Detailed Description
FSFT 2020639 is a driveline and axle component used in differential service where ring-and-pinion gear replacement is required. Compatible vehicle coverage includes 2004-2012 Chevrolet Colorado rear, 2004-2012 GMC Canyon rear, 2006-2010 Hummer H3 rear, 2009-2010 Hummer H3T rear, 2003-2008 Isuzu Ascender rear, and additional rear or N/A-position applications across Chevrolet, GMC, Oldsmobile, Pontiac, Buick, and Isuzu platforms. For buyers searching for a Chevrolet Colorado rear differential ring and pinion, GMC Canyon rear gear set, or Hummer H3 rear ring and pinion, this listing provides the fitment detail needed to match the application.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Is Used For
- Restoring proper differential gear operation after gear wear or damage
- Addressing gear noise caused by worn ring and pinion teeth
- Correcting driveline issues related to final-drive gear failure
- Supporting rear differential rebuilds on listed trucks, SUVs, and cars
Installation Notes
Verify axle type, gear ratio, and exact vehicle application before installation. Differential ring and pinion replacement requires careful setup of backlash, pinion depth, and bearing preload, so professional installation is recommended. Match the listed position exactly: rear for truck and SUV applications, and N/A-position listings for the specified passenger car platforms.
Quality Assurance
FSFT 2020639 is cataloged for direct application matching across the listed vehicles and positions. Confirm fitment against the vehicle year, make, model, and rear differential configuration before ordering.
