Parts for the Mercedes-Benz G-Class 300 GE

Known issues

Common issues with the G-Class often revolve around wear and tear associated with off-road use. Rust, particularly around the sills, wheel arches, and chassis, is a primary concern. Suspension components, such as springs, shocks, and bushings, can wear out due to the strain of off-road driving. Drivetrain issues, including transfer case problems and axle wear, can also occur. The electrical systems, though robust, are complex and can suffer from corrosion and wiring faults.

WOF tips

WOF (Warrant of Fitness) inspections will focus on structural integrity, particularly rust affecting the chassis and suspension mounting points. Brake performance is critical, given the vehicle's weight and off-road capabilities. Suspension components, steering linkages, and headlight alignment are also scrutinized. Pay close attention to the condition of tires, ensuring they meet legal requirements and are appropriate for off-road use. Any modifications must be certified. Check for excessive play in steering and wheel bearings.

About the Mercedes-Benz G-Class 300 GE

The G-Class is built to last, boasting a rugged ladder-frame chassis and full-time four-wheel drive, but it does have a few common areas that need attention. Suspension components, including shocks and bushings, can wear out from off-road adventures, while braking systems might require routine service to maintain optimal performance. Owners should also keep an eye on electrical systems, which, although robust, can develop wiring faults over time. Regular checks and maintenance are crucial, typically at intervals of around 15,000 to 30,000 km for oil service and brake systems.

Moreover, the cooling system deserves special attention, particularly around 150,000 km, when it’s advisable to inspect the water pump, thermostat, and radiator hoses. Ensuring these parts are replaced will help avoid overheating and engine failure. Don’t forget about regular brake service, too! Front and rear brake systems should be serviced every 15,000 km or as needed to ensure safety and reliability—check out our Brake Service options here.
