Suspension & Steering Parts for 2014 Mercedes-Benz E: A Complete Replacement Guide

The 2014 Mercedes-Benz E-Class is known for its smooth ride and precise handling, but like any vehicle, its suspension and steering components wear over time. Replacing these parts promptly is essential to maintain comfort, safety, and alignment. This guide covers the most common parts that need attention, how to recognize failure, and what to consider when choosing replacements.

Common Suspension & Steering Parts for the 2014 Mercedes-Benz E

The suspension and steering system on the 2014 E-Class (W212 chassis) includes several wear-prone components. The most frequently replaced parts include:

Control Arms and Ball Joints

• Front upper and lower control arms – These connect the wheel hub to the frame and allow vertical wheel movement. The ball joints at the ends wear out, causing clunking noises and loose steering.
• Rear control arms – The multi-link rear suspension uses multiple arms that can develop worn bushings or ball joints, leading to rear-end instability or uneven tire wear.

Sway Bar Links and Bushings

• Front and rear sway bar links – These small links connect the sway bar to the suspension. When worn, they cause a knocking sound when driving over bumps or during turns.
• Sway bar bushings – Rubber bushings that hold the sway bar to the subframe. Deterioration can cause excessive body roll and noise.

Shock Absorbers and Struts

• Front struts (if Airmatic) or conventional shocks – The E-Class may have standard coil springs or the AIRMATIC air suspension. Air springs can leak, and shock absorbers lose damping ability over time.
• Rear shocks – Similar wear characteristics; sagging or bouncy ride indicates replacement is needed.

Steering Components

• Tie rod ends – Inner and outer tie rods connect the steering rack to the wheels. Worn tie rods cause play in the steering wheel, wandering, and uneven tire wear.
• Steering rack – Though less common, leaks or internal wear can cause stiff steering or fluid loss.
• Steering damper – Some E-Class models have a steering damper to reduce vibration. A leaking or worn damper can cause steering shimmy.

Bushings and Mounts

• Subframe bushings – Isolates the subframe from the chassis. Worn bushings can cause clunking and misalignment.
• Strut mounts – Rubber mounts that connect the strut to the chassis; cracked mounts lead to noise and reduced damping.

Signs That Suspension & Steering Parts Need Replacement

Watch for these warning signs that indicate worn components:

• Noises: Clunking, popping, or creaking when going over bumps or turning.
• Vibrations: Steering wheel shakes or shimmy at highway speeds.
• Uneven tire wear: Feathered or cupped edges, especially on the inner or outer treads.
• Vehicle pulls to one side: The car drifts even when the steering wheel is straight.
• Loose steering: Excessive play in the steering wheel, wandering, or delayed response.
• Leaking fluid: Visible oil or air suspension fluid on shocks or steering rack.
• Sagging or nose diving: Vehicle sits lower than normal or dips sharply during braking.

If you notice any of these symptoms, inspect the affected area or have a mechanic diagnose the specific part. Replacing worn components as a set (e.g., both front control arms) is often recommended to maintain balanced handling.

OEM vs. Aftermarket Parts: Which Should You Choose?

When replacing suspension and steering parts on a 2014 Mercedes-Benz E, you have several options:

Original Equipment Manufacturer (OEM) Parts

OEM parts are made by the same suppliers that manufactured the original components for Mercedes. They are identical in design and quality to what came on the car.

• Pros: Perfect fit, reliability, and often a warranty (typically 1-2 years). No guesswork.
• Cons: Higher cost. For example, a front control arm assembly can cost $200–$400.
• Best for: Owners who want guaranteed performance and plan to keep the car long-term.

Premium Aftermarket Brands (e.g., Lemförder, TRW, Febi Bilstein)

These brands supply OEM parts to Mercedes and also sell under their own name. They offer the same quality as OEM at a slightly lower price.

• Pros: High quality, often better corrosion protection, and lower cost (10–30% savings).
• Cons: Not all parts are identical; some may differ slightly in finish or bushing material.
• Best for: Value-conscious owners who still want OE-level quality.

Budget Aftermarket (e.g., Sidem, Vaico, URO)

Budget brands offer lower prices but may use cheaper materials or less rigorous testing.

• Pros: Low cost – a control arm might be under $100.
• Cons: Shorter lifespan, potential fitment issues, increased noise or vibration.
• Best for: Short-term ownership or tight budgets, but expect to replace sooner.

Replacement Intervals and Cost Considerations

Most suspension and steering parts on the 2014 E-Class should be inspected around 60,000–80,000 miles, with replacement typically needed between 80,000 and 120,000 miles. However, driving conditions (rough roads, heavy loads) can accelerate wear.

Typical costs for parts (excluding labor) in the US market:

• Front control arms (lower/upper): $150–$400 each (OEM) or $80–$150 each (aftermarket).
• Ball joints: $30–$80 each (but often sold with control arms).
• Tie rod ends: $40–$100 each.
• Shocks/struts: $100–$300 each for conventional; air suspension struts $400–$800 each.
• Sway bar links: $20–$50 each.
• Bushings: $15–$50 each (if sold separately).

Labor for replacing these parts can range from $100–$200 per corner for simple items (links, tie rods) to $300–$500 for control arms or struts that require alignment. A full front suspension overhaul (control arms, shocks, links) might cost $1,500–$2,500 including parts and labor.

Final Recommendation

For most 2014 Mercedes-Benz E-Class owners, the best balance of quality and value is to use premium aftermarket brands like Lemförder, TRW, or Febi Bilstein for suspension and steering parts. They deliver OEM-level fit and durability at a lower price point. Replace components in pairs (both front control arms, both rear tie rods) to ensure even wear and handling. Always have a professional alignment performed after replacing any suspension or steering component to avoid tire wear and drivability issues. If cost is not a concern and you want absolute peace of mind, choose genuine Mercedes-Benz OEM parts. Avoid the cheapest aftermarket options unless the car is near the end of its service life.

By addressing worn suspension and steering parts promptly, you can restore the precise handling and comfortable ride that the 2014 E-Class is known for.
