  Q: How to replace the front crankshaft seal for the Honda Ridgeline?

  A: Remove the crankshaft position sensor, then remove the Timing Belt and crankshaft sprocket. Carefully pry the seal out of the engine with a screwdriver or seal removal tool. If you use a screwdriver, don't scratch the housing bore or damage the crankshaft. If the crankshaft is scratched, the new seal will end up leaking. Clean the oil seal bore and coat the outer edge of the new seal with a small amount of engine oil to ease installation. Apply multi-purpose grease to the seal lip. Using a seal driver or a socket with an outside diameter slightly smaller than the outside diameter of the seal, carefully drive the new seal into place with a hammer. Make sure it's installed squarely and driven in to the same depth as the original. Reinstall the crankshaft sprocket and timing belt. Run the engine and check for oil leaks at the front seal.

  Q: How to remove and replace a rear main seal without removing the oil pan or seal retainer for the Honda Ridgeline?

  A: Remove the driveplate. The seal can be replaced without removing the Oil Pan or removing the seal retainer. However, the lip of the seal is quite stiff and it's possible to cock the seal in the retainer bore or damage it during installation. Pry out the old seal with a screwdriver. Carefully pry the rear main seal out - don't damage the surface of the crankshaft or the new seal will leak. Apply multi-purpose grease to the crankshaft seal journal and the lip of the new seal, then carefully drive the new seal into place with a seal driver. The lip is stiff, so carefully work it onto the seal journal of the crankshaft. Don't rush it or you may damage the seal. Drive the seal in squarely and only until it is flush with the back of the seal plate, no further. Make sure the spring side is facing in.
