Detailed Description

SKF BR3780 is engineered for transfer case output shaft bearing service where precise fit and stable rotation matter. The tapered roller construction supports the loads found in driveline operation, while the 2.000-inch inside diameter and 1.187-inch width help ensure correct dimensional match for the application. This part cross-references Dorman - HELP 15791 for the same application. Compatible with Hummer H1 transfer case service, the BR3780 is also listed for Four Seasons 157351 and other interchange numbers including 1458BR3780 and 01724N.

For Hummer H1 owners searching for a transfer case output shaft bearing, SKF BR3780 provides a technical replacement option for front outer and rear outer positions. It is a practical choice when servicing driveline noise, bearing wear, or transfer case rotation issues on 2002-2004 and 2006 Hummer H1 models.

Common Issues This Bearing Can Address

• Transfer case bearing noise during acceleration or deceleration
• Excessive play at the output shaft
• Rough or uneven shaft rotation
• Wear-related driveline vibration
• Damage from contaminated or degraded bearing surfaces

Installation Notes and Tips

Verify the bearing dimensions before installation: 2.000-inch inside diameter and 1.187-inch width. Inspect the output shaft, races, and surrounding transfer case components for scoring, heat damage, or contamination before assembly. Proper bearing preload and clean lubrication are important for long service life. Confirm the vehicle position before ordering, as this part is listed for Hummer H1 front outer and rear outer applications.
