Inspect Differential/Axle Shafts Assembly:
1. Visually check overall condition of assembly.
2. Use a feeler gauge to measure “go/no go” air gap
(B) between side surface of shim washer (A) and
side surface of lower case (C):
• “GO” air gap should be 0.18—0.36 mm (0.007—
0.014 in.),
• “NO GO” air gap is anything greater.
3. If measurement results in a “NO GO” reading, worn
or damaged components must be replaced.
Disassemble Differential/Axle Shafts Assembly:
1. Put inward pressure on both axles (D and E) as you
lift differential assembly (F) from lower case.
2. Carefully remove axle shaft assembly components
from ring gear (G). Be sure to remember each
components orientation to its neighbor and to the
ring gear (G). You may want to mark the same
side of each component to help keep the
orientation straight.
3. Clean components individually once disassembled,
be sure to remove all sealant material from upper
and lower case halves.
4. Inspect each component (especially both upper and
lower case halves) closely for wear, scoring,
cracks, chips, or discoloration (burnt). Replace
components as necessary.
5. Replace seals (I and F) every time transaxle
housing has been separated.
