Information - Wishbone

Wishbone is necessary to provide the movement of the wheel centre in a plane. This part is perpendicular to the longitudinal axis and is located along the longitudinal axis. It is also worth noting that none of the vehicle suspension is complete without this component. As for the most common for today McPherson suspension, wishbone suspension in this form is attached through the silent-blocks to the cross bar. It is connected to the wheel knuckle through a ball joint. The body of the car in such a structure serves as the upper arm, as it is attached to the damper strut. This design is ideal for very small and small class, but not suitable for other car classes.

Suspension on double wishbones with two elements that have a swing mount bearing on the frame, crossbar or body. This design provides connection of the outer ends by the use of ball joints with a steering knuckle or stub axle. Therefore, the bigger distance between the wishbones is the less force that acts in levers and bearings is. Thus, the parts are less subject to the force and hence the kinematics of the suspension is more precisely.

Multi-link suspension is used in front and rear suspensions. For optimal kinematics of the wheels, as well as for better stability and handling, there are used four or five levers. Two levers are needed to hold the wheel. Others provide necessary kinematics. In this case, it is not required to combine shock absorber and spring into the strut. It is also necessary to speak about all-wheel drive passenger cars, in which multi-link independent suspension is mainly used.

If you need to replace the wishbone, it is reasonable to do this in a car workshop. Still, it is much better to order the part you need in our online store. For instance, shock absorber, ignition coil or flange. Ordering online you will significantly save your time and money.

What is necessary to know about suspension arm replacement: lifetime limits, common defects and their signs, tips and recommendations

Operational lifetime of the suspension arms is 60,000 – 80,000 kilometers of car mileage. It greatly depends on road surface condition, where the car is used, and driving style. Apart from wear-out, defect of the front or rear suspension arms may be caused by various mechanical damages (cracks, breaks) and deformation.

Defect signs of the parts are screeching and knocking during driving on a rough road. When cornering, cracking and clicking may be heard from the suspension side. Moreover, signs of arms failure are: worsening of road-holding ability during straightforward movement. Defects of the arms (trailing arms or wishbones) may be indicated by uneven wear of tyres treads and significant free play of the steering wheel.

It is recommended to inspect the components at a service station. A lifting platform or a servicing pit are necessary for it. The parts are thoroughly inspected for presence of cracks or deformation and replaced if needed. It is better to entrust this procedure to specialists, as demounting of some other parts impeding access to the unit may be required.

Algorithm for replacement of the front and rear upper arms slightly differs from procedure of demounting and installation of the lower suspension arms. In any case, demounting of the wheels (front or rear) will be required, as well as cleaning of the suspension from dirt. Then, a specialist unscrews fasteners of the stabilizer link and demounts the ball joints. During removal of the rear lower arm, fasteners of the part to the stub axle and fastener of the part to the axle beam are unscrewed. Demounting the front lower arm (as well as the rear one), a specialist will disconnect the ABS sensor if necessary.

After this, a defective component may be dismounted. A new arm is installed in the order, reverse to the removal process. Having the part installed, a specialist will check wheels alignment and adjust if necessary.

During replacement of suspension arms, it is recommended to pay attention to condition of the ball joints, bushes, shock absorbers and stabilizers. By necessity, these parts should be replaced together with the arms.

Important advices for our customers

How to remove the suspension arm?

In order to remove the suspension arm, you will need a jack, mounts, a set of wrenches and screwdrivers and special equipment for arm bushes pressing out in case if bushes are to be replaced. Replacement procedure is quite difficult. For example, during installation of lower or upper wishbones and trailing arms or suspension demounting of wheels will be required together with their following alignment adjustment. Sometimes it is impossible to unscrew a rusted bolt without special oiling agents. Sequence of works during replacement of front and rear suspension arms may differ. For actions algorithm clarification during self-maintained repair, use instructions given in vehicle technical documentation.

How to check operability of front suspension arms?

To check operability of front suspension arms, firstly, inspect them visually: deformation, cracks, rubber delamination of bushes or dust caps indicate the necessity of worn elements replacement or components assemblies. Then you need to make sure that ball joints have no backlash. To do this you need to place the car onto inspection pit or a car ramp, suspend the front wheels off the ground and try to shake a proper arm using a tire iron. Apart of visual inspection condition of ball joints is checked with the help of a slide-gauge. To define the amount of axial displacement, you need to measure the distance between supporting washer and bush: if a joint is intact, it should be 1.5-5.0mm for upper and 3.0-7.5mm for lower arms.

An arm of which brand will be best to install?

It is better to install arms of well-known brands in your car. According to their prices, components may be divided into three categories:

  1. Premium segment. It is presented by production of such manufacturers as: Lemförder, Monroe, Stark Professional Line, TRW, Qsten. Arms of these companies are expensive, but their high price is compensated by continuous lifetime, which usually exceeds 120 000 operational kilometers.
  2. Mid-segment. Spare parts of this category are excellent alternative for high priced components. They are notable for high quality. They are designed for a mileage about 75 000 km. They are presented in the assortment of such companies as Moog, Ruville, Meyle, Diederichs, Febi Bilstein, Metzger, SWAG.
  3. Low-end segment. Components of such companies as Optimal, NK, JP Group, RIDEX, MAPCO, Quinton Hazell and VAICO are presented in it. Front suspension arms of this category help to save on a purchase, but also break down earlier than others: their approximate operational lifetime is about 40 000 km of mileage.
