I have a 1998 Pathfinder and took it to a mechanic for rear engine seal replacement. Their estimate was $1,200 to replace. They had it for two weeks and I called today and they said that they replaced the rear main seal and had to sand off a burr on the shaft. After repair, they said that the rear seal still leaks and that they thought that it was due to crankshaft bearing wear and that it was basically not fixable, so the vehicle is basically ready for the junkyard. So I have two questions: 1. Does this sound reasonable? 2. What do I owe the shop for the work? Any advice would be appreciated.
