Timken 710237 Engine Crankshaft Seal - Rear

Timken Rear Engine Crankshaft Seal

Timken 710237 is a rear engine crankshaft seal built to help control oil leakage and keep contaminants out of the engine sealing area. It is a direct-fit service part for a wide range of GM, Saab, Saturn, Isuzu, and Pontiac applications, including rear seal replacement on Buick LaCrosse, Chevrolet Malibu, and Cadillac CTS models.

Key Features

• Precision sealing design helps retain lubricant at the crankshaft
• Reinforced outer case helps reduce installation damage and improve durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and promote seating
• Internal contamination exclusion system helps block debris that can lead to leakage
• Vent holes allow lubricant flow around the seal lip to help reduce heat build-up

Detailed Description

Timken 710237 is engineered for rear crankshaft sealing in engines where oil control is critical. The seal’s construction combines a reinforced outer case with a ribbed inner diameter to support a secure fit on the shaft surface, while the contamination exclusion system helps keep dirt and debris away from the sealing lip. This makes it a practical choice for rear crankshaft seal service on vehicles such as the 2010-2016 Buick LaCrosse, 2014-2016 Cadillac CTS, and 2013-2015 Chevrolet Malibu. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Rear main oil seepage or leakage at the crankshaft
• Contamination entering the seal area during operation
• Seal wear caused by heat build-up around the lip
• Poor sealing from minor shaft surface imperfections
• Repeat leaks after prior crankshaft seal service

Installation Notes and Tips

Inspect the crankshaft sealing surface before installation and clean the surrounding area thoroughly. Use proper installation tools to avoid damaging the seal case or lip, and verify correct seating depth during assembly. For fitment verification, this part fits 2016-2017 Buick Envision, rear; 2010-2016 Buick LaCrosse, rear; and 2014-2016 Cadillac CTS, rear.
