This rear crankshaft seal is designed to prevent engine oil from leaking out of the crankcase at the rear main bearing, ensuring proper lubrication and preventing oil loss. Manufactured with high-quality sealing materials, it provides a reliable barrier against oil passage, unlike a hardened or cracked seal. Operators may notice oil spots under the vehicle, a persistent smell of burning oil, or a gradual decrease in the engine oil level.

Torque all suspension fasteners to specification — under-torque causes wear, over-torque causes fatigue cracking. Replace bushings in pairs. Grease all zerks after fitting. Check alignment after suspension work.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a failing rear crankshaft seal is typically an oil leak visible on the underside of the engine, often near the transmission. If left unaddressed, the leak will worsen, potentially leading to low oil pressure and increased oil consumption. The ultimate risk is severe engine damage due to insufficient lubrication.
Ensure the crankshaft sealing surface is perfectly clean and free of any nicks or burrs before attempting installation. Use a proper seal driver tool to install the seal straight and avoid damaging its lip.
Inspect the rear main bearing and the crankshaft sealing surface for wear or damage when replacing the rear crankshaft seal.
