How do you replace the front crankshaft oil seal in Four cylinder engine on Lexus RX350?

Remove the crankshaft pulley and note how the seal is installed, ensuring the new one is positioned to the same depth and orientation. Carefully pry the oil seal out of the cover using a seal puller or a large screwdriver, taking care not to damage the crankshaft or distort the cover. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal, then install it in the cover with the lip facing inward. Drive the seal into place using a seal driver or a large socket and hammer, ensuring it enters the bore squarely and stops at the proper depth. Check the surface on the pulley hub for any grooves caused by long-term contact with the seal; if present, replace the pulley. Lubricate the pulley hub with clean engine oil and reinstall the crankshaft pulley, then install and tighten the retaining bolt. The remainder of the installation follows the reverse order of removal.

Lexus RX350 Crankshaft Seal

The Lexus RX350 Crankshaft Seal is responsible for keeping engine oil sealed within the crankcase to prevent vital components from losing oil and wearing away. Sitting right at the front end of the crankshaft, the Crankshaft Seal is a snug round barrier consisting of a metal shell bonded to durable rubber. By sealing escape paths for lubricating fluid, this Crankshaft Seal ring helps the Lexus engine maintain proper lubrication pressure and helps reduce friction between moving parts. When the Crankshaft Seal gets older, the RX350 can be identified by telltale oil drips on the driveway or an unexpected drop in the dipstick level, which are sure signs that it's a wise move to replace it before greater damage can occur. Over the years, the Lexus RX350 has been running on essentially the same metal-rubber composite type, so there are no wild generations to compare, only slight improvements in the quality of the materials applied, as they are better resistant to heat. The component is inexpensive and very important, so many owners of the Lexus RX350 prefer to keep a close check on mileage and replace the Crankshaft Seal when they notice wear indicators instead of having to undergo expensive internal repairs.

Should you need to purchase new auto parts for your vehicle, we strongly suggest you consider the genuine Lexus RX350 Crankshaft Seal available on LexusPartsNow.com. Our OEM Lexus RX350 Crankshaft Seal come with the reassurance of the manufacturer's warranty, a hassle-free return policy, and speedy delivery service, all at affordable prices online.
