6. Install the filler plug. Tightening torque 40-53 N.m (29-39 ft.lbf)

Scheme 4

1. On level ground, jack up the vehicle and support it on safety stands.
2. Drain the differential oil. NOTE: For easier installation, do not depress the brake pedal after removing the brake caliper component.
3. Remove the brake caliper component, then suspend the brake caliper component using a rope.
4. Remove the lower arm installation bolt and nut.
5. Pull the rear hub support from the drive shaft. NOTE: If the drive shaft will come out of the rear hub support easily, install a discarded nut onto the drive shaft so that the nut is flush with the end of the drive shaft. Tap the nut with a copper hammer to loosen the drive shaft from the wheel hub.
6. Remove the drive shaft from the differential. (See «DRIVE SHAFT REMOVAL NOTE»(/mazda/mx-5/nb-2001-2005/remont/axle-shafts/#drive-shaft) .)
7. Remove the oil seal.
8. Apply lithium-based grease to the new oil seal lip and install it using the SST.
9. Install a new clip onto the drive shaft. (See «DRIVE SHAFT INSTALLATION NOTE»(/mazda/mx-5/nb-2001-2005/remont/axle-shafts/#drive-shaft) .)
10. Install the lower arm installation bolt and nut. Tightening torque 54-76 N.m (40-56 ft.lbf)
11. Install the brake caliper component. Tightening torque 50-68 N.m (37-50 ft.lbf)
12. Add the specified oil. (See «DIFFERENTIAL OIL REPLACEMENT».)
13. Adjust the rear wheel alignment.

Scheme 5

1. Drain the differential oil.
2. Remove the crossmember bracket. (See «CROSSMEMBER BRACKET REMOVAL/INSTALLATION».)
3. Remove the main silencer. (See «EXHAUST SYSTEM REMOVAL/INSTALLATION»(/mazda/mx-5/nb-2001-2005/remont/exhaust/#exhaust-system) .)

1. Disconnect the wire harness from the PPF.
2. Support the transmission with a jack.
3. Remove the PPF bracket.
4. Remove the differential-side bolts, and pry out the spacer.
5. Remove the differential mounting spacer. CAUTION: Removing the PPF spacers will reduce the performance of the PPF. Do not remove the PPF spacers. If the spacers are removed, replace the PPF as a component.
6. Remove the transmission-side bolts, and remove the PPF. NOTE: If the sleeve cannot be removed easily, tap the side of sleeve with a plastic hammer.
7. Remove the sleeve.
8. To prevent damaging the fire wall and engine mount, support the transmission as follows. Prepare a steel plate (as shown in the figure), a wooden block, bolts (M8x1.25), and washers. Install a wooden block as shown in the figure.

1. Support the differential using a jack.
2. Lower the differential and move it forward.
