• Service issues on rear-position Cadillac CTS and Cadillac STS applications

Installation Notes and Tips

Verify the bore diameter, outside diameter, width, and vehicle application before installation. Clean the sealing surface thoroughly and inspect the shaft or housing for scoring, corrosion, or wear that could affect seal performance. Confirm rear-position fitment for 2004-2012 Cadillac CTS and 2006-2011 Cadillac STS before replacing the existing seal. Use proper installation tools to avoid damaging the sealing lip or spring.
