Figure 15-17. Some pressed-on bearings must be removed
with a hydraulic press, driver, and the proper adapters. Never
use excessive pressure on the housing or hub, as this can
cause them to break. (Chrysler)
Figure 15-20. To gain access to some bearings, the CV axle
and the steering knuckle assembly must be removed from the
vehicle as a unit. The components are then separated with a
puller. (Subaru)
Figure 15-19. Bearings must be carefully removed. A hydraulic
press, with a driver and the proper adapter, is often used to
remove bearings. Always consult the service manual for exact
procedures. (Honda)
Figure 15-18. Some seals must be removed using a hydraulic
press, driver, and suitable adapters. Other seals are held in
place by clips. A few seals will be pressed out when the bearing
is removed. (Chrysler)
In some cases, the bearing carrier or the steering
knuckle uses a seal that must be pressed from the knuckle
or carrier housing before the bearing can be removed,
Figure 15-18. Once the seal is removed, the bearing can
be pressed out of the housing, Figure 15-19.
Some CV axle assemblies are pressed into the steering
knuckle or carrier. In these cases, the shaft must be
removed from the knuckle or carrier housing with the
proper puller. See Figure 15-20. After the shaft is removed,
the outboard bearing can be removed from the housing.
If tapered roller bearings are used, the bearing races must
be replaced when the bearings are replaced. Figure 15-21
shows a driver being used to remove bearing races from a
typical housing.
Some bearings are pressed into the housing with a
spacer between them to maintain proper bearing position.
If you replace the bearings or the housing in this type of
system, you must select the proper replacement spacer or
bearing problems will result. A few systems use a collap-
sible spacer, similar to the collapsible spacer used in rear-
wheel drive pinions. Refer to the manufacturer’s service
manual for exact replacement procedures.
Install new bearings, races, and seals with the proper
driver and a hydraulic press. See Chapter 4 for more
