Rear Axle Fluid:
Hypoid gear oil, typically SAE 90 EP (Extreme Pressure). Capacity depends on the axle type, usually around 3-4 pints (1.4-1.9 liters).
Common Wear Items:
Rust (particularly in wheel arches, sills, and around windows), aging rubber components (bushings, hoses), electrical contact issues, carburetor wear, and potential overheating in V8s under heavy load.
Engine Specific Issues:
Potential for core plug leaks, carburetor tuning issues, distributor wear. V8 engines might require more frequent oil changes and cooling system maintenance.
Brake System Wear:
Brake hoses and seals can degrade over time. Disc pads and shoes require regular inspection and replacement. Wheel cylinders and master cylinders are common wear items.
Electrical System Aging:
Wiring looms can become brittle, alternator/generator brushes wear, and voltage regulators can fail. Grounding points are crucial for reliable operation.
