towing GMC SIERRA 1995 Owner's Manual

What to Use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants”
in the Index.
C3 (3500 H.D.) Trucks Equipped with Dana Rear Axle
Additional rear axle scheduled maintenance is required on 3500 H.D.
models equipped with Dana rear axles when they are driven under the
following conditions:
0 Extreme loading (at or near GVWR) or trailer towing, and:
Operation above 45 mph for extended periods of time
Vehicles used
in any of these conditions require the rear axle lubricant (SAE
8OW-90 - GL-5) be changed every 3 months or 3,000 miles, whichever
comes first.
To reduce required maintenance, SAE 75W-140 synthetic gear lubricant
may be used. With the use of synthetic
SAE 75W-140 lubricant, the fluid
change intervals may be increased to 30,000 miles. Before using SAE
75W-140, it is important to drain and flush the axle with clean mineral
based (non-synthetic) axle lubricant. Fluid capacity is 4.12 qts. (3.9L).
Four- Wheel Drive
Most lubricant checks in this section also apply to four-wheel-drive
vehicles. However, they have two additional systems that need lubrication.
Transfer Case
When to Check Lubricant
Refer to the Maintenance Schedule to determine how often to check the
lubricant. See “Periodic Maintenance Inspections”
in the Index.
