Volkswagen Tiguan Service and Repair Manual: Drive Axles with Triple Roller Joint AAR3300i, Mounted in Transmission, Removing and Installing

Special tools and workshop equipment required

• Drive Axle Wedge Tool -T10161-
• Drive Shaft Remover -T10520-
• Torque Wrench 1332 40-200Nm -VAG1332-

Caution

When disassembling and performing repairs on a vehicle, the drive axles must not hang down loosely and contact the stops in the joint by over bending.

Removing

• Loosen the drive axle bolt on the wheel hub:
  • Twelve-point bolt with ribs.
  • Twelve-point bolt without ribs.

Caution

The wheel bearing must not be under load when the drive axle threaded connection on the wheel side is loose.

If the wheel bearings are under the load of the vehicle weight, the wheel bearing will be damaged. This reduces the service life of the wheel bearings.

The drive axle bolt may be loosened maximum 90º when the vehicle is standing on its wheels.

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If a vehicle must be moved, be sure to note the following:

• Install an outer joint in place of the drive axle.
• Tighten the outer joint to 120 Nm.

 

• Remove the wheel.
• Remove the lower noise insulation.
• Remove the nuts -arrows-.
• Remove the wheel bearing housing with the ball joint from the control arm.
• Pull the drive axle out of the wheel hub and tie it securely to the body.

If the drive axle cannot be pulled out of the wheel bearing, then the drive axle can be pushed out of the wheel bearing using the Drive Shaft Remover -T10520-.

Before using the Drive Shaft Remover -T10520-, make sure that the thrust piece -1- is installed.

Using the Drive Shaft Remover -T10520-:

• Secure the Drive Shaft Remover -T10520--1- with three wheel bolts -2- on the wheel hub, so that the drive axle -3- can be pressed out.

• Follow the specified sequence exactly.

1. Tighten the knurled nut -1- hand-tight.
2. Only turn the bolt -2- using a wrench and press out the drive axle using the Drive Shaft Remover -T10520-.

Note

At the end of the tasks or to set back, the spindles must be brought back into the original position so that the hydraulic operation can be used.

• Attach Drive Axle Wedge Tool -T10161- between transmission housing and triple roller joint.
• Press inner joint out of transmission via a hammer blow on the Drive Axle Wedge Tool -T10161-.
• Remove the drive axle.

Installing

• Insert new circlip into groove of joint piece bolt.
• Engage the outer and inner splines of joint and transmission.
• Grab the drive axle by hand and push it into the joint up to the stop.
• Now slide the joint into the transmission with a "jerk".

Slide path in joint piece can be used for this "tug". When doing this, do not pull the drive axle too far out of the joint.

Note

Do not use a hammer or a knocking tool under any circumstances!

• Check drive axle for secure fitting in transmission by pulling joint piece against resistance of the securing ring.

Caution

For this check, do not pull on the drive axle, but rather only on the joint.

• Insert outer joint as far as possible into wheel hub splines.
• Attach the ball joint to the control arm -arrows-.

Note

Make sure the ball joint boot is not damaged or twisted.

• Install the lower noise insulation.
• Tighten the drive axle bolt to the wheel hub:
  • Twelve-point bolt with ribs.
  • Twelve-point bolt without ribs.

Caution

The vehicle must not be resting on the wheels when doing so.

When the bolt is loose, the wheel bearing can be damaged by the vehicle's weight.

Difference between A Twelve-Point Bolt with Ribs and A Twelve-Point Bolt without Ribs

The contact surfaces -arrow A- and -arrow B- are different on the two-point bolts.

1. Twelve-point bolt with ribs -arrow A-
2. Twelve-point bolt without ribs -arrow B-

• Install the wheel and tighten.
