WARNING
When loosening or tightening an axle nut, make sure the vehicle is on the ground. The amount of torque required could cause the vehicle to fall off jackstands.


NOTE
When removing the right axle shaft, you must detach the exhaust pipe from the manifold and the transaxle bracket. Be sure to buy a new exhaust flange gasket.

  1. With the vehicle on the ground, remove the front axle nut.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Raise and safely support vehicle and remove the front wheels.
  6.  
  7. Remove the ball joint clamping bolt and push the control arm down, away from the ball joint.
  8.  
  9. If necessary, carefully loosen the halfshaft in the hub using a brass drift and hammer.
  10.  
  11. Remove the socket head bolts from the transaxle drive flange.

  1. Remove the halfshaft from the drive flange and support it below the flange. Do not let it hang by the outer CV-joint, or the joint may fall apart.
  2.  
  3. Remove the assembly from the vehicle.

To install:

  1. Fit the halfshaft to the drive flange and install the bolts. It is not necessary to tighten them yet.
  2.  
  3. Apply a thread locking compound to the outer 1 / 4 inch of the spline. Slip the spline through the hub and loosely install a new axle nut.
  4.  
  5. Assemble the ball joint and tighten the nut and bolt to 37 ft. lbs. (50 Nm).
  6.  
  7. Install the wheel and hold it to keep the axle from turning. Tighten the drive flange bolts to 33 ft. lbs. (45 Nm).
  8.  
  9. With the vehicle on the ground, tighten the axle nut to 195 ft. lbs. (265 Nm) on Golf and Jetta, or 175 ft. lbs. (240 Nm) on other models.

1995-99 Cabrio, 1993-99 Golf and Jetta

Three suspension systems offered on the A3 platform. A base suspension, plus suspension, and triple roller joint type. An easy way to determine which suspension you have is to note the type of nuts used to fasten the inner Constant Velocity joint to the inner transaxle drive flange. On the base suspension a standard six point hex nut was used. The plus suspension had twelve point self-locking nut. Triple-roller joint style systems are used on vehicles with a four cylinder power plant and an automatic transmission.

WARNING
Cover all exposed joints to avoid contamination from entering the joint which will lead to joint failure.

To install:


NOTE
Two types of hubs were used on this system. The standard (non-modified) hub used a thread sealer such as Loctite®. Later a modified hub was installed with a stronger hub nut and modified splines. This hub does not require a thread sealant. Please note the following torque specifications below.

  1. Tighten the outer CV joint to wheel hub bolt to 148 ft. lbs. (200 Nm) on vehicles with a modified hub.
  2.  
  3. Tighten the outer CV joint to wheel hub bolt to 66 ft. lbs. (90 Nm) on vehicles with a modified hub.
  4.  
  5. Tighten the ball joint to control arm bolts to 26 ft. lbs. (35 Nm).
  6.  
  7. Tighten the inner CV joint to drive flange bolts to 33 ft. lbs. (45 Nm).
  8.  

TRIPLE Roller Joint

WARNING
When loosening or tightening an axle nut, make sure the vehicle is on the ground. The amount of torque required could cause the vehicle to fall off jackstands.

  1. Pry off the dust caps and loosen the axle nut. Do not remove the nut at this point.
  2.  
  3. Install an engine support brace across the top of the engine.
  4.

CV-JOINT AND BOOT OVERHAUL



The constant velocity joints (CV-joints) can be disassembled for cleaning and inspection but they cannot be repaired. All parts are machined to a matched tolerance and the entire CV-joint must be replaced as a unit. On Golf and Jetta, the CV-joints are different on the left and right sides and cannot be interchanged.

  1. Raise and safely support the vehicle and remove the halfshaft.
  2.  
  3. Pry open and remove the boot clamps with a pair of wire cutters.
  4.  
  5. With the halfshaft securely clamped in a vise, the outer CV-joint can be removed by sharply rapping out on the joint with a plastic hammer. The joint will snap off of the circlip and slide off the axle.
  6.  
  7. To remove the inner joint, remove the circlip from the center and slide the joint off the axle.
  8.  
  9. Both boots can be removed after removing the CV-joint
  10.  

To install:

  1. Always replace both circlips and make sure the CV-joint is clean before installation. Wrap a piece of black electrical tape around the shaft splines and slip the inner clamp and the boot onto the shaft.
  2.  
  3. Remove the tape and install the dished washer with the concave side out so it acts as a spring pushing the CV-joint out. On the outer joint, install the thrust washer and a new circlip.
  4.  
  5. To install the outer joint, place it onto the spline and carefully tap straight in on the end with a plastic hammer. The joint will click into place over the circlip.
  6.  
  7. To install the inner joint, slide it onto the spline and push in enough to allow the circlip to fit into the groove in the axle shaft.
  8.  
  9. Pack the CV-joint with special CV-joint grease. DO NOT use any other type of grease.
  10.  
  11. Pack any remaining grease into the boot and install the clamps on the outer boot.
