3.909	Reused bearing	1.45 to 2.50 Nm 15 to 25 kgfcm, 12 to 22 in.*lbf)
4.300	New bearing	1.41 to 2.66 Nm (15 to 27 kgfcm, 13 to 23 in.*lbf)
4.300	Reused bearing	1.42 to 2.45 Nm (15 to 24 kgfcm, 13 to 21 in.*lbf)

Standard Total Preload (for BD22A,BD22AN):

Reduction Ratio	Bearing	Preload
3.909	New bearing	1.87 to 4.15 Nm 20 to 42 kgfcm, 17 to 36 in.*lbf)
3.909	Reused bearing	1.90 to 3.97 Nm 20 to 40 kgfcm, 17 to 35 in.*lbf)
4.300	New bearing	1.85 to 4.10 Nm (19 to 42 kgfcm, 17 to 36 in.*lbf)
4.300	Reused bearing	1.88 to 3.92 Nm (20 to 39 kgfcm, 17 to 34 in.*lbf)

If necessary, disassemble and inspect the differential assembly.
