50,000 miles.
- Axle-to-suspension welding must follow Ridewell Weld Process No. 1.
Maintenance Notes
- Daily: inspect tires, wheel ends, axle assemblies, suspension structure, and air system; drain air reservoirs.
- First 6,000 miles: torque suspension components and verify mounting height.
- Every 12,000 miles: inspect air springs, air lines, and fasteners.
- Annually or 100,000 miles: inspect pivot bushings and wear washers; replace as required.
