Hello everyone reading this, hopefully someone can help. You always have in the past. Because of everyones help and posts on this site I have saved thousands of dollars fixing those minor little things that go wrong, axcel seals, starter, power window, fuel filter, brakes, hot feet, weird rattle from the dash, gas gauge, the part that distributes fuel to all the cylinders. I think I named them all. But with the long weekend I am going to attempt to replace the upper and lower ball joints and put on new shocks while I am at it. I have never done it before and I only have the one car and friends are far away so if I screw something up or need a special tool I takes a while to over come those problems, so I want to make sure I have everything I need before I start the job. So my question to all who reads this is "Please tell me what I need to do to replace the ball joints and what tools I need to make the job go smoothly?
Your help is always appreciated.
