Well, it was the first time the car has been driven in 4 years. The car has been in the shop almost 4 years and at some point, some jackass drained the rear diff fluid and replaced the drain plug without re-filling the fluid. I assumed that since there was no rear-end work done what-so-ever that there would have been no reason for someone to drain the fluid. That's what I get for assuming. Now, I am going to have to replace the ring and pinion and all the bearings in the Ford 9" 3rd member. Is there a good set I should be looking for? Is the Summit racing street/strip ring and pinion OK?? And finally, how hard is it to replace these burned out parts in the 3rd member. Is this something that I can reverse engineer or should I just turn it over to a professional? I would like to do it myself and I have considerable shop knowledge and skill but this is something I have never attempted.
