Happend to my 89 Indy. The previuos owner drove it more broke the bearing in it. Spun the driveshaft gear around in the chain case and ate it all up. Broke speedo bearing,speedo key, and chewed up the end of the driveshaft and it resulted in me getting another drive shaft. Ended up being around 300-400$ to fix it up.

Replace the seal. Lot cheaper in the long run and should not take more than a couple hours if you are inexperienced. Good luck!
