This is why I should stick to computers and pay somebody else to do these maintenance items I try to do. I don't do them so much to save money, but to carry on the dirty finger nail, wrench bending tradition my father tried to pass on to me...

Here's my problem - i drained my rear diff to put in the synthetic gear oil I just bought. When I realized that the pump I bought would not fit the quart bottles I have (the lable says fits quarts/half gallons/gallons), I decided to test if I was going to be able to pour the stuff straight in. With the fill/check bolt out, I stuck the neck of the bottle in, with the cap on still. Now the cap is in the rear diff...

What's going to happen if it stays in there? Any ideas on getting it out? Do I need to open the whole thing up?

My latest brain storm is to pour in the oil and see if it floats up where I can see and retrieve it near the fill hole. But given my track record...
