When operating a vehicle or during a conversation in a service center, drivers often face the need to accurately determine the location of the nodes. The question of where is right-handerIt may seem elementary, but in real practice there is confusion, especially when it comes to the side of the car regarding the direction of movement or the position of the person standing outside. Identification errors lead to the order of incorrect spare parts or incorrect diagnosis when inspecting the chassis and body.
In the automotive industry, there is a clear rule: all sides are determined by the driver sitting in the chair and looking forward as the movement progresses. Consequently, right-hander This is the part located on the right side of the driver. However, it is important to distinguish which rack is in question: the rack. shock absorber pendant body-stack (A, B, C) because their functions and methods of verification are radically different.
Improper identification of the side can cost you time and money, especially when ordering parts through online stores, where refunds are often at the buyer’s expense. In this article, we will discuss in detail the geometry of the car, methods of visual and tactile diagnostics, as well as touch on the nuances associated with specific brands of cars. Understanding these differences is necessary for every owner who wants to competently service their transport.
Principles of orientation: how to determine the right side
The fundamental principle in the automotive industry is the binding of coordinates to centreline cars. Imagine you are driving and looking at the road. Everything on the right hand of your car is on the right side of the car. This rule is universal and applies regardless of whether left-hand or right-hand traffic is accepted in the country of operation. Even if the steering wheel is on the right (as in Japan or the UK), right-hand It is left to the right with respect to the longitudinal axis of the body.
Many beginners make the mistake of approaching the car from the front and trying to identify the sides "from themselves." In this case, their left hand will point to the right side of the car, causing confusion when ordering parts. To avoid this, always mentally drive. If you are outside, bypass the car counterclockwise: first there will be a starboard, then a rear, a left side and a hood. Right pillar in this context, will be on board, where right-hand drive cars have a steering wheel, and left-handed cars have a passenger seat.
⚠️ Warning: Never rely on mirror imagery in store windows or catalog photos without marking "back view." An error in the definition of the side leads to the purchase of a shock absorber with the wrong location of fasteners or ABS sensors.
For the precise definition of the sides can also be used VIN code And spare parts catalog diagrams. In electronic catalogs, parts are often marked with the letters R (Right) and L (Left). The part marked R is designed to be installed on the right side, that is, where it is located. right-hander. This is especially true for asymmetric suspension parts where the mountings may differ.
Right pillar of shock absorber: location and signs of malfunction
When it comes to the undercarriage, right-handed Most often mean a shock absorber or a McPherson rack, located in the right front or rear corner of the car. This unit experiences enormous loads, extinguishing the fluctuations of the body when moving on irregularities. It is located directly above the right front wheel (if we are talking about the front axle) and is attached to the rotary fist from below and to the body or spanger from above through the supporting bearing.
Diagnosis of the right rack requires careful examination. Often drivers notice problems only when there is a knock or the car begins to “scour” along the road. However, there are hidden signs indicating wear and tear. right-hand shock absorber. For example, with a sharp braking, the car can lead to the right if the right pillar has lost elasticity and does not hold the load as well as the left one.
Visual inspection of the right front pillar is better carried out on the lift or observation pit. Pay attention to the condition of the anther and the breaker. If the rubber anther is torn, dirt gets inside, which destroys the rod and the osteoils. It is also critically important to check the presence of oil stains on the shock absorber body. Even a slight fogging may indicate a violation of the tightness of the valves.
When replacing the racks, change them in pairs on one axis. Installation of a new right rack to the worn left will lead to uneven roll of the body and rapid failure of the new part.
There are several key symptoms that require immediate intervention:
- 🔊 The appearance of a deaf knock or creak in the right front part when passing irregularities.
- 📉 A noticeable roll of the body to the right with static parking on a flat surface.
- 💧 The presence of oily traces on the shock absorber rod or the rack body.
- 🚗 Take the car away when driving on a straight track.
Body pillars: Scheme A, B, C and their role in safety
In the context of body repair and safety, the term “pillar” refers to the vertical supports of the roof of a car. Right front pillar In the automotive nomenclature is called the "A" stand. It is located on either side of the windshield. It is the right-hand stand "A" often interferes with the view when leaving the intersection from a secondary road, creating the so-called "dead zone". The design of this rack is enhanced by internal metal profiles to protect passengers in frontal impact.
Behind the front counter follows right middle pillar (pillar "B"). It is located between the front and rear doors in five-door bodies or between the door and the rear wheel arch in three-door hatchbacks. This is the most loaded element of the frame, providing the rigidity of the body to twist and protect during lateral impact. In some models, for example, in Mazda or BMWThe mid-stacks can be shifted back to improve aerodynamics or design.
The back of the roof is based on posterior (The "C" or "D" stand in station wagons). In sedans, it connects the roof to the rear shelf, and in hatchbacks smoothly goes into the arch. Damage to these elements in an accident requires complex body repair, as they are part of the power frame. Restoring the geometry of the racks is critical for the proper opening of doors and the operation of security locks.
Why are the racks painted black?
The black color of the racks (especially the middle and rear) is used for the visual effect of the “floating roof”. This makes the glazing more solid and hides the massive power elements, making the car more elegant.
