Product Description
This air shock absorber core (strut) is designed for the front air suspension system of the Mercedes-Benz 213 chassis, specifically for the 2WD front right (passenger side) position. This product is a strut-only component and does not include an air spring. It is suitable for repair scenarios where the original front air spring is still fully functional but the strut damping has degraded or failed.
Unlike the 4WD version, the 2WD front axle on the 213 chassis has no drive half-shafts or front differential, making the front axle weight lighter. Therefore, the damping of the 2WD front strut is tuned more toward comfort to match the positioning of the E-Class executive sedan. Through an internal hydraulic valve system, this strut precisely regulates compression and rebound rates, providing sufficient support to suppress body pitch while maintaining soft vibration filtering.
The front right strut is located on the passenger side, forming a symmetrical damping match with the left side strut. This product features damping optimization specifically matched to the load characteristics of the 2WD front right axle. It is manufactured to original equipment structural dimensions, with the lower fork mounting bracket, top fixing threads, and bump stop limit positions all consistent with original factory specifications, allowing direct replacement of the old strut without any modifications.
Important Note
⚠️ This product is suitable for Mercedes-Benz 213 chassis E-Class 2WD (rear-wheel drive) versions (e.g., E200, E260, E300 2WD, etc.), model years 2016-2023. The front axle structure of the W213 (sedan) and S213 (wagon) is identical, and the strut is compatible with both. For 4WD (4MATIC) versions, the front axle has additional drive half-shafts and different weight characteristics, resulting in different damping calibration. Please confirm your vehicle's drive type before purchasing. Vehicles without a "4MATIC" badge on the rear are 2WD versions. Differences may exist between different model years and configurations. Please verify the original OE part number or VIN code before purchasing.
Frequently Asked Questions
Q1: How can I tell whether the Mercedes-Benz 213 2WD front right strut is already damaged?
Common signs of damage include: a hollow, loose "thumping" noise when the right front wheel goes over speed bumps, increased front-end dive to the lower right side during braking, noticeably stronger front-end lift on the right side than the left during acceleration, and faster wear on the inner side of the right front tire compared to the left. A simple self-check method: after stopping the vehicle, press down firmly on the right front fender and release quickly. If the body bounces up and down more than twice before stopping, the damping on the right side has significantly degraded.
Q2: Are the 213 front right and front left struts interchangeable?
No, they are not interchangeable. Although similar in appearance, the left and right front struts on the 213 differ in internal damping valve calibration to accommodate the E-Class's left-right load distribution. Forcibly swapping them will result in asymmetric support on both sides of the front axle during cornering, affecting the E-Class's expected ride stability.
Q3: After replacing the front right strut alone, is it necessary to also replace the left side?
Replacing in pairs is not mandatory; the right side can be replaced alone. However, if the left side strut has been in service for a long time (over 70,000 km or 5+ years), its damping force will differ from the new strut, which may cause the vehicle to lean slightly to one side during cornering or unstable front-end behavior during braking. It is recommended to decide whether to replace both sides based on the actual condition of the left side strut.
Q4: After replacing the strut, the instrument panel shows an "AIRMATIC Malfunction" warning, but the vehicle drives normally. What is the cause?
This situation is usually not a problem with the strut itself, but rather the air suspension system has not been reset after installation. After replacing front suspension components, a diagnostic tool is required to perform "level calibration" and "component learning" on the AIRMATIC system. It is recommended to connect a diagnostic tool after installation, clear the fault codes, and perform front axle height initialization.
Q5: Is the 213 2WD front right strut suitable for the 4WD E-Class?
No, it is not interchangeable. The 4WD (4MATIC) front axle has added drive half-shafts and a front differential, making the front axle weight significantly higher than the 2WD version. The 2WD strut has softer damping; installing it on a 4WD vehicle will result in insufficient support, severe brake dive, and increased body roll during cornering.
Q6: Are the W213 and S213 front right struts interchangeable?
Yes, they are interchangeable. The front axle suspension structure of the W213 (sedan) and S213 (wagon) is completely identical. The strut mounting dimensions, piston rod diameter, and damping characteristics are all the same, making them interchangeable.
Q7: What accessories are recommended to replace at the same time as the front right strut?
It is recommended to replace the following accessories simultaneously: the front strut dust boot, the upper bump stop, and the top nut securing the piston rod. In addition, check the right front stabilizer bar link ball joint for looseness and the right front lower control arm bushing for aging or cracking.
Q8: After replacing the strut, the right front suspension feels bumpier than before. Is this normal?
Yes, this is normal. Over long-term use, the damping oil inside the old strut gradually degrades and damping force decreases. After the new strut restores the original factory damping level, the road feel becomes more noticeable. Typically, after driving 300-500 km, the strut will gradually break in to a stable condition.
Q9: There is a "squeaking" or "creaking" noise from the right front wheel area while driving after strut replacement. What is the cause?
Common causes include: 1) The top nut of the strut is not tightened to the specified torque; 2) The dust boot is not installed properly and is rubbing against the strut body; 3) The right front stabilizer bar link ball joint is aged; 4) The right front lower control arm bushing is aged. It is recommended to first check the stabilizer link and control arm bushings.
Q10: Is a wheel alignment (chassis angle calibration) necessary after replacing the 213 2WD front right strut?
It is strongly recommended. The 213 chassis E-Class front suspension is a double-wishbone design. Removing the strut involves disconnecting the upper and lower control arms from the steering knuckle, which will affect front wheel alignment parameters. Common consequences of skipping wheel alignment include: unstable steering wheel at high speeds, uneven tire wear, and pulling to one side when driving straight.
Q11: Are the 213 front strut and rear strut interchangeable?
Absolutely not. The front and rear struts have fundamental differences in body length, piston rod diameter, mounting method, and damping valve tuning. Forcing interchangeability will result in chassis dynamic imbalance and seriously affect the E-Class's expected driving stability and comfort.
Q12: Is the 213 2WD front right strut suitable for the later generation W214 E-Class?
No, it is not suitable. The W214 is the next-generation E-Class launched in 2023, with a completely different chassis structure, suspension geometry, and strut mounting dimensions. Parts are not interchangeable with the W213.
