Q: How do you remove and install the transaxle and crankshaft seal on Nissan Sentra?
A: Remove the transaxle and the Flywheel/driveplate. Use a screwdriver wrapped with tape to pry out the Crankshaft Seal, being careful not to gouge or nick the housing. Lubricate the crankshaft seal journal and the lip of the new Crankshaft Seal with multi-purpose grease. Install the Crankshaft Seal with the seal lip toward the engine and the dust seal toward the transaxle. Tap the Crankshaft Seal into place using a seal driver to ensure it doesn't become tilted. Install the Crankshaft Seal so that its rear edge is flush with the face of the engine block, or up to 0.019 inch recessed. The remainder of installation is the reverse of removal. Reconnect the battery and perform the necessary re-learn procedures.
