The diagonally shaded area in the figure shows stamping point
for replacement frequency of front oil seal.

The following table shows if collapsible spacer replacement is
needed before replacing front oil seal.
When collapsible spacer replacement is required, disassemble
final drive assembly to replace collapsible spacer and front oil
seal. Refer to RFD-18, "
Disassembly and Assembly" .
CAUTION:
Be sure to make a stamping after replacing front oil seal.

After replacing front oil seal, make a stamping on the stamping point in accordance with the table below in
order to identify replacement frequency.
CAUTION:
Stamping shall be made from left to right.
