SUBJECT:
INFORMATION ON DRIVE AXLE SERVICE
MODELS:
1992-93 C3 (3500 H.D.) TRUCKS EQUIPPED WITH DANA REAR AXLE
Additional rear axle scheduled maintenance is required on 1992-93, 3500 H.D. models equipped with Dana rear axles (Figure 1) when they are driven
under the following conditions:
-
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 driving conditions require the rear axle lubricant (SAE 80W-90 - GL-5) be changed every 3 months or 3,000 miles,
whichever comes first.
To reduce required maintenance, SAE 75W-140 synthetic lubricant (P/N 12346140) may be used. If synthetic SAE 75W-140 lubricant is used, the fluid
change intervals may be increased to 30,000 miles. Before installing, it is important to drain and flush the axle with clean mineral based (non-synthetic)
axle lubricant. Dana rear axle fluid capacity is 3.9L (4.12 qts).
