Common signs of worn connecting rod or main bearings include a deep knocking or rumbling noise from the engine (especially under load or at idle), low oil pressure, metal shavings in the oil, and in severe cases, engine seizure. These symptoms should be diagnosed and addressed promptly, as continued operation on worn bearings can cause catastrophic engine damage.

Bearing size designations refer to the bearing's inside diameter relative to a standard crankshaft or camshaft journal. "Standard" size fits an unworn, factory-spec journal. Undersize bearings (like 0.001", 0.010", 0.020") are used when the journal has been machined down slightly during an engine rebuild to correct wear or damage. Always match the bearing size to your machinist's measured journal diameter, not just the original factory spec.

Clevite's aluminum silicon bearing material is engineered with roughly 60% more silicon than typical competitive replacements. This provides better conditioning of the journal surface during break-in and operation, which translates to greater resistance to seizure and wear over the life of the bearing — particularly valuable in high-load or high-performance applications.

Yes — checking oil clearance with Plastigauge or a micrometer is a standard, essential step of any bearing installation. It's the best way to confirm the bearing and journal combination is within spec before final assembly. Clevite publishes minimum and maximum vertical oil clearance specifications for each bearing to help verify a proper fit.

Clevite engineers its bearings to meet or exceed OE specifications for dimensions and clearances. Confirm the exact bearing series, size (standard or undersize), and material grade for 2233729 matches your engine's specific application before ordering, since bearing materials and dimensions can vary by year, make, and model even within the same engine family.

Engine bearing replacement is a major internal engine job that requires disassembly, precise clearance measurement, and careful reassembly to factory torque specs. While experienced DIY engine builders do this work themselves, it's an advanced repair — most owners rely on a qualified engine builder or machine shop, especially if the crankshaft or camshaft journals need machining.

Yes. All Clevite engine bearings sold at AutoNation Parts are 100% brand new and backed by a manufacturer warranty of at least 12 months.

You can verify exact fitment by using our vehicle selector tool at the top of the page to input your year, make, model, and trim level.
