On the 2000-2018 Mercedes-Benz G-Class, the front differential axle seals on the W463 G-Class are prone to leaking gear oil, particularly on higher-mileage vehicles. Oil seeps past the worn seals onto the brake components, potentially contaminating brake pads and reducing braking effectiveness. The solid axle design makes seal replacement more involved than on IFS vehicles.

This issue also affects: Land Rover Discovery, Mercedes-Benz SL-Class, Chevrolet C/K 1500

Common Symptoms

Oil residue on inner front wheels
Gear oil smell from front axle area
Brake pulling to one side
Visible oil on brake caliper or rotor

How to Fix

Replace both front axle seals and inspect the axle shafts for scoring. If brake pads are contaminated with oil, replace pads and resurface or replace rotors. Use genuine Mercedes seals for proper fitment on the solid axle housing.

NoteDo not ignore front axle seal leaks — oil contamination of brake pads is a serious safety issue. Replace both sides even if only one is leaking, as the other will follow soon.

On the 2000-2018 Mercedes-Benz G-Class, the recirculating ball steering system on W463 G-Class models relies on a steering damper that wears out over time, causing excessive highway wander, steering wheel vibration at speed, and a vague on-center feel. The solid front axle design amplifies these symptoms compared to independent suspension vehicles.

This issue also affects: Land Rover Discovery, Mercedes-Benz SL-Class, Chevrolet C/K 1500

Common Symptoms

Highway steering wander
Steering wheel vibration at 55-70 mph
Vague on-center steering feel
Clunking over bumps from front end

How to Fix

Replace the steering damper with an OEM or upgraded aftermarket unit such as Bilstein B6. Inspect the drag link and tie rod ends for play simultaneously. Perform a front-end alignment after replacement.
