A small internal leak in the rear main seal isn’t just a minor inconvenience; it’s a shocking issue that could lead to thousands of dollars in unnecessary repairs down the line. ### Why the Rear Main Seal Matters The rear main seal connects the driveshaft to the transmission and maintains a watertight, airtight seal within the rear axle housing.
