Removing and installing left drive shaft with (push-on) constant velocity slip joint
   
Removing and installing left drive shaft with (push-on) constant velocity slip joint
Special tools and workshop equipment required
t  Multipurpose tool -VW 771-
t  Support tool -T10038-
t  Drive shaft puller -T10382-
t  Torque wrench -V.A.G 1332-
t  Angle wrench -V.A.G 1756-

Removal:
  Caution
When removing and installing drive shafts, do not allow them to hang free and stop against joints due to excessive bending.
Removal:
–  Loosen drive shaft bolt at wheel hub:
t  Twelve-point head bolt with ribbing → Chapter
t  Twelve-point head bolt without ribbing → Chapter
  Caution
Wheel bearings must not be subjected to load after loosening bolt securing drive shaft at wheel hub.
If they have to support the weight of the vehicle they will be damages and their service life will be reduced.
It is not permissible to turn drive shaft bolt more than 90° anti-clockwise if vehicle is standing on its wheels.
Do not attempt to move the vehicle without the drive shafts fitted; this would result in wheel bearing damage. If a vehicle nevertheless has to be moved, comply with the following:
t  Install an outer joint instead of the drive shaft.
t  Tighten outer joint to 120 Nm.
–  Remove sound insulation (bottom) → Rep. gr.50.
–  Remove wheel.
   
–  Remove nuts -arrows-.
–  Pull wheel bearing housing with swivel joint out of suspension link.
–  Push drive shaft outer joint out of wheel hub by hand.
–  Secure drive shaft to prevent it from falling.

–  Position puller -T10382/1- behind constant velocity slip joint -1-.
Cut-out -arrow- of puller -T10382/1- must face constant velocity slip joint -1-.
  N40-10333
–  Install spindles -T10382/2- and traverse -T10382/3- on puller plate -T10382/1-.
–  Install multi-purpose tool -VW 771- on traverse -T10382/3-.
–  Pull out drive shaft with a couple of strikes of multi-purpose tool -VW 771-.
–  Remove drive shaft from vehicle.
Installation
Remove any paint residues and/or corrosion on thread and splines of outer joint.
–  Insert new retaining ring in groove in stub shaft on gearbox.
–  Lightly grease splines of stub shaft with universal grease -G 060 735 A2-.
–  Mesh outer and inner splines of gearbox and constant velocity slip joint.
–  Slide drive shaft into constant velocity joint to stop by hand.
–  Now push constant velocity joint onto stub shaft of gearbox with a »sudden, hard push«.
  Note
Never use a hammer or other driving tools.
–  Check that constant velocity slip joint is securely seated by pulling constant velocity slip joint against resistance of retaining ring.
  Caution
For this test, it is only permitted to pull on constant velocity slip joint and not on drive shaft.
–  Remove tensioning strap -T10038-.
–  Guide outer joint into wheel hub splines as far as possible.
  N40-10334
–  Bolt swivel joint to suspension link -arrows-.
  Note
Ensure that bellows are not damaged or twisted.
–  Install lower noise insulation → Rep. gr.50.
–  Tighten drive shaft bolt at wheel hub:
t  Twelve-point head bolt with ribbing → Chapter
t  Twelve-point head bolt without ribbing → Chapter
  Caution
During this step, vehicle must not be standing on its wheels.
The wheel bearing can be damaged by the weight of the vehicle if the bolt is loosened.
