Wperk, how did things work out for you? I too am hesitant about pulling my plug for fear of not getting it back in.
I am going to take a crack at the pinion seal(where it is leaking) this weekend, but will need to fill with more oil at some point.
This video is no longer available, I have a 96 ltd with significant rust on the rear differential as well, and was overall planning on doing a similar coating of the entire thing. Could you please let me know what this video used/did?
