my pinion angle before SYE install is 20 and 10 degrees...bad for the vibration... my install should start this week hopefully...is this a normal or close to normal degree change when lifting 3.5 inches?
i have them ready to be put on with my sye kit...this is stock shown on everyhting besides the lift
this is by far the most reassuring response i've had in a while unk: maaahaloYou should be good to go then. Just put an angle finder on the drive shaft and a perpandicular or parallel part on the center section. I put a bottle jack under the pinion snout of the diff and crank 'er up until the readings are within 3 degrees, then adjust the uppers for length and install.
There should be a couple of flats on the rear of the centersection of the axle housing, to either side of the diff cover (where the axle tubes fit in). Those are 90 degrees to the pinion angle.
