I Final Drive
4 Support inner hub with BMW special tools 26 1 110 and
press axle shaft out of joint using BMW special tool 21 2 120.
- Clean all old lubricant off shaft splines and inner joint splines.
If the CVjoint must be disassembled for cleaning and inspec-
tion, be sure to matchmark inner and outer race and interme-
diate ball cage. This allows reassembly
ofparfs in their
original positions.
NOTE-
To inspect a CVjoint, clean away the grease and loolc forgall-
ing, pitting, and other signs of wear orphysical damage. Pol-
ishedsurfaces or visible ball traclts alone are not necessarily
cause forreplacement. Discoloration due to overheating indi-
cates
laclt of lubrication.
- Slide CV joint boot onto axle shaft
- Apply LoctiteO270 or an equivalent heavy-duty loclting corn-
pound to drive axle splines. Position new CV joint on shaft so
that raised or taller side of hub is facing shaft.
WARNING-
Do not let the locking compound contact the balls in the joint.
Apply only a thin coat to cover the splines.
While supporting axle shaft with BMW special tool
33 2 130
press inner hub of CV joint onto shaft. Install a new circlip.
- Install new boot clamps.
- Use sealing gel to seal dust cover to CV joint prior to reinstal-
lation.
NOTE-
* Do not let the ball hub pivot too far in the outer ring of the
joint.
Tlie balls will fa1 out.
Before installing each small boot clamp be sure to
'burp"the
boot by flexing the CVjoint. A small screwdriver inserted be-
tween the boot and the axle shafl will help the process.
