Detailed Description

Timken B2012 is a precision bearing used in transfer case and driveline service where accurate shaft support and smooth rotation matter. Its dimensional specs make it a strong match for applications calling for a 31.75 mm bore, 38.10 mm outer diameter, and 19.05 mm width. This part number appears across many 1980-2002 truck and SUV platforms, including Ford F-250, Ford F-350, Chevrolet K1500, GMC K3500, and Jeep Cherokee transfer case applications.

For buyers searching for a Timken B2012 transfer case bearing, this part is commonly referenced in Warner 1345, 1356, 1370, 4401, 4407, and 4470 transfer case service, as well as New Process 208, 219, 228, and 229 applications. It is also listed for several Chevrolet and GMC front inner and front outer differential-related service positions where the same bearing dimensions are used.

What It Helps Address

• Excessive shaft play in the transfer case output area
• Noise caused by worn or rough bearing surfaces
• Vibration from poor shaft support
• Wear from degraded OE bearing dimensions
• Service replacement for high-mileage driveline components

Installation Notes and Tips

Verify the bearing dimensions and transfer case code before installation. Confirm the application by year, make, model, position, and transfer case designation, especially on Ford F-250, Chevrolet K1500, and GMC K3500 platforms where multiple transfer case variants are listed. Clean the bore and shaft surfaces thoroughly, and inspect related seals and mating components for wear before assembly.

Quality Assurance

Timken tests bearing design, materials, and manufacturing processes to support consistent performance. The B2012 is backed by Timken’s long OE supply history and is engineered to meet or exceed original equipment bearing performance requirements.
