Mercedes W460 Parts & G-Class Catalogue

The Mercedes-Benz W460 (G-Class) is a rugged and durable vehicle, but due to its off-road capabilities and age, certain parts tend to wear out faster. Here are the most commonly worn-out parts on the W460, especially as the vehicle accumulates mileage and undergoes tough off-road use:

1. Suspension Components

• Shock Absorbers and Struts: The shocks absorb rough terrain impacts, and over time, especially with off-road driving, they can lose their ability to dampen effectively, leading to a bouncy or unstable ride.
• Bushings and Control Arms: Suspension bushings, particularly those made of rubber, wear out over time, especially if exposed to moisture, dirt, and heavy usage. Control arms may also become damaged, leading to poor alignment or handling.
• Coil Springs: Coil springs can sag or lose their tension over time, especially under heavy load or in off-road conditions, reducing the vehicle's ride height and comfort.

2. Brake System Components

• Brake Pads and Rotors: Brakes are one of the most frequently replaced parts due to constant use. Off-roading and driving in tough conditions can wear down brake pads and rotors more quickly.
• Brake Lines and Hoses: Over time, brake lines can corrode or crack, especially in harsh environments. Leaks or damage can cause brake fluid loss and reduced braking performance.
• Master Cylinder and Brake Booster: The brake master cylinder, which controls brake fluid pressure, and the brake booster, which helps with braking force, can fail over time due to wear or moisture intrusion.

3. Steering Components

• Steering Box and Linkages: The steering box can wear out, especially if the vehicle is frequently driven in tough conditions. Worn linkages or tie rods can lead to poor steering response or even dangerous handling.
• Power Steering Pump: Over time, the power steering pump can become noisy or fail due to fluid leaks or internal wear.

4. Drivetrain Parts

• CV Joints and Axles: The Constant Velocity (CV) joints and axle shafts are crucial for transmitting power to the wheels, especially in a 4WD vehicle. Off-roading can put a lot of strain on these parts, leading to premature wear or breakage.
• Differential Seals and Bearings: The differentials are subjected to heavy loads, especially when 4WD is engaged. Seals can deteriorate, and bearings can wear out, leading to leaks, excessive noise, or drivetrain damage.
• Transfer Case: The transfer case, responsible for distributing power to both the front and rear axles, can develop issues, particularly the seals or internal components, due to heavy use of the 4WD system.

5. Engine Components

• Timing Chain and Tensioners: Over time, the timing chain can stretch or wear out, causing misalignment. The tensioners and guides can also wear out and require replacement to maintain proper engine timing.
• Oil Leaks: Common engine wear issues include oil pan, valve cover, and rear main seal leaks, which can lead to oil loss and engine damage if not addressed.
• Radiator and Cooling Hoses: Cooling systems are critical, especially for off-road vehicles. Radiators, hoses, and water pumps can wear out, causing leaks or overheating if not regularly checked.

6. Exhaust System

• Exhaust Manifold and Mufflers: Off-road driving can lead to cracked exhaust manifolds or holes in mufflers due to exposure to rough terrain, heat, and moisture. These can lead to exhaust leaks and reduced engine performance.
• Catalytic Converter: Although generally durable, the catalytic converter can become clogged or damaged over time, leading to poor engine performance and potential emissions issues.

7. Transmission and Clutch (for Manual Models)

• Clutch Disc and Pressure Plate: In manual transmission models, the clutch system is one of the first parts to wear, especially under heavy usage and off-road conditions.
• Transmission Mounts and Seals: Transmission mounts can wear out over time, causing vibrations and poor shifting. Seals around the transmission may leak fluid as they age.
