15. Remove RH front axle cotter pin, then loosen axle nut with power tool.
16. Remove both RH and LH mounting bolt and nut that clamps lower steering knuckle to transverse link (lower control arm) ball joint with power tool. NOTE: Ball joint stud to steering knuckle fit is not a taper fit but is a slide fit, so no ball joint separator is needed.
17. Using a puller (or other suitable tool), push drive shaft end from out of wheel hub/steering knuckle assembly. CAUTION: When removing drive shaft, do not apply an excessive angle to drive shaft joint. Also be careful not to excessively extend slide joint.
18. Remove RH axle support bearing to support bracket bolts.
19. Remove RH axle from transaxle.
20. Remove propeller (drive) shaft.

22. Remove O2 sensor connector bracket.
23. Unbolt the return-side (low pressure) power steering tube brackets from front suspension member.
24. Unbolt heat shield from crossmember and remove.
25. Remove 2 mounting bolts and nut of steering gear assembly from front suspension member.
26. Support steering gear assembly up with a cord or an equivalent.
27. Firmly support transaxle assembly with pole jacks or suitable tools as follows: Place one jack under the transmission pan area. Place another jack under the transaxle differential area. CAUTION: When setting the transmission jack, be careful not to allow it to collide against the drain plug.
28. Firmly support front and rear of front suspension member (powertrain cradle frame) along the vehicle centerline with suitable jacks.
29. Remove CVT rear mounting insulator bolts.
30. Remove LH (bank 1, front) engine mounting insulator bracket mounting bolts from suspension member.
31. Remove RH (bank 2, rear) engine mounting insulator bracket mounting bolts from suspension member.
32. Remove front suspension member stays, then front suspension member nuts.
33. Gradually lower the front suspension member pole jacks no more than 4" in back and 2 1/2" in front, to the height where the transfer assembly can be removed. CAUTION: For stability and ease of reassembly don't lower the suspension member off the body mounting studs all the way.
34. Disconnect RH (bank 2, rear) engine mounting insulator harness connector.
35. Remove power steering hose bracket from RH (bank 2, rear) engine mounting insulator.
36. Remove RH (bank 2, rear) engine mounting insulator mounting bolts (upper side) and insulator.
37. Remove RH (bank 2, rear) engine mounting insulator bracket mounting bolts from transfer assembly, then remove bracket.
38. Remove RH (bank 2, rear) exhaust manifold cover. NOTE: It is not necessary to remove the exhaust manifold for this procedure.
39. Apply rust penetrant to then remove RH (bank 2, rear) three-way catalyst mounting flange TOP REAR nuts.
40. Apply rust penetrant to then remove RH (bank 2, rear) three-way catalyst mounting flange BOTTOM FRONT bolts, and remove the three-way catalyst. CAUTION: Catalyst internals are very fragile. Handle carefully to avoid any breakage or shock to three-way catalyst.

Scheme 97

Scheme 98

1. If the tooth contact is near the face (face contact), or near the heal (heel contact), thin the pinion sleeve shims to move the drive pinion closer to the drive gear. Refer to «PINION SLEEVE SHIM»(ref-234001-S13338120302006052800000) .
2. If the tooth contact is near the flank (flank contact), or near the toe (toe contact), thicken the pinion sleeve shims to move the drive pinion farther from the drive gear. Refer to «PINION SLEEVE SHIM»(ref-234001-S13338120302006052800000) .
