Detroit New Final Drive Top Performance Axles with Active Lube Management

Detroit has launched its New Final Drive Top Performance axles with the active lube management (ALM)
system. This new axle requires different amounts of oil than previous Detroit axles and standard performance
axles. The oil fill and check-hole location is located on the carrier of the axle, and not on the back of the axle
housing. The new fill location is only on the Detroit New Final Drive Top Performance axles with ALM.

@ Notice: Standard and Top Performance axles use the same axle housing,
however, on Top Performance axles the plug in the back of the center section of the
axle housing is factory-installed from the inside to prevent using it as a check and fill
point. Changing this configuration may lead to improper lubrication of the axle, axle
damage, or loss of performance.

Identifying Detroit Performance Axles
There are two ways to identify with which axle a vehicle is equipped.

1. “Park the vehicle on a level surface, shut down the engine, and apply the parking brake. Chock the tires.

2. Access ServicePro® or Excelerator by VIN to get the correct axle model for the vehicle being serviced.

Table 1 lists the model number designation for standard and top performance axles.
