Framaxeln

Framaxeln, or the front axle, is the transverse component at the front of a motor vehicle that connects the front wheels to the chassis. It bears part of the vehicle’s weight, provides mounting points for the suspension, and serves as a mounting point for steering components. In many layouts the front axle also participates in the drivetrain, especially in front‑wheel‑drive vehicles where the axle or transaxle houses drive shafts.

There are two main configurations. A rigid (solid) front axle uses a single housing that spans both wheels and often includes a differential. An independent front suspension uses separate suspension arms and knuckles for each wheel, allowing independent vertical motion. In four‑wheel‑drive or all‑wheel‑drive vehicles the front axle may include a differential and be part of a system that transfer power to the front wheels.

The front axle plays a central role in steering and handling. It is connected to the steering system through components such as tie rods and steering knuckles, so turning the steering wheel causes the wheels to pivot around the axle. The suspension attaches the axle to the vehicle frame and defines ride quality and geometry, including camber, toe, and caster, which influence tire wear and handling characteristics.

Maintenance focuses on wear and seals. Common issues include worn ball joints or bushings, worn tie-rod ends, CV joints in front‑wheel‑drive layouts, wheel bearings, and axle or differential seals. Proper alignment is important for steering feel and tire longevity.
