DZ15221435116 Leaf Spring Bushing Fitment and Replacement Guide

To confirm whether a DZ15221435116 leaf spring bushing fits your vehicle, verify the complete part number against the vehicle’s axle and suspension application, then compare the original bushing’s key dimensions and construction. Do not rely on a model name alone: vehicle versions and suspension configurations can differ. Before replacement, check the bushing and surrounding mounting points for wear or damage, and follow the vehicle manufacturer’s service procedure for removal and installation.

This guide is for truck parts buyers, fleet maintenance teams, repair shops, and distributors who need to identify the correct bushing and plan a replacement. At Shengfan, we recommend confirming application details before ordering so that the supplied part can be checked against the buyer’s requirements rather than selected by part number alone.

Key Takeaways

Use DZ15221435116 as an identification starting point, not as the only fitment check.
Confirm the vehicle and suspension configuration, then compare the removed part or reliable technical documentation.
Record the bushing’s inner diameter, outer diameter, and width in millimeters for a practical dimensional comparison.
Use suitable workshop equipment and the correct service information; do not guess installation orientation or fastener torque.
Ask the supplier to confirm the applicable part details, order conditions, and current lead time before placing a purchase order.

What the Leaf Spring Bushing Does

A leaf spring bushing is fitted at a spring mounting point to provide a controlled interface between the spring eye or suspension link and its bracket or pin. Depending on the design, it can help reduce direct metal-to-metal contact and limit vibration transfer through the suspension. Its position and construction affect how the spring assembly moves as the vehicle travels over changing road surfaces.

A bushing that is worn, damaged, or incorrectly matched may contribute to noise, looseness, uneven movement, or abnormal wear around the mounting area. These signs are not proof that the bushing is the only cause: a worn pin, damaged bracket, loose fastener, or other suspension fault can produce similar symptoms. Inspect the complete mounting assembly before deciding which parts to replace.

Fitment: How to Confirm DZ15221435116

Start with the full vehicle and part details

Record the vehicle make, model, year or production period, axle configuration, and the suspension position where the bushing is installed. If the part is being considered for a Shacman F3000, treat that model reference as a clue rather than definitive confirmation; variants and component specifications should still be checked. Where available, use the vehicle’s parts documentation or ask a qualified parts specialist to verify the application.

Check the full number, including every letter and digit, against the marking on the old part, packaging, or an established parts record. Similar-looking numbers can refer to different components, and an incorrect transcription can lead to a wrong order. If the original bushing has no readable marking, use its position, dimensions, and construction alongside the vehicle information.

Compare the original bushing’s key dimensions

If you have the removed part, record three measurements in millimeters: inner diameter (ID), outer diameter (OD), and overall width. Compare each measurement with an approved drawing, sample, or supplier-confirmed specification; a close visual match is not enough to establish interchangeability. Also note any shoulder, sleeve, flange, offset, or other feature that affects how the bushing sits in the spring eye or bracket.

Measurements from a damaged or heavily worn part may not represent its original dimensions. When possible, compare them with a new reference part or technical documentation, and use suitable measuring tools. Do not force a bushing into a mounting point to test fit, because an incorrect size or installation method can damage the component or surrounding hardware.

Check material and construction

Leaf spring bushings may use rubber-based elastomer, sometimes combined with an inner sleeve or other structural features. The correct material and construction depend on the intended application and the design of the suspension assembly. Do not assume that a different material is a direct substitute simply because its dimensions appear similar.

Shengfan contains other products and information you need, so please check it out.

Confirm whether the required part is supplied with a sleeve, whether the sleeve is separate, and whether the bushing has a specified orientation. If your application requires a particular compound, hardness, or construction, provide the requirement or reference drawing when requesting a quotation. Shengfan can review the information provided and clarify which product details need confirmation before an order is finalized.

Replacement Process: Practical Checks

1. Prepare safely and confirm the service procedure

Park the vehicle on a firm, level surface, secure it against movement, and use lifting and support equipment rated for the vehicle and suitable for the work. Suspension components can carry stored load, so do not remove a spring pin or mounting fastener without following the vehicle manufacturer’s instructions. If you are not trained or equipped for this repair, use a qualified commercial-vehicle workshop.

2. Inspect before removing parts

Identify the exact bushing position and note its orientation before disassembly. Inspect the spring eye, pin, bracket, and fasteners for visible wear, deformation, corrosion, or damage that could affect the replacement. Photographing the assembly before removal can help with orientation checks, but it does not replace the service documentation.

3. Remove and compare the old part

Use an appropriate removal method and press equipment where the design requires it; avoid uncontrolled impacts that may deform the spring eye or bracket. Once removed, compare the old component with the replacement by part marking, dimensions, sleeve arrangement, and profile. Stop if the replacement differs in a way that could affect seating or movement, and seek confirmation rather than modifying the part to make it fit.

4. Install and inspect the replacement

Follow the specified installation direction and method for the vehicle and bushing design. Refit or replace associated hardware as required by the service procedure, and tighten fasteners to the manufacturer’s stated torque and sequence; we do not recommend using a guessed value. After installation, inspect seating and alignment, then complete any post-repair checks required for the vehicle.

Common Fitment and Replacement Mistakes

Ordering by model name alone: A vehicle family can include different suspension or axle configurations. Confirm the specific application and mounting position.
Ignoring dimensions: A matching part number should still be checked against reliable application information, especially when the old component or packaging is uncertain.
Overlooking related wear: A new bushing cannot correct a damaged spring eye, worn pin, or distorted bracket. Inspect the complete connection.
Assuming all rubber bushings are equivalent: Material and construction can affect fit and operation. Verify the intended specification rather than selecting by appearance.
Guessing installation details: Incorrect orientation, pressing technique, or fastener torque can create problems. Use the vehicle’s service instructions and appropriate workshop tools.

How to Evaluate a Supplier and Plan an Order

For a reliable sourcing decision, ask the supplier to confirm the part number, intended application, dimensions, material or construction details, and any included sleeve or hardware. Provide clear photos, the vehicle and axle information, and measurements where available. This gives both sides a stronger basis for checking fitment than a brief request containing only a model name.

Price, minimum order quantity (MOQ), and lead time depend on the product specification, order volume, stock status, and shipping destination. Request these terms in writing for the quantity and delivery location you actually need, and clarify whether the quotation is based on a standard item or a particular drawing or sample. At Shengfan, we welcome B2B inquiries for DZ15221435116 Leaf Spring Bushing and can review the application details shared with us before discussing supply options.

Conclusion: Confirm First, Then Replace

The dependable way to confirm DZ15221435116 fitment is to verify the full part number against the vehicle and suspension application, then compare the original or documented component’s dimensions and construction. For a practical check, record the inner diameter, outer diameter, and width in millimeters, while also noting sleeves, shoulders, and orientation. If any detail is uncertain, pause the order or installation until the application is confirmed.

Before requesting a quotation from Shengfan, prepare the part number, vehicle and axle details, installation position, available measurements, and photos or a drawing if possible. Ask for confirmation of the product specification, MOQ, price basis, and current lead time. This gives your purchasing team a clear next step and helps reduce avoidable fitment and replacement risk.
