Torque rod bushings are installed at both ends of the torque rod, connecting the axle to the chassis. In the HINO 700 suspension system, they endure extremely high loads and dynamic impacts.
During acceleration, braking, and hill climbing, the axle generates torsional force and forward/backward displacement.
The rubber damping layer inside the bushing absorbs shear deformation, ensuring proper axle alignment and preventing excessive movement.
The bushing stabilizes axle positioning so that the suspension geometry remains constant under load.
Proper geometry reduces driveline vibration, universal joint wear, and noise.
The elastic rubber layer filters road impacts and high-frequency vibration, reducing metal-to-metal contact and enhancing ride comfort and durability.
In short:
A torque rod bushing is a dynamic stabilizer of axle positioning, driveline integrity, and suspension comfort.
OEM reference S40J9-E0190 is widely used across the HINO 700 series (exact position depends on the axle configuration).
Specially formulated rubber for high fatigue resistance
Thick-walled steel sleeves for high torsional loads
Integrated vulcanized bonding for superior durability
Designed for heavy-duty and rough-road environments
Common equivalents include:
S40J9-E0190
S40J9-E0191
Other regional HINO 700 torque rod bushings
Advantages of the Huami version:
Enhanced rubber thickness
Higher bonding strength than standard aftermarket bushings
Excellent resistance to oil, ozone, heat, and abrasion
Longer life under heavy-duty or mining conditions
A torque rod bushing consists of three main components:
Material: Alloy steel / high-carbon steel
Function: Mounting interface with the chassis or torque rod bolt
Requirements: High strength, toughness, and precise inner diameter
Material: Seamless thick-wall steel tube
Function: Press-fit into torque rod housing
Requirements: High roundness, strong compression resistance
This is the functional core of the bushing.
Material options include:
NR (Natural Rubber): Best elasticity & fatigue resistance
NBR: Excellent oil and grease resistance
EPDM: Superior ozone, aging, and heat resistance
Hardness: 65–80 Shore A
Operating Temperature: –40°C to +120°C
Oil Resistance: High (NBR-based compounds)
Abrasion Resistance: 20–30% higher than standard aftermarket bushings
Because torque rod bushings are wear items, regular inspection is essential.
A worn bushing cannot restrain torsion and movement, causing the axle to shift.
Indicates severe rubber cracking or complete debonding, allowing metal-to-metal contact.
Often caused by:
Continuous heavy load
High temperature exposure
Oil contamination
Poor-quality rubber
Visual Inspection: Look for cracks, tears, or separation
Lever/Pry Test: Check for inner/outer sleeve movement
Loaded Test: Apply force while lifted to detect excessive movement
If any of these symptoms appear, a torsional bushing replacement should be performed immediately.
Proper installation is crucial to bushing life and suspension stability.
Use a hydraulic press and proper tooling
Do NOT hammer the bushing
Ensure press direction matches OEM orientation
Avoid damaging rubber or deforming the outer sleeve
The inner and outer sleeves must remain perfectly concentric
Misalignment will cause premature tearing
First inspection after 500–1000 km
Recheck during every major service interval
