The Mercedes-Benz G-Class W465 is a part of the G-Class series of off-road vehicles, which are known for their ruggedness and durability. The W465 refers to the earlier generation of the G-Class, typically spanning from the 1980s to the early 2000s. Over time, the G-Class has been upgraded, but the W465 models were among the earliest to use advanced off-road technologies, including CV (constant velocity) joints.

CV Joints in the G-Class W465

CV joints are essential components in the drivetrain system of vehicles with all-wheel drive (AWD) or four-wheel drive (4WD). They enable the transfer of power to the wheels while allowing for movement in suspension systems, particularly when turning or going over uneven terrain. In the case of the G-Class W465, the CV joints are found in the axles of the vehicle, typically in the front axle (for vehicles with 4WD) and sometimes in the rear axle, depending on the specific drivetrain configuration.

Purpose of CV Joints:

• Power Transfer: They help deliver power from the engine to the wheels.
• Smooth Operation: They allow the wheels to turn while ensuring the drivetrain remains engaged even when the suspension is moving.
• Handling Rough Terrain: For an off-road vehicle like the G-Class, the CV joints are crucial for maintaining performance on uneven or rocky surfaces.

Common Types of CV Joints in the W465:

1. Outer CV Joints (Tripod or Rzeppa): These are often found near the wheels and allow for a greater range of motion during suspension travel.
2. Inner CV Joints (Fixed or Sliding): These connect to the transmission or transfer case and are generally fixed or sliding based on the drivetrain configuration.

Maintenance and Common Issues:

• Wear and Tear: Over time, CV joints can wear out due to constant movement, exposure to dirt, water, and other environmental factors, especially in off-road conditions.
• Grease Leaks: The protective boots around the CV joints can crack or tear, leading to grease leaks and exposure to contaminants.
• Noises: If a CV joint becomes damaged or the boot fails, it can result in clicking or popping noises when turning or accelerating.
• Replacement: Depending on the wear and tear, replacing CV joints can be necessary, and it's essential to use high-quality parts to maintain the vehicle's off-road capabilities.

Upgrading or Replacing CV Joints:

If you are experiencing issues with the CV joints in your G-Class W465, it is recommended to use OEM (original equipment manufacturer) or high-quality aftermarket parts to ensure durability. It's essential to inspect the CV joints periodically, especially if the vehicle is used in harsh off-road conditions.
