Dodge Charger 1982-1987 Drivetrain Specifications

The 1982-1987 Dodge Charger typically features a rear-wheel-drive (RWD) system with a live rear axle. Compatible components include the A904 or A727 automatic transmissions, as well as manual options like the A833 4-speed. The rear differential is usually an 8.25-inch or 7.25-inch unit. Ensure compatibility by verifying VIN and engine type, as variations exist between models and years.

Regular maintenance includes checking and replacing transmission fluid every 30,000 miles, inspecting the driveshaft U-joints for wear, and ensuring proper lubrication of the rear differential. Inspect the clutch system (if manual) for wear and adjust as needed. Regularly check for leaks, unusual noises, or vibrations, which may indicate drivetrain issues requiring immediate attention.

To replace the driveshaft, safely lift the vehicle and secure it on jack stands. Remove the bolts connecting the driveshaft to the differential and transmission. Slide the driveshaft out carefully. Install the new driveshaft by aligning it with the transmission and differential flanges, then secure with bolts. Ensure proper balance and alignment to avoid vibrations during operation.

Noises from the drivetrain may indicate worn U-joints, a failing differential, or transmission issues. Inspect the U-joints for play or rust. Check the differential fluid level and condition. For transmission-related noises, verify fluid levels and inspect for leaks. If the issue persists, consult a professional mechanic for a thorough diagnosis.

To optimize performance, upgrade to a limited-slip differential for better traction. Use high-quality synthetic fluids for the transmission and differential. Consider a performance clutch kit for manual models. Ensure proper alignment and balance of the driveshaft. Regularly inspect and maintain all components to prevent wear and ensure smooth operation.
