Pivot Ring Removal
5. Use a screwdriver to remove the radial rings and thrust ring from the pivot ring. See Figure 7-36.
3. Remove the steel balls through the bearing filler plug hole. To work the steel balls forward, insert a putty knife between the pivot ring and the housing. See Figure 7-34. Use care to prevent damaging the radial rings. Move the pivot ring slightly from side to side while working the putty knife toward the bearing filler plug hole. NOTE: If the pivot ring does not spin or even turn, it is an indication of damaged radial rings and/or excessive wear to the channel in the housing. If this is the case, replace the entire drive unit. No further disassembly is necessary.
