So the driveshaft/tailshaft whatever you want to call it in your area. It's out.
Some video on the seal that looks fine to me. Maybe you can tell me something different. The front universal joint is not rotating properly so I am going to look at it before cleaning the whole shaft and repainting it. This shaft was made as a one piece shaft to replace the 2 piece shaft because the 2 piece shaft has a problem with the centre bearing either blowing apart or causing vibrations under acceleration so I had this shaft made about 10 years ago.
More to come
