This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Oil leakage at the crankshaft seal area
• Seepage from a worn or hardened engine seal
• Loss of sealing performance during engine service
• Replacement needs after crankshaft or timing-area repair
• Fitment-matched sealing service for Honda Civic and Toyota Corolla applications

Installation Notes and Tips

Confirm the inside diameter, outside diameter, and thickness against the removed seal before installation. Clean the sealing bore and shaft surface thoroughly, and inspect for wear, scoring, or contamination that could affect sealing performance. Use proper installation tools to keep the PTFE sealing lip square during placement, and verify the seal orientation matches the engine design before reassembly.

Quality Assurance

Elring is a recognized name in engine sealing systems, and this crankshaft seal is specified with clear dimensional and material data to support accurate parts selection. Verify application details against the vehicle service information and the removed component before ordering.
