This range covers Kia, Mazda, Nissan and Volvo drivetrain parts, catalogued by OEM number and by position.
Most drivetrain complaints start at a joint. A CV joint whose boot has split loses its grease and takes in grit, and the first sign is usually a click on full lock rather than a vibration. A worn centre bearing or a failing universal joint shows up as a shudder under acceleration that fades when you lift off, which is the opposite of a wheel balance problem.
Check the boots for splits and grease loss at every service. Listen for clicking on turns, clunks when engaging drive, or a vibration that appears only under load. On a lift, feel for play in the joint and check the shaft for a wear groove where the seal has been running.
Each listing states the position (front or rear, left or right), the model years, engine and drivetrain and the OEM part number. All-wheel drive and two-wheel drive shafts are not interchangeable, and neither are left and right on most applications.
