Jeep Cherokee 1974-1983 Drivetrain Specifications

The 1974-1983 Jeep Cherokee typically features a Dana 30 front axle and a Dana 44 rear axle, with options for manual or automatic transmissions. Common engine options include the AMC 258 inline-6 and the AMC 304 V8. Compatibility depends on the specific model year and trim. Always verify part numbers and specifications before purchasing or installing components.

Regular maintenance includes checking and replacing differential fluid every 30,000 miles, inspecting U-joints and CV joints for wear, and ensuring proper lubrication of the transfer case. Transmission fluid should be changed every 50,000 miles, and the driveshaft should be inspected for balance and alignment. Regular greasing of suspension components is also recommended.

To replace the transfer case, first, disconnect the driveshafts and shift linkage. Support the transmission and transfer case with a jack. Remove the mounting bolts and carefully lower the transfer case. Install the new transfer case by reversing the steps, ensuring proper alignment and torque specifications. Refill with the recommended fluid and test for leaks.

Unusual noises may indicate worn U-joints, failing bearings, or low fluid levels. Inspect the driveshaft for damage and check differential and transfer case fluid levels. Listen for specific sounds like grinding (bearings) or clunking (U-joints). Replace worn components and refill fluids as needed. If the issue persists, consult a professional mechanic.

Upgrade to high-performance U-joints and CV joints for durability. Use synthetic fluids in the differentials and transfer case for better lubrication. Consider a limited-slip differential for improved traction. Regularly inspect and maintain components to prevent wear. Properly balance the driveshaft and ensure alignment to reduce vibrations and improve efficiency.
