I recently purchased a 95 jeep grand cherokee. I ordered new control arms for it because they were only 30 each with new bushings already installed. I went to change them yesterday and i couldn't get the front cam bolts out. I got the lock nuts off and tried turning the bolts out and they would only turn a short distance then "spring" back to their original position. I had it jacked up with the suspension hanging freely and i tried putting jack stands under the front axle. Either way it made no difference. I even used a 4 foot breaker bar and it kept wanting to go back to where it was. I screwed the nut partially on the bolt and hit it with a hammer but no luck. Any ideas?
