Hello everyone - I hope someone can help.
Last year I replaced the pinion seal on my 1968 Road Runner 8 3/4 "742" case. After receiving a new seal and then comparing it to an NOS seal, I went with NOS since it was obviously more beefy and the newer one appeared cheap and thin (both the rubber and the metal).
Here I am a year or so later, and the seal is leaking again. Not sure if it was faulty or whether I didn't tork the pinion nut tight enough.
I used a tork wrench and it did not leak until now....
Anyone have any good tips? I plan on installing another NOS seal this weekend. Oh, I do not have a lift. I jacked up the car and used jack stands - which also makes tightening/loosening with a breaker bar a biotch - not much leverage.
