Fig. 4 Drive Flange With Polygon Bearing Assembly

Differential, Removing and Installing

Notes:

- Polygon bearings can only be replaced together with drive flange.
- Look for visible damage to polygon bearings.
- The rough operation of the polygon bearing with the drive flange not installed is not an indication that the bearings are malfunctioning. An acoustic check can only be carried out while installed.
- A spacer ring is installed between the polygon bearing and differential pinion for drive flanges with a spline diameter of 30 mm.

5. Spacer Ring (is Installed Additionally If Spline Diameter Is 30 mm)

Note:

- Needle bearings (polygon bearings) do not turn easily with drive flange removed. This does not indicate a bearing is malfunctioning.
