FAQ:
What kind of hammer should I use with the seal driver?
For best results use a rubber or plastic hammer such as a dead-blow hammer. Do not use a metal hammer as the tool could be damaged.
How do I set the seal depth while using the seal driver?
The Merchant Automotive seal drivers are precision machined with positive stops to properly index and set the depth on your seals when properly used.
Can I replace the front output shaft seal with the transfer case installed in the vehicle?
Yes, after removing the front driveshaft the seal can be removed and replaced without removing the transfer case from the vehicle. Some people feel that it can be easier to remove the transfer case and replace the seals on a workbench though.
