Description
Part 4778228 is a rear crankshaft sealing kit for selected Chrysler-family engines, intended to address oil loss at the back of the crankshaft. It is a repair kit rather than a loose generic rubber seal.
The listing applies to specific older 5.2L and related 3.9L engine families, including early Grand Cherokee ZJ and Dodge pickups. Do not use a vehicle-only search for fitment: engine family and year determine the correct rear-main arrangement.
