2.5\" Rancho lift (wedge and vibration) Hey guys, Just installed 2.5" lift on my 86 blazer. Came with 2.5" front springs and 2.5" rear block (shaved 2.5 deg.) and 6 shocks. Took about 2 days and 10 hours to install. Here are the questions: 1) Once I installed the front springs, stupid me did not see the 2.5degree wedge that is supposed to sit under the front sping pack for "improved driveline" performance. Now... my stearing wheel sits about 30 degress too much (clockwise). Could this be the reason? Anyone have a similar experience? Do I need to install this wedge? 2) I now have low speed vibration (5mph and 15-25mph). Gets worse when under-load. Is it time for U-joint replacement? How do I know if my driveline angle is acceptable? Did I do something else wrong! Appreciate any help you can give. By the way, rides great. No pull or sway and stops strait. Much softer ride than stock front spings/shocks. Would highly recommend the kit.
