5 7 drop 2007 new body style crew cab has vibration at 55mph and 75 mph. front pinion from what I can see is -5 degrees and the rear is +5 degrees. what should it be. thankx in Advance
if i recall correctly, should be a variance of 6 degrees or less from the tranny to the rearend, appears u have 10.....did u check the carrier bearing on the driveshaft?
daveg is right. The rearend pinion sould be equal to the trans pinion then point the rearend down 2 to 5 deg. 6 is pushing it, but can still be tollerable.
