Suspension joints by LEMFÖRDER ensure greater agility, enhanced stability and more strength, making the car safer and more durable through optimal elasticity and lower friction torques. They are integrated into the control arms, pressed-in or flange-mounted. Alternatively, they can be pressed or screwed into the wheel carrier.

With our unique ball joint tempering process, service life is greatly extended, ensuring greater agility, enhanced stability and more strength, making the car safer and more durable through optimal elasticity and lower friction torques.
High grade material ball pin – with tensile strength of up to 1100N/mm2 following ISO standards of 6892-1.
Lightweight and corrosion and chemical resistant – the polymer bearings offer a much smoother steering returnability.
Heat treated forged housing – with hardness of up to HV 380 to provide better durability and promote safety.
Precise application of special greasing – applied evenly to the whole ball for longer life and better steering.
There’s a reason that every third ball joint produced worldwide is made by LEMFÖRDER.

The (wheel) suspension ball joint establishes the connection and, consequently, the support between the front axle control arms and the axle body/carrier (steering knuckle). Its task is to guide the wheel carrier and wheel, to enable the spring deflection of the wheel and to permit the steering movement on the front axle. It is always installed at the triangle apex of the control arm. The height fixation is performed via the ball stud. The ball joint should be easy to move, low in flexibility, maintenance-free and noise-insulating. These four, partly contradicting, requirements are met at LEMFÖRDER, for instance thanks to premium plastic shells in the joint.

In terms of design, the suspension ball joints and the supporting joints are only marginally different from one another. The supporting joint is located on the opposite side of the suspension ball joint, assembled in the steering knuckle. It absorbs forces in all directions and can be installed in a suspended or vertical manner. The ball joint housing is usually attached in the control arm and the ball stud is usually attached on the inside of the steering knuckle via its conical taper or a cylindrical dog point. Advantage: This mounting is maintenance-free.

Cross-axis joints are primarily installed on the rear axle. They consist of a ball with cylindrical taper on both sides and a continuous bore in the middle. Although they are similar to the ball joint in terms of function and structure, their anchorage corresponds to that of rubber bearings. In contrast to rubber bearings, cross-axis joints are able to transfer extremely high dynamic forces and have no aligning torque. Cross-axis joints are preferably used if a stiff control arm connection is desired – in sports cars or light commercial vehicles for instance.

Quality for the workshop
A vehicle fitted with LEMFÖRDER parts throughout will respond with smoother steering and more dynamically than it would if it was fitted with replica parts. In the event of repair this should be considered.
Precision-engineered, hardened studs with rolled threads don’t just meet OEM design standards, they exceed them.
For an optimized product performance the radial and axial spring travel is measured to ensure the precise product dimension.
LEMFÖRDER consistently achieves significantly lower breakaway torque values – the force required to move the ball-pin when the steering wheel turns for the first time – than its competitors.
