Getting ready to (finally) replace the front seal. In the seal kit is the seal, a plastic seal pilot, an alignment tool, and a thin black seal ring of some sort. The only reference I have available (sadly) is a Dodge service manual which is, at best, vague and makes no mention of this thin ring. Where does it go and which way does it face? The manual also instructs the installer to apply Loctite 277 to the OD of the seal. My parts guy struck out on this. Is there an acceptable substitute? I'm sure this will all make more sense once I get it apart, but I want to be sure of what I'm going to find in there and double sure I have everything necessary on hand. Any advice/input/tips are appreciated. Thanks.
