Lowering Problems
I'm having trouble lowering my car. I jacked it up, have the wheel off and lifted up on the A arm so it would take pressure off. but the bolt still will not budge. I broke a wrench trying to turn it. Any Ideas? Do i need to have both wheels off and taking the pressure off both sides by lifting up both A arms? Pictures would be great but just any advice would help.

Lifting up on the frame member only increases the pressure on the bolt head.
The wheel should be hanging down down, then
you need to lift up on the leaf spring to relieve the pressure on the head of the bolt. Many people doing this have been able to turn the bolt by hand after relieving the pressure.
Take a look at the first picture in Post#2 in this thread (it's of the rear suspension):

You can see the bolt going through the leaf spring. The bolt actually screws in from below the leaf spring. The rubber bushing on the head of the bolt is underneath the leaf spring and rests on that arm frame member (in the picture you can't quite make out the frame member, but the rubber bushing is resting on it).
All you're doing when you raise up that arm is that you are squeezing the rubber bushing even tighter between the frame member and the leaf spring.
Lift up the leaf spring with a jack and you'll see daylight between the rubber bushing and the frame member and may even be able to turn the bolt with your fingers.

If you remove the lower shock bolts and just use a pry bar between the spring and the lower control arm you will have no trouble with the adjusting bolts.
