DIY Front Alignment Troubles
I cant quite make out your camber gauge in one of your pictures. But I think you have the same Longacre unit I have, I had doubts and concerns last year aligning my Duster myself with it and it turns out the instructions included with the gauge were misleading. i could read accurate camber measurements, but caster measurements were not. It all had to do with what buttons to push when. I tried to contact Longacre themselves but only was able to talk to someone who confirmed the gauge he was using worked correctly. It was only till I found this youtube video did I get clarification on what button to push when. Hope this helps
