4880-10 Isuzu NPR NQR N4000 – CBIN4000 SUPPLIED WITH NO BRACKET Bearing ID: 1.575″ – 40MM

Important: The 4880-10 is supplied as the bearing assembly only -- no bracket is included. The Isuzu NPR, NQR, and N4000 platforms use a proprietary bracket configuration that varies between wheelbase and body configurations. Ordering this bearing assumes you are retaining the original bracket and replacing only the bearing and rubber isolator unit.

Bore dimension is 40mm, which converts to 1.574 inches -- the same nominal bore used across the 1350/1410-series domestic applications. Isuzu's medium commercial trucks use metric dimensioning throughout the drivetrain, so the 40mm designation is the primary spec; the 1.574-inch equivalent is provided for cross-reference convenience when sourcing alongside U-joints or other SAE-spec components in a complete rebuild.

• SKU: 4880-10
• Application: Isuzu NPR, NQR, N4000 (CBIN4000)
• Inner Bore: 40mm / 1.574 inches
• Bracket: Not included -- source separately or reuse OE bracket

When sourcing a replacement bracket, measure the NPR/NQR tunnel mounting pattern carefully. Isuzu commercial trucks have gone through multiple driveshaft configurations across production years, and bracket hole spacing has changed between generations. If reusing the original bracket, inspect it for cracks or elongated mounting holes before reinstalling -- a damaged bracket will allow the bearing to bounce and will transmit driveline vibration directly into the cab structure.
