Mercedes-Benz A-Class Front Suspension Strut: OEM Part Number
| Standard strut, right | Genuinely a different part number from the left-side strut — not a mirror-image of the same component |

| 4MATIC (AWD) strut, where fitted | A genuinely different reference from the front-wheel-drive strut, reflecting the different front driveline layout |
Mercedes-Benz A-Class Front Suspension Strut: The System That Quietly Does All the Work
On the Mercedes-Benz A-Class, these components absorb every pothole, bump and cornering force before any of it reaches the cabin, which is why deterioration here rarely announces itself with one obvious symptom. Working through it methodically finds the actual cause faster than guessing ever will.
Mercedes-Benz A-Class Front Suspension Strut: What It Does
The Mercedes-Benz A-Class's front strut does two jobs in one unit — damping the suspension's movement and providing the coil spring's mounting point. Wear here shows up as excessive bounce after bumps rather than a quick settle, and left long enough, uneven tyre wear tends to follow.

A Genuinely Important Finding Worth Knowing — Mercedes-Benz A-Class Front Suspension
If a knocking or creaking noise has developed from the front suspension, particularly noticeable when coming off the accelerator or over a slight dip in the road, this is genuinely worth knowing: a modified top bearing for the front struts genuinely exists and has been fitted by Mercedes to address exactly this fault. In at least one documented case, this didn't just cure the knock, it also stiffened up the suspension and noticeably improved the car's overall handling — worth asking a dealer specifically whether this revised bearing has been fitted to your car, or whether it's available to address a persistent knock.
It's also genuinely worth knowing a useful diagnostic technique: with the road wheel removed, checking whether the gaiter and attached bump stop are loose rather than securely fitted at the top of the shock absorber's piston is a simple test worth trying.
