DESCRIPTION

To provide easier removal of the A/T differential bearing retainer, two threaded bolt holes have been added (Figure 1).

Figure 2.:

The retainer is removed by inserting a M8 x 30 bolt into each hole, turning them alternately and evenly until the retainer is unseated (Figure 2).

When performing this procedure, the following precautions must be observed:

Figure 3. M8x30 Bolts:

- To prevent retainer thread damage, use bolts that are threaded from head to tip (Figure 3).

- Make sure the bolts have squared, smooth tips (Figure 3).

- Do not use power tools. Use hand tools only.

- To prevent damage to transaxle case, tighten both bolts alternately and evenly.
