www.perinatology.com Review:

I bought it for my bushings in the front suspension of my explorer since they don't have grease fittings anymore. I used it one time and no more squeaks when i have to go through a dip in the road. I love to hear nothing anymore, the constant squeaks evrytime i hit a bump was driving me crazy, not any more.

The book is very thorough on the topic. I recommend actually following along with your excel program while reading the book because you will learn the material more effectively. At times, there were some parts where I was lost on how to actually do things but eventually I figured it out.