The table below shows the differences in the purpose of body racks:
| Designation | Location. | Substantive function | Risks of damage |
|---|---|---|---|
| Stand A (Right) | At the right edge of the windshield | Glass fixing, frontal impact protection | Breaching, risk of head injury |
| Stand B (Right) | Between the right front and back door | Body rigidity, seat belt anchorage | Deformation of door opening, failure of belts |
| Stand C (Right) | Back corner of the roof on the right | Roof support, formation of luggage opening | Difficulty opening the trunk, corrosion |
Diagnostic methods: how to check the condition of the right rack
Technical serviceability check right-hand-holder It starts with a simple test of scaling. Approach the right front corner of the car and press the wing with both hands, then let go abruptly. The body must swing up, come back down and finally stop. If the oscillations continue for more than one or two cycles, then the valve mechanism of the shock absorber is worn out and does not extinguish the inertia.
More accurate diagnosis can be carried out only after the wheel is removed. In this case, access to the Silent blocks of levers, ball supports and the rod itself is opened. Swing the wheel with your hands in vertical and horizontal planes. Luft in the vertical plane often indicates wear itself shock-stack Or her bearing. Horizontal backlash is more likely to indicate problems with the steering tip or ball support, but can sometimes be caused by the destruction of the bottom of the rack.
⚠️ Warning: When checking the racks on the lift, never leave the suspension hanging unloaded if you plan to unscrew the nut of the shock absorber rod. The spring is under enormous pressure and can fire, causing severe injuries.
It is also worth paying attention to the nature of the noise. Deaf knocking when passing "lying policemen" often indicates broken bushings of the stabilizer or wear of the support of the rack. A bellowing metal clang may signal that the shock absorber rod is dangling in the body due to the development of a guide sleeve. For modern cars with adaptive suspension, it is important to check the electrical connectors suitable for the right-hander. Oxidation of contacts can lead to an error in the comfort system.

Replacement and maintenance: technical nuances
Replacement right-hander requires a specialized tool, in particular, screeds for springs. Without them, dismantling the McPherson knot is impossible and deadly. First, you need to dismantle the wheel, disconnect the brake hose (if it is fixed on the rack) and the wire of the ABS sensor. Then the bolts of the mounting of the rack to the rotary fist and the nut of the upper mounting in the engine compartment are unscrewed.
When installing a new part, it is necessary to observe the tightening moment of the threaded connections specified in the manufacturer's manual. An insufficient puff will lead to knocks, and a tightening can damage rubber metal hinges. Pay special attention to the installation of the bearing: it must be guided strictly by the marks, otherwise, when turning the steering wheel, a crunch will occur. The right rack often has asymmetrical mounts, so it is quite difficult to confuse the top and bottom during installation, but it is possible when using non-original analogues.
After replacing any front suspension rack, adjustment of the wheel installation angles (fall-down) is required. Ignoring this stage will lead to rapid and uneven wear of the tires, as well as deterioration of the course stability of the car. Even if the wheels are visually flat, microscopic changes in the geometry of the suspension after the parts are replaced are essential for dynamics.
There is a common misconception that you need to change only the rack that knocks. The left and right side are about the same. If she's incapacitated right-handerThe left, most likely, has exhausted its resource by 80-90%. Installing a new part in a pair with the old will lead to an imbalance of stiffness, which is dangerous at high speeds and in cornering.
Replacement of shock absorber racks is a procedure that requires subsequent mandatory adjustment of the collapse-convergence to preserve the manageability and resource of the tires.
Impact of road quality and climate on the resource of racks
Resource right-hander It depends on the operating conditions. In regions with cold climates and the use of reagents on the roads, the corrosion resistance of suspension elements is reduced. Salt, falling under the anther, turns into an abrasive porridge, which quickly wears out the rod and oils. The right side often suffers more, as on one-way roads or narrow streets, it is the right wheels that are more likely to come into contact with the roadside, where dirt and chemistry accumulate.
The quality of the road surface also plays a critical role. Frequent impacts on deep pits at high speed lead to deformation of the rod or the destruction of the piston inside the shock absorber. Even a single strong blow can disrupt the work of the valve group, which will lead to a loss of efficiency of quenching the oscillations. Drivers who often drive on bad roads are advised to diagnose the suspension every 15-20 thousand kilometers.
Temperature differences affect the elasticity of rubber elements: Silentblocks, bushings and anthers. In the cold, rubber bluffs and cracks, opening the way to water and dirt to rubbing metal parts. Right pillarLike the left, it requires the use of frost-resistant lubricants during maintenance. Ignoring seasonal maintenance can cut the life of a node by half.
How to prolong the life of shock absorber racks?
For maximum resource, avoid sharp braking in front of the pits (so the load on the suspension is less), do not accelerate sharply to the "lying policemen" and wash the wheel arches in the winter from reagents. It is also useful to lubricate the shock absorbers with silicone lubricant with each tire replacement.
Can I drive with a faulty right-hand desk?
You can drive, but it's very dangerous. A faulty rack increases the braking distance, can lead to aquaplaning on a wet road and loss of control of the car in an emergency. In addition, the collapsing shock absorber can damage other suspension elements.
Which is better, gas or oil?
Gas-filled racks are stiffer and better hold the road at high speeds, but transmit more vibrations to the body. Oil shock absorbers are softer and more comfortable in the city, but are prone to suffocation and overheating when driving actively. The choice depends on the driving style and the quality of the roads.
Why is the new counter knocking?
The knock of the new rack can be caused by an incorrect tightening of the fasteners, the defect of the part itself, the absence of lubrication in the bearing support or the fact that the accompanying elements (supports, bushings) that have already been worn have not been replaced during the replacement.
