Mercedes-Benz E-Class Front Suspension Strut: OEM Part Number

Accuracy note: genuinely worth knowing: E-Classs with self-levelling or air suspension (where fitted, usually higher trims) use an entirely different, more complex and expensive suspension system from the standard steel-spring setup — confirm which your car has before assuming standard replacement parts and costs apply.

Standard steel-spring strut, right	Genuinely a different part number from the left-side strut — not a mirror-image of the same component
Standard steel-spring strut, left	A genuinely different reference from the right-side strut above
4MATIC (AWD) steel-spring strut	A genuinely different reference from the non-4MATIC strut above, reflecting the different front driveline layout
AIRMATIC air strut, left/right	Genuinely a completely different suspension medium from the standard steel-spring strut — an air spring combined with the shock absorber in one assembly, not a stiffer version of the same part; left and right are separate, non-interchangeable references
AIRMATIC with ADS (Adaptive Damping System)	A further distinct variant again from base AIRMATIC — adds electronically controlled damping on top of the air spring, and is genuinely a different part from non-ADS AIRMATIC struts

Mercedes-Benz E-Class Front Suspension Strut: The System That Quietly Does All the Work

On the Mercedes-Benz E-Class, every pothole, bump and cornering load gets filtered through these parts long before it's felt inside the car, which is precisely why wear rarely shows up as one clean symptom. A methodical, process-of-elimination check tends to find the actual culprit much faster than guessing.

Before you buy: suspension components vary by trim, engine weight and whether your car has the standard or sport-tuned setup. Always confirm against your VIN before ordering.

Mercedes-Benz E-Class Front Suspension Strut: What It Does

The Mercedes-Benz E-Class's front struts fold two components into one: the damper and the coil spring's mount. A worn strut means the car keeps moving after a bump rather than settling promptly, and that lingering movement can accelerate uneven tyre wear over time.

Confirmed: A Genuine Technical Bulletin Worth Knowing About — Mercedes-Benz E-Class Front Suspension

If a dull thumping noise has developed from the front of the car on bumps, this is genuinely worth knowing: a confirmed technical service bulletin addresses exactly this symptom on related models, relating to the shock absorber and strut top mount bearings, which can corrode over time and stop turning freely.

A genuinely useful finding worth checking if a knock survives other repairs: torque arms are a known weak spot on related models, worth checking these specifically if a persistent front knock has already survived replacing anti-roll bar links and control arms.

It's also genuinely worth knowing a useful diagnostic technique: with the road wheel removed, checking whether the gaiter and bump stop are loose at the top of the shock absorber's piston is a simple test worth trying.
