On-Highway Applications -
Standard
• Pressure lubricate every 6 months
or 25,000 miles (40,000 km).
• A more frequent lubrication cycle is
required for axles used in on/off-
highway, refuse, or other severe
service applications. Use heavy-
duty, multipurpose lithium base (#2
grade) grease.
NOTE
DO NOT mix with sodium-based
grease.
