What does a rear crankshaft seal do?

The rear crankshaft seal is located at the back of the engine, where the crankshaft exits the engine block to connect to the transmission. Its main job is to prevent engine oil from leaking out of the crankcase.

Why does this seal come in two pieces?

A two-piece seal design can often be easier to install than a one-piece seal, especially in tight engine bays. It allows the seal to be fitted around the crankshaft without needing to remove the crankshaft itself.

What is covered by the limited 5-year warranty?

The limited 5-year warranty covers defects in materials and workmanship. It's recommended to check the manufacturer's warranty documentation for full details and any exclusions.

About this part

Product Details

If you're dealing with oil leaks from the back of your engine, it's likely time to replace the rear crankshaft seal. This part is crucial for keeping the engine oil contained within the crankcase, preventing it from leaking onto your transmission or the ground. This Omix seal is designed to fit a wide range of Jeep SJ models from the early 70s through the early 90s, including popular vehicles like the CJ5, CJ7, Cherokee, and Grand Wagoneer, when equipped with a V8 engine.

This seal comes as a two-piece design, which can make installation a bit more straightforward compared to a one-piece seal, especially when you're working in tight spaces. Omix builds these to meet or exceed the factory specifications, so you can be confident it will perform as expected. It's a direct fit replacement, meaning it's made to install without needing any modifications to your engine block or crankshaft.

When you're replacing a crankshaft seal, it's a good idea to inspect the crankshaft itself for any scoring or damage that could cause a new seal to leak prematurely. This Omix seal is backed by a limited 5-year warranty, giving you peace of mind with your repair.
