Overview

InMotion WS711030 is a rear differential pinion seal built for applications that need a precise sealing surface and dependable contamination control. It uses PTFE material to help maintain a tight barrier against moisture and debris in the differential assembly.

Compatible with a wide range of Chrysler, Dodge, Jeep, Ram, and Volkswagen rear differential applications, this seal is a fitment-based replacement for vehicles such as the Chrysler 300, Dodge Charger, and Jeep Grand Cherokee. The WS711030 part number is also useful when matching the correct seal for service work on the rear differential pinion area.

Key Features

• PTFE construction for low-friction sealing performance.
• Precision dimensions for the differential pinion shaft interface.
• Helps block contaminants that can affect internal differential components.
• Supports leak control in rear differential service applications.
• Fits a broad range of rear-position applications across multiple platforms.

Detailed Description

The InMotion WS711030 differential pinion seal is engineered for rear axle service where a secure seal is critical to differential protection. Its PTFE material and measured inside diameter of 3.657 inches are specified to match the shaft interface and maintain sealing integrity under operating conditions. This part number, WS711030, applies to rear differential applications on Chrysler 300, Dodge Charger, and Jeep Grand Cherokee models, along with additional Chrysler, Dodge, Jeep, Ram, and Volkswagen vehicles listed in the fitment data.
