Okay guys, here is the story. I have an 06 3500 4x4 and took it in for an alignment and the tech told me it needed upper ball joints. So I took it apart and I found that the lowers also had some wear. I decided to do all of them. My question is, can I put the adjustable on the top only and the fixed ones on the bottom? Would it cause my truck to act funny? The reason I want to put the adjustable on the top is so that my alignment could be as close as possible to zero. I did put a 2 1/2 level kit on it and dont know if this will help. What ideas do you guys have?
