Detailed Description

The InMotion WS99218 repair sleeve is used to renew the crankshaft sealing surface where the harmonic balancer rides. When the original surface becomes grooved or worn, the front seal can lose contact and allow oil to escape. This sleeve provides a repair path that avoids replacing the entire balancer assembly when the sealing surface is the primary issue. The part number WS99218 is listed for front-position applications across many Chrysler, Dodge, and Jeep vehicles, including Dodge Ram 2500, Dodge Ram 3500, Dodge D150, and Jeep Grand Cherokee.

This part cross-references National (e.g., 99187) for the same application.

What It Helps Solve

• Front crankshaft oil leaks from a worn harmonic balancer sealing surface
• Seal failure caused by grooves or scoring on the shaft
• Repeat leakage after front seal replacement when shaft wear remains
• Need for a cost-conscious repair instead of replacing the balancer assembly
• Fitment needs on older Dodge, Chrysler, and Jeep front engine applications

Installation Notes and Tips

Verify shaft diameter before installation and confirm the repair sleeve matches the measured sealing surface within the listed diameter range. Clean the crankshaft area thoroughly before installing the sleeve, and inspect the front seal and harmonic balancer for wear or damage before reassembly. The WS99218 is a front-position repair sleeve, so confirm the vehicle application and engine configuration against the fitment list before service.
