What This Seal Helps Address

• Transmission fluid leakage at the rear seal area
• Contamination entry from dirt, dust, and moisture
• Grease loss at the sealing interface
• Wear-related sealing issues on older manual transmission applications
• Replacement needs during transmission service or rebuild work

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation. Confirm the vehicle application and transmission position against the fitment list, especially on Chevrolet K30, P30, C20, and GMC Jimmy rear manual transmission applications noted with Muncie transmission references. Clean the sealing bore and shaft surface thoroughly before installing the new seal to help achieve proper seating and sealing contact.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The seal construction is intended to protect wheel-end and transmission components from contamination while helping preserve lubricant over the service life of the bearing or seal assembly.
