1 Suburban
kept 10 bolt front and rear ends until 1991. Keep in mind spline
change in 1990.
2 If vehicle
was manufactured in 1989 or 1990 check spline count to determine which
model is needed.
3 Some 1988
and newer trucks use a unique Dana 70-3HD. Special fitment is
required.
4 1999 and
newer axle shafts may need .005" dia. removed for proper fit.
5 4.56 &
higher ratios must use thick gearset.
