Mercedes-Benz trucks use multiple linkages—control arms, torque rods, stabilizer bars, trailing arms, etc.—to locate the axle and manage suspension motion. A Rubber-Metal Bushing acts as an “elastic joint” between metal components, delivering four key benefits:
When a heavy truck hits potholes, speed bumps, or broken pavement, shock loads travel from the wheel end to the chassis. The rubber damping layer converts part of that energy into heat, reducing peak impact transmission. In fleets running high payloads or harsh routes (construction, mining, regional roads), bushing dynamic stiffness and damping are essential for durability and driver comfort.
Wheel alignment and axle location depend on how suspension joints deflect under load. Proper bushing stiffness keeps geometry controlled while still providing isolation:
Too soft: geometry drift increases → wandering, loose handling, accelerated tire wear
Too hard: impact passes through → harsher NVH, more stress on brackets and arms
A quality Mercedes-Benz suspension bushing is therefore not just “rubber”—it is a key tuning element for chassis geometry stability.
Without elastic isolation, metal-to-metal micro-motion leads to fretting wear, noise, bolt loosening, ovalized holes, and corrosion. Bushings spread loads and reduce contact stress, helping extend the life of torque rods, arms, and chassis brackets.
Fleet operators care about predictable handling, reduced downtime, and lower lifetime cost. A well-designed Mercedes truck bushing improves:
Straight-line stability at highway speeds
Braking stability and reduced axle steer
Reduced vibration/noise transfer to the cab
Better durability in repeated load cycles
OEM: 9463900050 is a truck suspension/chassis rubber-metal bushing used on Mercedes-Benz trucks (exact fitment depends on model/platform and axle/suspension configuration). For B2B procurement, core selection factors are: correct dimensions, rubber compound choice, bonding durability, corrosion protection, and batch consistency.
System: Mercedes-Benz Trucks suspension / chassis
Common installation locations (examples): suspension links, torque rods, control arms, stabilizer bar joints (varies by model)
Cross reference / alternative part numbers (placeholder): Provide your drawing/sample/VIN/axle type to confirm: [To be added]
Fitment note: Mercedes truck platforms can vary widely. To avoid press-fit interference or premature failure, confirm with OEM number + photos + key dimensions (ID/OD/length/shoulder).
A reliable truck rubber bushing replacement requires optimized design plus controlled materials and process parameters.
Most rubber-metal bushings include:
Inner sleeve: interfaces with bolt/shaft; transfers clamp load and shear
Outer sleeve: press-fits into housing; provides locating boundary
Elastomer layer: controls static stiffness, dynamic stiffness, damping, and fatigue life
Depending on application, features like shoulders, voids, grooves, or limit stops may be used to tune directional stiffness and durability.
To match heavy-duty truck operating conditions (load cycles, water/mud, salt, oils, temperature swings), we offer compound options including:
NR (Natural Rubber): excellent rebound and fatigue performance; strong dynamic durability
NBR (Nitrile Rubber): improved oil resistance; ideal when oil contamination is likely
EPDM: strong ozone/weather resistance and heat aging performance; good for outdoor exposure and wide temperature ranges
Final compound selection is engineered according to target stiffness/damping, chemical exposure, climate, and cost requirements.
Typical development range:
Shore A: 55–80 (customizable)
Key properties for B2B buyers:
Abrasion & tear resistance: reduces off-center wear and crack propagation
Oil resistance: minimizes swelling and stiffness drift
Weathering resistance: ozone/UV/thermal aging protection
Compression set: helps prevent long-term “looseness” under constant clamp load
Truck undercarriage parts are exposed to water, mud, and salt. Anti-corrosion treatment improves long-term stability of the assembly and helps protect the bonding interface. Options include:
Surface cleaning/pre-treatment (shot blasting, phosphating, etc.)
Plating (e.g., zinc/zinc-nickel) or coating (paint/powder)
Selection is based on customer spec and target corrosion environment.
The bond between rubber and metal is often the “lifeline” of the bushing. Controlled bonding systems and vulcanization windows help prevent:
Early debonding
Post-salt-spray bond failure
Fatigue-driven peel growth under torsion/shear
Huami applies process control and bond-strength inspection to keep batch-to-batch consistency for distributor and fleet supply.
When users search “Mercedes truck bushing noise” or “truck rubber bushing replacement,” they usually already face symptoms. Typical failure patterns include:
Clunk/knock over bumps
Metallic tapping during steering or braking
Often caused by rubber fatigue cracks, debonding, or internal slip between sleeve and elastomer.
Highway wandering requiring constant correction
Pulling under braking or uneven tire wear
Softened bushings or off-center wear can allow geometry drift and axle steer.
Surface cracking (ozone/aging)
Rubber-metal separation (bond failure)
Shiny or localized wear marks (misalignment or uneven load)
Visual: cracks, debonding, rubber debris, corrosion expansion
Pry-bar check: abnormal free play at joints
Road test correlation: low-speed bumps, braking dive, turning noise
Left-right comparison: big differences indicate misload or installation issues
Correct installation is crucial to bushing durability—especially for heavy-duty Mercedes trucks.
Use proper pull/press tooling; avoid hammering that can deform the outer sleeve
Clean the bore; remove burrs and corrosion
Use approved assembly lubricant only if specified by service manual (avoid chemical attack on rubber)
If the bushing has an orientation mark, install exactly as specified
Ensure coaxial press-fit to avoid early eccentric wear and debonding growth
Follow Mercedes service manual requirements: [Torque spec to be added]
Important practice: Many suspension bushings should be finally tightened at normal ride height to avoid rubber pre-twist and fatigue.
Post-install check after 500–1000 km (fleet standards may vary)
Routine service inspections: noise, cracks, geometry drift, fastener status
Avoid chronic overload and harsh impact driving
Fix alignment issues early (tire wear is a strong indicator)
Replace bushings in axle sets where appropriate
