ISUZU Front Door Trim Pad 1-73338465-1 1733384651 for CXZ51K 6WF1
ISUZU Front Door Trim Pad 1-73338465-1 1733384651 Compatible with CXZ51K 6WF1 Truck — OEM Standard Interior Trim Panel
Product Overview
The ISUZU Front Door Trim Pad with OEM numbers 1-73338465-1 / 1733384651 is a precision-engineered replacement designed for ISUZU CXZ51K series heavy-duty trucks, compatible with 6WF1 diesel engines. This component is a key part of the vehicle's cab interior — the Front Door Trim Pad Assembly — installed on the inner side of the door, providing not only aesthetic enhancement but also a mounting base for window regulators, door lock controls, and other functional components.
Numbering Note: This product number is 1-73338465-1 / 1733384651. The series also includes 1-73338465-0 / 1733384650. Related numbers include 1-73337515-0 / 1733375150 (Left-Hand front door trim) and 1-73337514-0 / 1733375140 (Right-Hand front door trim). Please verify the specific number and left/right side based on actual vehicle configuration.
Working Principle
The front door trim pad is a core component of the cab interior, combining aesthetic decoration with functional integration. Its main functions include:
Interior Decoration: Enhances the visual appeal and quality of the cab interior, creating a comfortable driving environment.
Functional Integration: Provides mounting positions and structural support for power window switches, door lock controls, speakers, armrests, and other components.
Sound & Thermal Insulation: The sound-absorbing material and sealing structure inside the trim panel effectively isolate external noise and heat, improving cab quietness and comfort.
Protection: Protects the wiring harnesses and mechanical structures inside the door from environmental factors, while preventing direct contact between occupants and door metal components.

Installation Position: This is a Front Leaf Spring Shackle Bushing. Some sources describe it as a "front leaf spring bushing (with oil seals)".
Associated Components: When replacing the bushing, it is recommended to inspect the shackle pin for wear — replace if necessary.
Pair Replacement Recommended: Suspension bushings should be replaced in pairs (left and right) to ensure consistent suspension performance.
Installation Lubriion: Apply high-temperature grease to bushing and pin contact surfaces during installation to ensure smooth operation and reduce wear.
Professional Installation: The shackle bushing is a critical suspension component requiring leaf spring disassembly — professional installation is recommended.
