The max or typical max Z angle is 35*...you should look to keep
that angle as small as possible
Both U-Joints should have the same Z angle and it is the rear that changes
during travel. Can not remember the tolerance, but it is tight (small)
DO NOT bite on the wedges that some lift companies have for the rear...that
corrects visually, but now the two U-Joints are no longer of the same Z angle
If a new drive shaft is being installed...make sure they are correctly
phased and square to the symmetrical center line of the shaft. The
jig they use to hold while welding must be kept in good working
order (alignment)
With increased Z Angles, the slip joint (spline) MUST be kept GREASED WELL
If your vehicle has a carrier bearing...lifting that will have
the short, splined drive shaft approaching that 35* max Z Angle
