After you put on the New Shackles, you measure from "Level Ground" to top of wheel well...so you have to do the same for the front...you turn your Torsion bars untill you get the same Measurement...I turned mine 10 to 15 times till I got the right measurement...the thing to do is you turn one side around 8 times and then you have to Flex the side that you turned, which means you drive your X on top of a curb or something and then back to level ground untill it settles to the new turned torsion, and then measure from level ground to top of wheel...Turn Torsion more or less (depends on result of the measurement)...and then you do the same to the other torsion Bar...and then when all is well and done...go have a cold Brewskie...
