Steering Knuckles
Ball joint catalog for the suspension system
In this section we offer a wide variety of ball joints specifically designed for the maintenance of the suspension system in heavy-duty and commercial vehicles. These components are essential for connecting the control arms to the steering knuckles, allowing the angular movement required for safe driving and absorbing road irregularities.
Our offer is aimed at workshop professionals and fleet managers looking for reliable replacement parts. Here you will find components compatible with various truck and bus brands, manufactured to withstand heavy loads and the intensive use typical of industrial transport.
How to identify the correct replacement
- Verify the original (OEM) reference of the part to be replaced.
- Confirm the mounting side (universal, right or left) and position (upper or lower).
- Check the exact dimensions of the taper and the thread pitch of the stud.
- Ensure compatibility with the vehicle’s model, year, and axle type.
- Review whether the part includes the necessary fastening accessories (nuts or cotter pins).
Frequently asked questions
What is the function of the suspension ball joint in a heavy-duty vehicle?
Its main function is to act as a pivot point between the suspension and the chassis, allowing the wheel to move vertically while maintaining steering capability. It is a crucial element for maintaining geometry, alignment, and vehicle stability under heavy workloads.
When should a suspension ball joint be replaced?
Immediate replacement is recommended when detecting steering play, dry metallic noises when driving over bumps, unusual vibrations in the steering wheel, or irregular and premature tire wear. Ignoring these symptoms may compromise vehicle safety.
Are ball joints universal for trucks and buses?
No, each manufacturer and vehicle model uses specific technical specifications in terms of size, mounting geometry, and material strength. It is essential to check the technical data sheet and cross-reference part numbers to ensure correct installation and avoid mechanical failures.
Is it necessary to align the vehicle after replacing ball joints?
Yes, it is highly recommended. Any intervention involving the removal of suspension or steering geometry components may alter the original settings. Performing an alignment afterward ensures optimal vehicle handling and maximizes tire lifespan.
