How to replace the crankshaft seal and ensure proper installation on 2012 Nissan Sentra?

Loosen the right front wheel lug nuts, then raise the vehicle and support it securely on jackstands before removing the right front wheel. Next, take out the right inner wheel well and the drivebelts. Remove the crankshaft pulley bolt, and if needed, have an assistant hold the crankshaft from turning by wedging a screwdriver in the flywheel/driveplate teeth through the access hole. Use a puller to remove the pulley from the crankshaft, ensuring the proper adapter is used to prevent damage to the threads or end of the crankshaft, and that the jaws of the puller are secured to the hub of the pulley. Utilize a seal-puller tool or a screwdriver with a taped tip to carefully pry out the seal without damaging the seal bore or scratching the crankshaft snout. Clean the bore in the timing chain cover and coat the outer edge of the new seal with engine oil or multi-purpose grease, also lubricating the seal lips. Using a seal driver or a socket slightly smaller than the seal's outside diameter, carefully drive the new seal into place, ensuring it is installed squarely and to the same depth as the original, while checking that the garter spring remains in place. Remember that the oil seal lip faces the engine and the dust seal lip faces the pulley. Reinstall the crankshaft pulley and drivebelt, tightening the crankshaft pulley bolt to the specified torque, then run the engine and check for oil leaks.
