A torn CV axle boot is the most common cause of CV
axle failures. Look for grease on front suspension com-
ponents, inner tire sidewall or fender to indicate a pos-
sible torn boot. Inspect boots for cracks, holes, tears or
loose clamps. Dirty grease within the boot may indicate
damage to the CV axle joint. Replace the boot if it is
cracked or torn, has any holes or has loose clamps.
1. Remove CV axle assembly (see CV Axle Assembly
in this section).
2. Clamp the un−splined center section of the axle in a
vise.
3. Cut, remove, and discard damaged boot and boot
clamps.
4. Replace outboard boot as follows:
A. Use a soft brass or plastic hammer against the CV
joint and carefully drive the joint from the center shaft.
B. Clean old grease from CV joint and center axle.
C. Fit small clamp and boot over center axle.
D. Fill CV joint with approximately 1.5 oz (44 ml) of
Shell Gadus 1452 or equivalent low friction CV joint
grease.
E. Align CV joint with center axle splines and slide
against spring clip on shaft. Start the joint over the
spring clip by using a small screwdriver to collapse
the spring clip while pushing the joint onto the center
shaft.
F. Use a soft brass or plastic hammer against the
outboard joint housing and carefully drive the joint
onto the center shaft until spring clip is seated.
5. Replace inboard boot as follows:
A. Remove the outer retaining ring and pull the joint
housing from the CV joint.
B. Remove the inner retaining ring and pull the CV
joint from the center axle.
C. Clean old grease from CV joint, center axle and
joint housing.
D. Fit small clamp and boot over center axle.
E. Align CV joint with center axle splines and install
joint onto center axle. Install inner retaining ring.
F. Fill CV joint with approximately 1 oz (30 ml) of
Shell Gadus 1452 or equivalent low friction CV joint
grease.
G. Fit CV joint into joint housing and install outer re-
taining ring.
6. Fill boot with approximately 1.5 oz (44 ml) of Shell
Gadus 1452 or equivalent low friction CV joint grease.
7. Fit boot over grooves in center shaft and joint hous-
ing. Secure boot with clamps.
8. Install CV axle assembly (see CV Axle Assembly in
this section).
