My mechanic said- "the transfer case needs to be taken apart to replace the front seal." {Is this true?}

Transfer cases do have oil seals in them. Not sure which trans case you have but parts are not that expensive.

There is a 4405 rebuild diary thread posted on this site that implies that the front input shaft must be removed in order to replace the seal. That would, of course, require the t-case to be removed and opened up. I'm sure this is typical of other Borg Warners. And, if you're going that far, you may as well have the insides inspected and parts replaced; especially, the shift fork which is a common wear item.

I am going to try and put this entire thread together much as I did the 4R70W Diary, so those just needing basic info do not have to sift through a lot of chatter throughout the thread. I will create and link another comment thread for those comments - which is here...

Not sure which seal you are talking about, but as was said earlier for the 4405 case you have to take it apart. If you have the AWD you might have the 4404 and it's rebuild is at this link How To: Rebuilding a Borg Warner 4404
