FIGURE 1 - AXLE SEAL PROTECTOR
A new low cost disposable Axle Seal Protector (Figure 1) is now available for 1989 and prior models equipped with the above transmissions. The
advantage of this Axle Seal Protector is to prevent axle seal damage during installation of the right side Drive Axle. The right side (both sides for some
manual transaxles) Drive Axle has male splines and a snap ring groove that can potentially nick or cut the seal when the Axle Seal Protector is not used.
