Le AZ9970320260 Rear Axle Center Housing (often referred to as the Middle Section or Differential Carrier Housing) is the structural core of the Sinotruk HOWO heavy-duty drive axle. Engineered specifically for the HC16 and AC16 axle series, this housing protects the differential assembly and ring-and-pinion gears while supporting the immense torque required for mining and long-haul operations.

Note: The rear axle center housing is a precision component. Incorrect installation can lead to oil leaks or gear whine.
-
Cleanliness is Priority: Before mounting the AZ9970320260, ensure the axle housing faces are completely clean of old gasket material or silicone. Any debris will cause misalignment.
-
Inspect the Internal Bore: Check the bearing seats inside the housing for any burrs or transport damage.
-
Sealing: We recommend using high-quality liquid gasket (anaerobic sealant) rather than paper gaskets for a better seal against the heavy vibrations of HOWO trucks.
-
Torque Sequence: When bolting the center housing to the axle tube, use a criss-cross pattern. Torque the bolts to Sinotruk's specified 240-280 Nm (verify against your specific service manual).
-
Lubrication: After assembly, refill with 85W-90 or 80W-140 heavy-duty gear oil. Ensure the breather valve on top of the housing is clear to prevent pressure buildup and seal leaks.
