FAQ

What vehicles are compatible with the 9-1002-BL bushing?

The 9-1002-BL bushing fits a broad range of models that use standard leaf spring mounting points. It is commonly used in many American and Asian passenger cars and light trucks. Check your vehicle’s service manual for the OEM part number to confirm compatibility.

Do I need to apply additional grease during installation?

The bushing comes pre‑filled with high‑performance grease designed to stay in place for the life of the part. No extra grease is required unless you prefer to add a thin layer for extra protection.

How does polyurethane compare to rubber bushings?

Polyurethane offers superior wear resistance, higher load capacity, and better grease retention than typical rubber. It also provides a firmer ride feel while still dampening noise, making it ideal for performance‑oriented applications.

Can I install the bushing myself?

Yes, the bushing is designed for straightforward bolt‑on installation using standard tools. Ensure the mounting surfaces are clean, align the bushing with the leaf spring brackets, and torque the bolts to the manufacturer’s specifications.

What is the expected service life of this bushing?

When used under normal driving conditions and properly maintained, the polyurethane bushing can last 60,000 miles or more, significantly outlasting conventional rubber alternatives.
