The systems have evolved over the years, but the goal has remained the same: maximizing traction by sending power to all four wheels.
CV Axle Installation Tips
CV joint shafts are typically being replaced at anywhere from 70,000 to 130,000 miles.
Subaru Drivetrain Noise Diagnostics
To reduce noise, some Subaru driveshafts use a special constant velocity joint to connect the two pieces of the driveshaft.
Driveshafts: Can 10,000 Applications Really Be Covered By Two Parts?
Shops and part suppliers are always looking for ways to make technicians’ lives a little easier. In recent years, many parts like CV axles, strut/spring assemblies and suspension control arms have been introduced to allow technicians to simply install a complete component instead of repairing parts of the existing assembly. But this parts philosophy does
Driveshaft Universal Joint Tips And Techniques
Many vehicles use a “staked” universal joint, which means it is welded or locked in place.
Drivetrain: Diagnostic Test Drive
Once the vehicle is moving, you might hear a whine coming from the center of the vehicle. The noise will change as speed increases and might change as power is applied.
CV Axle Diagnostic And Service Tips
For inner plunge joints, the axle could bottom out. If the replacement axle is close, but not exactly made to the correct specifications, the misalignment of the axles can be even more compounded.
Nissan Titan Rear Axle Service
The 2004-2015 Titan was Nissan’s first attempt at a full-sized truck for the North American market. It could be ordered as a fleet truck or as a fully optioned 4×4.
Steering It Straight In 4-Wheel Drive Vehicles
AWD vs. 4WD: In contrast to an all-wheel drive (AWD) vehicle, a four-wheel drive vehicle is typically equipped with a two-speed transfer case capable of driving in two or four-wheel drive and a Hotchkiss or “solid” rear drive axle for main propulsion. A four-wheel drive might incorporate either a solid front axle as with older Toyotas and Nissans or an independent front suspension as found in more modern configurations.

Mercedes-Benz Tech Tip: Howling Noise From Rear At 50-70 MPH
Vehicle owners may complain of a howling noise in the drivetrain in the area of the rear axle between 80 km/h and 110 km/h (50 mph to 70 mph). The cause could be resonance in the drivetrain stimulated by the meshing of the gear set in the rear axle differential (drive pinion/ring gear).
