Had a few drops of fluid on garage floor under the rear axle gear box location--Auto has only 18380 miles on it--Dealer service dept said it needs new pinion seal and wheel speed sensor leaking---Est. cost $309 + tax--The fluid drops were about 6 weeks ago and haven't shown up again--My own opinion is service dept. is drumming up business.
I had always wanted to own a Roadmaster since I was a kid of 11 years old--that was in 1938--I have the Roadmaster Limited Collectors Edition 1996--It truly is a wonderful auto--I must have been a smart kid back then in 1938 to recognize good value--
The pinion seal leaking is a common problem with the differential in question. The repair cost seemed reasonable, and should have been done. When I first brought mine home (bought it used a month ago, drove it home from Texas to VA) I too noticed the differential leaking. Took it and had it fixed, read on other sites the seal used is only one sided. There are newer two sided seals available that will permenantly fix this problem.
It might behoove you to check the fluid level in the differential, since it has stopped dripping on the floor. Might be low, might be empty. If you are low, and you have a posi rear, you might damage that.
