Pinion Seal, Dust Seal and Bearing/Annulus Assembly

^ Tools Required:
- J 29810 Stub Shaft Seal Protector, Or Equivalent
- 14 mm Crowfoot Wrench


Remove or Disconnect
1. Rack and pinion steering assembly from vehicle.






2. Adjuster plug lock nut (15) from adjuster plug.
3. Adjuster plug from gear assembly (30).
4. Adjuster spring and rack bearing.
5. Retaining ring (17) from valve bore of gear assembly (30).






6. Dust cover (33) from bottom of gear assembly (30).

CAUTION: Stub shaft must be held to prevent damage to the pinion teeth.

7. Hex lock nut (32) from lower end of pinion and valve assembly, while holding stub shaft with 14 mm Crowfoot Wrench.

CAUTION: DO NOT hammer or pound on pinion and valve assembly. This will cause damage or loosen the drive pin.

NOTE: When performing the following procedure, do not remove pinion and valve assembly from gear assembly. Press pinion and valve assembly only far enough to allow removal of bearing/annulus and seal. Pinion and valve assembly removal is not required.









8. Use an arbor press. Press on threaded end of pinion until it is possible to remove stub shaft, spool shaft seal (20), and stub shaft bearing/annulus assembly (21).


Install or Connect

CAUTION: If the stub shaft is not held, damage to the pinion teeth will occur.

1. Hex lock nut (32) onto pinion, while holding the valve stub shaft.
^ Tighten hex lock nut (32) to 30 Nm (22 ft. lbs.).
2. Oust cover (33) to gear assembly (30).
3. Stub shaft bearing annulus assembly (21) onto valve stub shaft.
4. Stub Shaft Seal Protector onto valve stub shaft.
5. Apply a small quantity of grease on seal (20).
^ Spool shaft seal (20) over protector and into gear assembly (30).
6. Retaining ring (17) into groove in gear assembly (30).
7. Lubricate stub shaft and dust seal area with grease.






8. Coat rack bearing, adjuster spring and adjuster plug with lithium base grease and install in gear assembly (30).
^ With rack centered in the gear assembly (30), turn adjuster plug clockwise until it bottoms in the gear assembly, then back off 50° - 70° (approx. one flat). Check rotational torque on pinion. Maximum pinion preload torque is 1.8 Nm (16 inch lbs.).
9. Adjuster plug lock nut (15) to adjuster plug. Tighten firmly against gear assembly while holding adjuster plug stationary.
10. Rack and pinion assembly into vehicle.
