Final Drive
DISASSEMBLY1. Remove final gear.
2. Remove speedometer drive gear by cutting it.
3. Press out differential side bearings.
^ Be careful not to mix up the right and left bearings- RS5F32A.
4. Remove viscous coupling-RS5F32V.
5. Drive out retaining pin and draw out pinion mate shaft.
6. Remove pinion mate gears and side gears.
INSPECTION
Gear, Washer, Shaft and Case
^ Check mating surfaces of differential case, side gears and pinion mate gears-RS5F32A and 32V.
^ Check viscous coupling-RS5F32V.
^ Check washers for wear.
Viscous Coupling-RS5F32V
^ Check case for cracks.
^ Check silicone oil for leakage.
Bearing
^ Make sure bearings roll freely and are free from noise, cracks, pitting or wear.
^ When replacing tapered roller bearing, replace outer and inner race as a set.
ASSEMBLY
-RS5F32A & RS5F32V-
1. Attach side gear thrust washers to side gears, then install pinion mate washers and pinion mate gears in place.
2. Insert pinion mate shaft.
^ When inserting, be careful not to damage pinion mate thrust washers.
-RS5F32A & RS5F32V (Differential case side)
3. Measure clearance between side gear and differential case with washers using the following procedure:
a. Set Tool and dial indicator on side gear.
b. Move side gear up and down to measure dial indicator deflection. Always measure indicator deflection on both side gears.
Clearance between side gear and differential case with washers: 0.1 - 0.2 mm (0.004 - 0.008 inch)
c. If not within specification, adjust clearance by changing thickness of side gear thrust washers.
Side gear thrust washers: Refer to Application and ID.
-RS5F32V (Viscous coupling side)-
4. Measure clearance between side gear and viscous coupling with washers following the procedure belongs.
a. Set remaining side gear with washer on pinion mate gears.
b. Measure distance "X".
^ Measure in at least 4 places around the edge of the side gear and take an average. At least 4 measurements are needed because the side gear may be uneven.
c. Measure dimension "Y". Clearance between side gear and viscous coupling with washers can be obtained by "X + Y - 2A".
Specification: 0.1 - 0.2 mm (0.004 - 0.008 inch)
d. If not within specification, adjust clearance by changing thickness of side gear thrust washer.
Side gear thrust washers for viscous coupling side: Refer to Application and ID.
-RS5F32A & RS5F32V-
5. Install retaining pin.
^ Make sure that retaining pin is flush with case.
6. Install viscous coupling-RS5F32V.
7. Install final gear.
^ Apply locking sealant to final gear fixing bolts before installing them.
8. Install speedometer drive gear.
9. Press on differential side bearings.
