Mercedes-Benz Truck Bushing — OEM: 0003250985

1. What Does a Mercedes Truck Bushing Do? 

In the suspension and chassis system of Mercedes-Benz trucks, a rubber-metal bushing (Rubber-Metal Bushing) is a high-load, high-cycle, highly coupled component. One side connects to the axle/links/control arms, and the other side interfaces with the frame or bracket through a compliant joint. For heavy-duty trucks, a bushing is not just a “connector”—it’s a motion controller.

1.1 Absorbs road and axle vibration & impact

Heavy loads, potholes, speed bumps, long-term gravel roads and harsh duty cycles generate large impacts and high-frequency vibration at the axle side. The elastomer layer converts vibration energy into heat and attenuates it, reducing transmission to the frame and cab—improving ride comfort and extending component life. This is exactly why buyers search Mercedes-Benz suspension bushing: to reduce vibration and shock transfer.

1.2 Stabilizes suspension and chassis geometry

Within its designed elastic range, a bushing allows controlled compliance while limiting abnormal movement. It helps maintain suspension geometry (e.g., toe/camber behavior) and improves stability during cornering, braking dive, and emergency lane changes. For fleets, stability means less wandering, less uneven tire wear, and lower operating costs.

1.3 Prevents metal-to-metal contact, reducing wear and noise

Hard metal-to-metal joints accelerate wear, ovalize holes, create clunks, and loosen over time. A bushing replaces hard friction with elastomer compliance and controlled shear/rotation—significantly reducing NVH sources such as squeaks and clunks.

1.4 Critical under heavy-load, long-haul, high-frequency conditions

Models like ACTROS and AROCS often operate in long-haul, mining, port and construction environments. Once a bushing cracks or debonds, it can trigger a chain reaction: geometry drift → tire wear → reduced steering/braking stability → secondary damage to links, pins and brackets. It’s a “low unit cost, high failure cost” part.

2. OEM 0003250985 Overview

• OE/OEM: 0003250985

• Common formats: 000 325 09 85 / 0003250985 

2.2 Interchange / replacement relationship

This part is commonly used as an aftermarket replacement for:

• 0003250485

• A0003250485

• A0003250985
  Because many buyers search by interchange numbers (e.g., A0003250485), listing both OE and interchange numbers helps capture high-intent search traffic.

2.3 Key dimensions for quick verification

• Height (H): 170 mm

• Inner Diameter (ID): 107 mm

• Outer Diameter (OD): 154 mm

Note: Design variants may exist by model year or suspension configuration. Final confirmation should be done via drawing/sample and installation position. Hebei Huami supports matching and optimization based on dimensions and fitment requirements.

2.4 Applicable Mercedes-Benz truck models

• ACTROS MP2 / MP3 

• ANTOS

• AROCS

• ACTROS

• ATEGO

• AXOR 2

• ZETROS

2.5 Typical installation positions 

Rubber-metal bushings like this are commonly found at:

• Suspension links / torque rods / radius rods

• Axle-to-link connection points

• Stabilizer bar, control arm, or bracket interfaces
  Its core role is to balance load support + guidance + vibration damping.

3. Structure & Material Analysis 

3.1 Structure: inner sleeve, outer sleeve, elastomer layer

• Inner sleeve: interfaces with bolt/pin; carries clamp force and shear load

• Outer sleeve: press-fit or matched to the housing/bore

• Elastomer layer: provides damping, compliance and fatigue durability

3.2 Rubber compound options 

Hebei Huami can tailor compounds based on duty cycle and environment:

• NR (Natural Rubber): excellent resilience and fatigue resistance for dynamic loads

• NBR: improved oil resistance for oily/contaminated environments

• EPDM: strong weather/ozone/aging resistance for outdoor exposure and temperature swings
  (Custom blends and heavy-duty reinforced versions are available.)

3.3 Shore A hardness (customizable)

• Typical range: 55–80 Shore A (optimized based on load and NVH targets)
  Too hard can increase vibration transmission; too soft may cause geometry drift and early wear. Compound and structure should be optimized together.

3.4 Key performance targets

• Abrasion and tear resistance for rough roads and impact loads

• Oil resistance for maintenance/road contamination

• Weather/ozone resistance for outdoor exposure

• Fatigue resistance under combined shear + compression cycles

3.5 Metal corrosion protection (coating/plating)

Anti-corrosion treatment improves long-term reliability and prevents “seized” assemblies or removal issues:

• Plating (e.g., zinc systems)

• Coating/painting (selected per salt-spray requirement)

3.6 Why bonding & vulcanization matter

Real durability is often decided by the bonding system and process window control:

• Consistent surface preparation (cleaning, roughening, primer/adhesive system)

• Stable vulcanization temperature/time profile

• Bond strength and fatigue debonding control
  This reduces common failure modes like debonding, off-center wear, and early noise.

4. Common Failure Modes & Symptoms 

Typical issues that lead buyers to search Mercedes truck bushing or 0003250985 include:

• Chassis clunking / abnormal noise: “clunk” over bumps; more obvious during start/stop/braking

• Loose suspension feel: increased play and instability

• Pulling / wandering: geometry drift affects straight-line tracking

• Abnormal tire wear: inner/outer edge wear or sawtooth wear

• Cracking / debonding / off-center wear: visible rubber cracks or separation at the rubber-metal interface

Quick checks to confirm replacement need

Visual inspection (cracks/debonding/off-center), pry-bar check for abnormal movement, road test for noise/wobble, plus tire wear pattern and alignment data where available. If looseness is evident, inspect related links/fasteners to avoid repeated comebacks.

5. Installation & Maintenance Guide 

5.1 Removal and press-fitting precautions

• Use proper pressing tools; avoid hammering that damages sleeves or rubber

• Clean and de-rust the housing bore; ensure stable interference/fit

• Avoid lubricants/chemicals contaminating bonding areas (choose assembly aids per process requirements)

5.2 Alignment and orientation

Some bushings are directional. Follow markings and orientation requirements—wrong orientation can drastically shorten service life.

5.3 Bolt torque requirement (placeholder)

• Torque: ____ Nm (follow Mercedes service manual / model-specific spec)
  Tip: Many bushings should be final-torqued at normal ride height to avoid pre-twisting the rubber.

5.4 Recommended inspection & re-torque cycle

Include in fleet maintenance routines: post-install re-check after initial operation, then periodic inspections based on duty cycle and road conditions.

5.5 Practical tips to extend bushing life

Avoid overload and continuous high-impact operation; keep chassis free of oil/corrosion sources; inspect links/pins/brackets together to prevent “new bushing in worn housing” looseness.
