EL falcon. just changed diff, got problem - 6/23/2008 1:05:52 AM    sglen82   Posts: 2 Score: 0 Joined: 6/23/2008 Status: offline Hey, Just pulled out my old diff which was buggerd, and slapped in one i bought. The problem is that its shakes like shit, from about 0-50km it shakes and is good when it gets past there. When i put my foot down hard on take off, she goes sweet as drives like a charm, take my foot off and shaking. One thing that has changed is the gear ratio from 3.08:1 to 3.23:1 Could really use some advice. Cheers evryone Scott Post #: 1
