Ready to ShipMany power steering racks for w210 models are available, each with unique features that enhance vehicle maneuverability and control. Here are some common types:
Standard Power Steering Rack
This is the most common type of steering rack found in the W210. It combines hydraulic power steering with a rack and pinion layout. The hydraulic system uses the driver's effort to steer the vehicle. The standard power steering rack provides a good balance between steering control and vehicle maneuverability.
Variable Ratio Steering Rack
Some W210 models are equipped with variable ratio steering racks. The steering rack varies the gear ratio depending on the steering angle. This results in precise control of the vehicle at high speeds and quick response when turning the steering wheel at low speeds.
Speed Sensitive Power Steering Rack
The W210's speed-sensitive power steering racks automatically adjust the steering effort required based on the vehicle's speed. As the vehicle gains speed, the steering becomes heavier, preventing drivers from oversteering. Conversely, the steering wheel becomes lighter when the vehicle moves at low speed. This feature improves vehicle stability at high speeds and increases maneuverability at low speeds.
Cross-Linked Power Steering Rack
Some W210 power steering racks are cross-linked. The steering racks of the left and right wheels are interconnected. This design ensures that both wheels receive equal steering effort and improve vehicle stability, especially when cornering. The cross-linked power steering rack is suitable for high-performance and luxury vehicles.
Electro-Hydraulic Power Steering Rack
Some modern vehicles use electro-hydraulic power steering racks. These racks combine the traditional hydraulic system with an electric motor. The electric motor controls the hydraulic assist based on the driver's input. This results in a more precise and responsive steering system. The electro-hydraulic power steering rack also improves fuel efficiency by reducing parasitic losses associated with the hydraulic system.
Specifications for the power steering rack vary depending on the model number, but here are some general specifications to expect from a power steering rack.
Steering Ratio
The steering ratio describes the number of degrees the steering wheel must turn to move the wheels one degree. In simpler terms, it is the ratio of the angle of the steering wheel to the angle of the wheels. This ratio affects how drivers control their vehicles. A low ratio means more wheel turns to increase the angle of the wheels. It allows for precise control, making it ideal for racing. A high ratio offers quick responses, making it suitable for off-road driving.
Power Assistance
Power assistance refers to the amount of energy applied to the steering wheel by the steering system. The power assistance feature eases the steering wheel's effort during vehicle movement. Power assistance also varies depending on the vehicle's speed. For instance, the steering wheel may require more effort at high speeds compared to low speeds.
Turn Angle
The turn angle is the maximum angle the steering wheel can turn. This feature determines how much the driver can turn the vehicle's direction. A large turning angle gives the driver more control. It allows for tighter turns. A smaller angle, on the other hand, allows the driver to turn the vehicle's direction quickly.
Pinion Diameter
The power steering rack pinion diameter is the smallest circular gear in the steering system. It interacts with the steering gear to convert the steering wheel's rotational movement into linear movement. The pinion gear teeth engage with the rack's teeth to enable the vehicle's side-to-side movement. A larger pinion diameter increases the force applied to the steering wheel, making it tight. On the other hand, a smaller diameter results in a loose steering wheel.
Steering Effort
Steering effort refers to the amount of force the driver applies to the steering wheel while driving. This feature is affected by the steering ratio, power assistance, and friction in the steering system. A high steering effort makes it difficult to control the vehicle. On the other hand, a low steering effort means the driver can easily control the vehicle's direction.
Here are some maintenance tips for the power steering rack maintenance business.
Check the power steering fluid
Power steering fluid is the lifeblood of the system and requires regular maintenance. The fluid level should be at the recommended level, while the condition should be free from contaminants. Fluid leaks should also be checked, as they can damage the entire system. Furthermore, the fluid should be changed at the manufacturer's recommended intervals to maintain the system's performance.
Inspect the hoses and belts
The power steering system relies on high-pressure hoses to transport fluid and belts to drive the pump. Regular inspection of these components is crucial in power steering maintenance. Look out for signs of wear, damage, or leaks, as these can affect the system's efficiency. Worn-out belts can also slip or break, leading to pump failure.
Check the steering rack
The steering rack is the heart of the power steering system. It requires regular inspection to check for signs of wear, damage, or leaks. The condition of the steering rack directly affects the vehicle's steering performance. Also, the steering rack should be checked for play or binding, as these can affect the steering precision and control.
Inspect the power steering pump
The power steering pump requires regular inspection to check for signs of wear or damage. It also requires checking for fluid leaks and unusual noises, such as grinding or whining. The power steering pump should be removed and inspected if there are signs of a steering problem.
Lubricate the steering components
The steering components need regular lubrication to enhance their performance and increase their lifespan. Use the recommended lubricant to lubricate the steering shaft, joints, and other moving parts. Avoid over-lubrication, as this can attract dirt and lead to component wear.
Choosing a power steering rack for Mercedes 210 can be a difficult task for retailers. There are lots of factors to consider, and the most important is knowing what the customers want. Here are a few tips to help source the right power steering racks for the business.

It's not easy to work on a steering rack, and it isn't a good idea to attempt to bleed a hydraulic power steering system without the right tools. However, changing the power steering fluid is a relatively easy DIY project. Relying on the owner's manual is essential to locate the proper reservoir and hose routing and get the correct fluid for the vehicle. Here are some steps to follow when DIY;
Locate the power steering fluid reservoir in the W210. It is usually situated near the engine's front, close to the steering rack. Clean the reservoir's exterior to prevent contaminants from entering the system. Remove the reservoir cap and use a turkey baster or siphon pump to remove as much old power steering fluid as possible. Dispose of the old fluid properly.
Attach a siphon pump or a flexible hose to the reservoir's outlet port. Prepare a drain pan and use the siphon pump or hose to drain the fluid from the system. The fluid will flow out of the outlet port into the drain pan. This step may require a helper to turn the steering wheel while the fluid is being drained.
With the fluid drained, disconnect the power steering hoses from the steering rack. W210 users can consult the service manual for specific instructions. Be prepared for some residual fluid to leak out. Quickly reattach the hoses to avoid contamination and leakage.
Now, it's time to refill the system. Locate the power steering fluid reservoir and fill it with new fluid. Turn the steering wheel from lock to lock several times to bleed air from the system. This helps to circulate the new fluid and remove any trapped air. Keep an eye on the fluid level in the reservoir and add more if necessary to maintain optimal levels.
After the process is done, W210 users should start the engine and turn the steering wheel to ensure the power steering system functions correctly. Check for any leaks around the hoses and the steering rack.
