B. Rear Axle

1. Working through the level plug hole (1), carefully use a screwdriver to

spread the brake disks apart.

IMPORTANT! DO NOT damage the surfaces of the brake disks when spreading the

brake disks.

2. Using a feeler gauge, check the gap (2) between the brake disks (3). If the

gap is greater than .167" (4,25 mm), replace the brake disks.

NOTE: If the brake disks are worn beyond .167" (4,25 mm), the brake disk must be

replaced on both sides of the axle at the same time.

3. Repeat step 1 and step 2 for the other side of the axle.

4. Continue with step 6 of “B. Axle Oil Change” on page 134.
