Detailed Description

Timken 710480 is a differential pinion seal designed for rear axle service where reliable lubricant retention is critical. Its sealing profile is engineered to help maintain proper differential lubrication, while the reinforced case and ribbed inner diameter support a secure fit on the spindle surface.

• Heat-related seal wear from poor lubricant circulation
• Sealing issues caused by minor spindle surface imperfections
• Noise or driveline concerns related to low differential fluid level

Installation Notes and Tips

Confirm axle type, position, and vehicle application before installation. Clean the sealing surface thoroughly and inspect the pinion yoke or spindle for wear, grooves, or damage that could affect sealing performance.
