I'm not nervous in the least. I've done this sort of work before on other vehicles. The part I'm concerned about is having a decent manual for this and future maintenance. The info provided by Aveo5_boy is very helpful and much appreciated. I've never been able to find a Haynes manual. I don't believe one exists. The chevy/daewoo factory service manual costs about as much as the car. As far as tools go, I've always used the standard torque wrench. I've never had to use a Angular Torque Gage before.
