I would have to have a shop do it. I deliberately keep myself ignorant of how cars work as much as possible. It's hard work as I really do have a good memory and tend to have a difficult time forgetting something once learned.
The thing is, I hate working on cars. I never fail to cut myself while working on them, even if I'm just changing the battery. And they're dirty and I have to lay down on pavement or concrete and slide around and turn end up punching solid pieces of metal when my wrench slips off a stubborn nut which is extraordinarily painful.
But I'm full aware that for the most parts a person gets raped every time he/she engages the services of an auto mechanic. I know that I could never justify having a mechanic do the work if I knew that I could do it myself (much the same conclusion Paige seems to have come to here). It's just so damned expensive.
If you know cars, Fredster, now is your chance. You've finally found my weakness and I suggest capitalizing on it. Cars, and the way they work, are things I cannot speak intelligently about. I refuse to learn. My advice to Paige is to pay the extortion and have it done. It's worth every penny.
