How to remove and install the crankshaft seal on Hyundai Sonata?

Lift the transaxle out of the car and then the driveplate or flywheel has to be pulled out. Whether it is a slotted or a solid Crankshaft Seal, pry it out from the rear of the engine using a seal removal tool or a flat-end screwdriver, risking the crankshaft or the seal bore. Afterwards, clean the seal bore area within the block with a shop towel to ensure that the area is free of any oil or dirt deposits. Apply oil on the OD of the seal and place it over the extremity of the crankshaft with the lip facing the engine. Ideally, a seal installation tool can be used to push the new seal back into its proper position while it is noted that a small oil drain in the separator must be in the lowest position. If the proper tool is not available, the big socket must be used to insert the new seal gently into the seal bore in a way they are perpendicular to the surface of the engine block and lies flush with the outer perimeter of the block. Lastly, bolt on the driveplate/flywheel, and then the transaxle.
