The transfer case output shaft seal is seeping at 115,000 miles. I noticed a burnt smell in the garage and see a film around the seal (seeping onto the exhaust pipe).

Anyone have any dealership or DIY experiences replacing just the output shaft seal? I saw some forum threads about entire PTU replacements. This article provides the basics for a seal-only replacement:

Thanks in advance.
