Land Rover Range Rover front differential failure causing excessive noise on Land Rover Range Rover

Some Land Rover Range Rover owners report experiencing excessive noise from the front differential, which may manifest as a drumming or whirring sound from the front foot-well area that can escalate to banging or whining noises, indicating potential issues with the PTU, front differential, or failing IRD nose bearing. Additionally, some owners notice a clunking noise when transitioning from power to overrun, which can be checked by driving in locked second gear at low speeds and listening for clunks that suggest play in the driveline. Furthermore, if unlocking the center differential produces a grinding noise from the front axle when engaging the clutch, it may signal failed splines between the gearbox and transfer box, often due to insufficient lubrication leading to wear and slippage. Recognizing these symptoms is crucial for timely intervention and maintaining safety on the road.
