Timken 710439 Rear Wheel Seal for Infiniti

Timken 710439 is a rear wheel seal built for select Infiniti applications, including the Q45 and J30. It is engineered to retain lubricant at the wheel end while helping block road debris and other contaminants from entering the sealing area.

Key Features

• Precision sealing design helps control grease and oil at the wheel end
• Reinforced outer case helps resist installation damage and improve durability
• Ribbed rubber inner diameter seals minor spindle imperfections and supports spindle seating
• Internal contamination exclusion system helps reduce debris intrusion that can lead to leakage
• Vent holes promote lubricant flow around the seal lip to help manage heat build-up
