Question about TCI 2.5\" Lift I put my lift on back in March and had a slight vibe that got beter when I droped the tranfer case. But it has gotten worse now. Its a 2.5" all spring with a zero rate in back. Now I'm begining to wonder If I put the springs on backwards. The u-bolts lean forward at the top which to me says the push the pinion down in front. Everythig is snug and tight. Does the longer side of the spring goto the front or the back?? About the truck its an 89 with a SYE and a CV shaft. I also droped the x-fer case which helped but the vibes coming back now.
