Tie Rod

Safely on Track

The ideal connection between steering system and steering knuckle

Tie rod in the car

Optimum straight-line running of a car ensures driving comfort, controllability and reduced tire wear. To ensure that passenger cars, vans and light commercial vehicles always stay on the ideal track, high-quality POLADIUM tie rods should always be used for repairs. They perfectly transfer the steering movements of the driver to the front wheels of the vehicle and enable the workshop to adjust the toe-in precisely and sensitively.

POLADIUM tie rods for passenger cars, vans and light commercial vehicles ensure precise steering and safe handling. The forces introduced into the steering gear are transmitted via the inner axial joint through the tie rod to the outer ball joint, the tie rod end piece. A thread in the middle of the wheel allows for sensitive adjustment of both wheels.

The connections and joints of the tie rod in particular place high demands on the design. POLADIUM offers a wide range of high-quality solutions, optimized for installation spaces and the materials. Know-how acquired over decades in research and development pays off, especially with POLADIUM products for the aftermarket.

The axial joint

The steering gear-side tie rod joint is referred to as axial joint. It can transmit axial forces of up to 25 kN. The axial joint is mainly used on rack-and-pinion steering systems.Angles of up to 60° are possible here. POLADIUM produces various designs of a high quality:

Housing with threaded pin.

Housing with internal thread.

Housing with tapped hole with vibration-damping rubber element.

The tie rod end

The tie rod is a part of the steering mechanism in a vehicle. The tie rod transmits force from the steering center link or rack gear to the steering knuckle. This will cause the wheel to turn. The outer tie rod end connects with an adjusting sleeve, which allows the length of the tie rod to be adjustable. This adjustment is used to set a vehicle’s alignment angle.

Tie rod ends should be regularly inspected with each oil change service, by a qualified technician. They are a wearing part of the steering and suspension system of your vehicle. As tie rod ends wear, they can become loose and can develop excessive slack, or play, which can be felt in the steering and handling of the vehicle. Bad tie rod ends can negatively impact a vehicle’s front end alignment and lead to excessive tire wear and front suspension problems. Tie rod ends are critical to maintaining proper vehicle front suspension alignment.

The most common signs of bad tie rod ends are: vehicle pulling to one side during operation, uneven tire wear, shaking, vibration, looseness, or a wandering or erratic feel to the steering of the vehicle, and squeaking noises coming from the front end of the vehicle.

If a tie rod end fails completely a driver will loose the ability to steer and control the vehicle. Regular inspections of the tie rod ends and replacing them when it is either advised or as symptoms start to occur is recommended. It is also recommended to have an alignment performed or at least checked once these parts are replaced.
