Ersatzteile für Nutzfahrzeuge
ABS modulators control brake pressure to prevent wheel lock during braking. Learn how they work, which faults can produce ABS warnings and why a modulator fault should be distinguished from sensor, wiring and pneumatic problems.
Torque rods and bushings help control axle movement and maintain chassis geometry in commercial vehicles. Learn how wear develops, why correct dimensions matter and what to check when selecting replacement parts.
Trailer EBS coordinates electronic braking between tractor and trailer using standardized communication interfaces. Learn how the system works, which components are involved and why EBS faults require more than simple ECU replacement.
High-voltage battery packs in electric commercial vehicles combine cells, modules, thermal management and electronic control. Learn how these systems are structured and what workshops should consider when diagnosing battery faults.
Correct wheel fastening depends on more than applying a torque value. Learn how clamping force, thread condition, tightening procedure and damaged studs or nuts affect wheel security in commercial vehicles.
Slow air pressure build-up does not automatically mean that the compressor is defective. Learn how air leaks, the air dryer, pressure control and compressor performance can affect commercial vehicle pneumatic systems.
Shock absorbers control suspension movement and help keep commercial vehicle tires in stable contact with the road. Learn how damping works, which signs can indicate wear and why correct specification matters.
Height control valves regulate the ride height of air-suspended commercial vehicles. Learn how mechanical and electronic leveling systems work and what can cause uneven ride height or frequent air-system corrections.
Steering knuckles, wheel hubs and bearings work together at the commercial vehicle wheel end. Learn how the components differ, which symptoms indicate wear and why similar-looking hub and bearing assemblies are not always interchangeable.
Hydraulic and electrohydraulic steering systems provide steering assistance in different ways. Learn how both systems work, where their components differ and what workshops should consider when diagnosing steering problems.
