Removing the brake drum/disc and hub
Removing the brake drum together with the hub. Outer wheel bearing (1) should be held with a finger.
To check the rear wheel bearings for wear or damage, place the vehicle on jack stands and grasp the wheel from both sides and push and pull it as shown illustrations. Excessive play indicates damaged bearings. For the second check, quickly rotate the wheel several times and note the noises.
Too much play at the first check may indicate poor wheel bearing adjustment. To determine if the bearings have too much axial play, this can be checked after unscrewing the rear wheels. To do this, install a dial indicator on the rear suspension and place a dipstick on the outer edge of the brake drum or the outer side of the hub. Move the drum back and forth and take readings on the indicator. If the value exceeds 0.05 mm, the bearings must be replaced, as there is no possibility of adjustment. The hub bearings are maintenance free. Since the hub and bearing must be replaced together when removed, it is not worth removing the hub without a special reason.
1. Knock off the grease cap. Rotate the brake drum to evenly knock off the cap. Wipe off any excess grease from the hub nut.
2. Remove the cotter pin from the nut and loosen the hub nut.
3. Put the rear of the car on stands and remove the wheel.
4. Completely unscrew the hub nut.
5. With disc brakes installed, remove the brake caliper without unscrewing the brake hose.
6. Remove the brake drum or brake disc and remove the hub from the axle. If the hub is very tight, try using a puller. The brake drum can be left on the hub. When removing the brake drum or hub, hold the outer hub bearing with both thumbs to prevent it from falling out (see illustration). If removed, the bearing and hub must be replaced together.
Installing the wheel bearing
When installing the hub, proceed in reverse order. Consider the following:
1. Slide the hub drum or hub onto the axle and tap in completely with a plastic mallet.
2. Screw on a new nut (with puck) on the hub axle and tighten with a force of 186-255 Nm. Fasten the nut.
3. Drive the hub grease cap onto the hub.
4. Install the wheel, lower the car.
