cciyu Driveshaft Center Support Bearing for Nissan 720/D21 1986–1994 — OE 8473 Direct-Fit, Vibration-Reducing

CCIYU driveshaft center support bearing designed to replace the factory unit on select Nissan 720, D21, Frontier and Pathfinder models, restoring smooth driveline support and reducing vibration. This replacement center support bearing fits a wide range of Nissan pickups and SUVs from the mid-1980s through the early 2000s. Manufactured to meet or exceed the OE 8473 reference, the part is intended for installations where the original bearing shows wear, noise, or looseness. CCIYU engineered the bearing for dynamic load adaptation and multi-directional force control to help the driveshaft maintain alignment under driving loads.

Which Nissan models and years will this bearing fit?

The CCIYU bearing is compatible with many Nissan pickups and SUVs across specific model years and trims. It covers Nissan 720/D21 series, Frontier generations, and multiple Pathfinder trims listed in the fitment details. Always verify your vehicle’s model year, cabin configuration, and OE number before ordering to ensure correct compatibility.

• Fits: Nissan 720/D21 (1986–1994), multiple Frontier models (1998–2004), Pathfinder (1986–1995).
• Includes XE, SE, SC, SVE, LE, Base and other listed trims where applicable.
• OE reference: 8473 — check against your vehicle’s factory part number.

How does this center support bearing affect drivability and vibration?

Replacing a worn center support bearing restores stable driveline behavior and reduces the vibration transferred into the cabin. The bearing’s design compensates for changing loads and minor misalignment, helping the driveshaft rotate smoothly and lowering noise. This contributes to improved handling feel and a quieter ride during acceleration and cruising.

• Dynamic load adaptation minimizes transmission of shock loads to the drivetrain.
• Multi-directional force control resists shaft deformation and misalignment.
• Less vibration and noise compared with a degraded factory bearing.

What are the key technical features of the CCIYU bearing?

The CCIYU unit is built for the specific mechanical demands of driveshaft applications: robust inner race, durable rubber housing, and a precision-mounted bearing that handles radial and axial forces. Its construction aims to lower the chance of seizure or abnormal vibration under variable operating conditions. The part is intended as a direct-fit replacement when the OE number matches your vehicle.

• OE number: 8473 for direct-match verification.
• Engineered for dynamic load adaptation during operation.
• Designed to withstand multi-directional forces typical of driveshafts.

Are there installation notes or fitment precautions I should know?

Proper fitment is critical: confirm vehicle year, model, trim, and OE part number before purchase. Incorrect installation or using the wrong part can cause driveline noise or damage. If you’re not experienced with drivetrain work, consider professional installation to ensure correct alignment and torque of mounting hardware.

• Verify compatibility against your vehicle’s OE number and model year.
• Inspect driveshaft and surrounding mounts during replacement for related wear.
• Recommend professional installation if unfamiliar with driveshaft procedures.

This CCIYU driveshaft center support bearing is for owners and technicians restoring driveline performance on older Nissan pickups and SUVs. It suits do-it-yourself mechanics replacing a worn bearing, restoration projects returning a vehicle to original drivability, and repair shops servicing Frontier, D21 or Pathfinder models. Confirm your vehicle’s exact model year and OE number before ordering to ensure you receive the correct direct-fit replacement.
