Removal
1. Remove hub and knuckle assembly from vehicle. See HUB & KNUCKLE ASSEMBLY under REMOVAL & INSTALLATION. Using
Knuckle Puller (T87C-1104-A), or a press and bearing puller, remove drive hub/rotor assembly from steering knuckle/dust shield
assembly.
2. Remove bearing preload spacer from hub. Spacer is preselected to provide correct bearing preload. Ensure correct spacer is installed
during reassembly. Install hub/rotor assembly in a vise. Scribe alignment marks on hub and rotor for reassembly reference.
3. Remove rotor attaching bolts and rotor. Use Bearing Splitter (D84L-1123-A), Shaft Protector (D80L-625-2) and a press, or Bearing
Puller (D80L-927-A) and Puller Attachment (D84L-1123-A) to remove outer bearing from wheel hub. Remove and discard outer and
inner grease seals. Using Bearing Puller (T77F-1102-A) and Slide Hammer (T-50T-100-A), remove races from steering knuckle. See
Fig. 3
.

Inspection
Thoroughly clean all parts in solvent. Check bearings, hub, knuckle and rotor dust shield for excessive wear or damage. If new bearing is being
installed, check bearing preload. See BEARING PRELOAD.
Bearing Preload
1. To check and adjust preload, Spacer Selector Set (T87C-1104-B) must be used. Prior to assembling hub/rotor assembly into steering
knuckle, install spacer selector into steering knuckle and clamp tool in vise. Tighten center bolt, in increments, to 36, 72, 108 and
finally 145 ft. lbs. (49, 98, 147 and 196 N.m). Each time center bolt is tightened, seat the bearings by rotating steering knuckle by hand.
2. Remove steering knuckle from vise. Reinstall steering knuckle in vise, clamping it where shock absorber mounts. Using an INCH lb.
torque wrench, measure torque required to turn center bolt. Ensure torque reading is taken just as wrench starts to rotate.
3. Spacer thickness is correct if torque wrench indicates 2.21-10.44 INCH lbs. (.25-1.8 N.m). If measurement indicates less than 2.21
INCH lbs. (.25 N.m), a thinner spacer must be installed. If measurement indicates more than 15.93 INCH lbs. (1.8 N.m), a thicker spacer
must be installed.
4. Bearing spacers are available in 21 thicknesses, in .0016" (.040 mm) increments. Spacer No. 1 is thinnest and No. 21 is thickest. See
PRELOAD SPACER AVAILABILITY table. Changing spacer thickness one increment will change bearing preload 1.7-3.5 INCH lbs.
(.2-.4 N.m). Ensure correct spacer is installed and preload is within specification. Remove spacer selector set.
PRELOAD SPACER AVAILABILITY NOTE:Rem oval of press-fitted dust shield from steering knuckle is not part of norm al bearing service. Dust
shield should not be rem oved from steering knuckle unless it is being replaced.

See STALL SPEED SPECIFICATIONS .
Testing Procedures
1. With engine at normal operating temperature, tachometer installed and parking and service brakes applied, perform transaxle stall test in
"D", "2", "1" and "R" ranges at full throttle and note maximum RPM obtained. Correct stall speed should occur at specified RPM. See
the STALL SPEED SPECIFICATIONS
.
STALL SPEED SPECIFICATIONS
2. If stall speed is too high in all shift ranges, the following components may be faulty:
Worn Oil Pump.
Oil leakage from oil pump, valve body or transaxle case.
Sticking pressure regulator valve.
3. If stall speed is too high in "D", "2" and "1", the following component may be faulty:
Slipping rear clutch.
4. If stall speed is too high in "D", the following component may be faulty:
Slipping one-way clutch.
5. If stall speed is too high in "2", the following components may be faulty:
Slipping intermediate band.
6. If stall speed is too high in "R", the following components may be faulty:
Slipping Low/Reverse Clutch.
Slipping Front Clutch.
7. If stall speed is too low in all shift ranges, the following components may be faulty:
Slipping torque converter one-way clutch.
ROAD TEST
1. Before road test, ensure that fluid level, fluid condition and control linkage adjustments are okay. During test, transaxle should upshift
or downshift at about same speed as specified. See appropriate SHIFT SPEED SPECIFICATIONS
.
2. All shifts may vary slightly due to production tolerances or tire size. The quality of the shifts are more important. All shifts should be
smooth, responsive and with no slippage or engine flare. Slippage or engine flare in any gear usually indicates clutch or band problems.
3. The slipping clutch or band in a particular gear can usually be identified by noting transaxle operation in other selector positions and
comparing internal units which are applied in these positions. See CLUTCH & BAND APPLICATION
.
