It seals the internal piston to prevent air and oil leaks that can cause the locking mechanism to fail. Replacement is typically needed when the differential lock becomes sluggish, fails to engage, or when rebuilding the lockout cylinder. Dana has updated the design to a more durable fluoroelastomer (FKM) material under part number 210180-A.
