Overhaul

1. Carefully clamp the gearbox in a vise with soft jaws.
2. Remove the tie-rod assembly.

3. Remove the boot bands and tube clamps. Pull the dust seals away from the ends of the gearbox.

4. Hold the steering rack with a 19 mm wrench and unscrew the rack end with a wrench.

5. Push the right end of the rack back into the cylinder housing so the smooth surface that rides against the seal won't be damaged.

6. Loosen the rack screw locknut and remove the rack guide screw.

7. Remove the disc washer, spring and rack guide from the gear housing.
