If you have replaced the rear seal on your 2002 Cadillac Escalade's transfer case and it is still leaking, there could be a few possible reasons for this issue. Here are a few potential causes and steps you can take:
Improper installation: Double-check the installation of the new seal to ensure it was installed correctly. Make sure it is seated properly and tightened to the correct torque specifications.
Damaged or worn transfer case components: If the transfer case has internal damage or worn components, it can cause the seal to leak even after replacement. In this case, it may be necessary to inspect and repair or replace any damaged parts within the transfer case.
Excessive pressure or fluid level: The seal could be leaking due to excessive pressure within the transfer case or an overfilled fluid level. Make sure the fluid level is correct according to the manufacturer's specifications and that there are no blockages or restrictions in the ventilation system that could cause pressure buildup.
Regarding the small hole in the seal, it is essential to determine its purpose and orientation. Without specific knowledge of the design of your particular seal, it is challenging to provide a definitive answer. However, if the hole is part of the design and not a result of damage, it is likely there to allow for the equalization of pressure on both sides of the seal. It would be best to consult the manufacturer's documentation or reach out to a Cadillac dealership or a qualified mechanic for clarification on the proper orientation of the seal.
