Fig. 1 Tightening hose clamp on outer joint
^ Install pliers VAG 1682 as shown in illustration. Ensure that the jaws of the pliers seat in the corners (arrow B) of the hose clamp.
^ Tighten hose clamp by turning the spindle with a torque wrench (do not use pliers).
^ Tightening torque: 20 Nm (15ft. lbs.).
Notes:
^ Use torque wrench with a 5 - 50 Nm (3 - 37 ft. lbs.) range (e.g. VAG 133 1).
^ Ensure the the spindle thread is not tight. If necessary lubricate with MOS 2 grease
^ If the thread is tight e.g. dirty, the required tightening force for the hose clamp will not be achieved in spite of correct tightening torque settings.
Fig. 2 Pressing off outer constant velocity joint
^ Clamp drive axle in vise.
^ Remove the large hose clamp and pull back boot.
^ Screw special tool into end of joint until constant velocity joint can be removed from shaft.
Fig. 3 Venting joint boot
^ Only for rubber joint boot
^ A partial vacuum is sometimes created in the boot during installation.
^ This partial vacuum causes a crease in the boot when driving (see arrow).
^ It is therefore important to note the information:
^ Before tightening the hose clamp, equalize the pressure by lifting the boot.
