Front Wheel Raised Toe

Front Wheel Raised Toe

The front wheel raised-toe measurement is determined from the wheel toe measured in the unladen position, and the wheel toe measured with the wheel raised 60 mm from the unladen position.

The front wheels must be bounced in order to check and set the front wheel toe-in curve. Special tools VAG 1925 and VAG 1925/3 are required for this work.

The front wheel raised-toe measurement must be checked each time the vehicle alignment procedure is carried out.





The front wheel raised toe must be checked if:
- The swing arm/track rod joint (-A- and -B-) has been loosened.
- Axle components and/or the body have been damaged in an accident.
- Car does not steer properly when travailing over uneven surfaces and when braking.





1. Attach special adjustment tool No. VAG 1925 with adapter tool No. VAG 1925/3, or equivalents, to front subframe bolts on both sides.

NOTE: If there are clearance problems when adjusting the adjustment tool, do not attach adapter until later.





2. Unscrew both threaded spindles just enough for them to touch front subframe bolts.
3. Position axle lift at front jacking points and jack up car about 70 mm (2-3/4 inch).

NOTE: When the car is jacked up, the wheels must not lose contact with the turntables.





4. Push cylinder up out of threaded spindles and secure with the locking bolt.
- Ensure that locking bolts (arrow) are positioned correctly and are properly inserted.
5. Lower car onto adapter (adapter tool No. VAG 1925/4, or equivalent is not applicable).
6. Refer to Specification for adjustment limits.

NOTE:
^ Add 0.20° to the toe-in value (setting value) of the left-hand wheel measured in the unladen position and compare with the toe-in reading indicated. Correct toe-in of the left wheel if necessary.
^ Add 0.20° to the toe-in value {setting value) of the right-hand wheel measured in the unladen position and compare with the toe-in reading indicated. Correct toe-in of the right wheel, if necessary.


EXAMPLE
+0.11° Actual toe-in measured in unladen position (setting value).
+0.20° Wheel toe correction (constant).
+0.31° Total.
Toe-in with the vehicle in the jacked-up state is therefore +0.31° ± 0.03° at the wheel in question.





7. Loosen clamping bolt -A-, 16 mm (0.62 inch).
8. Unscrew adjusting bolt -B- by about 4 mm (0.16 inch) and push track rod joint down as far as stop.
9. Screw in adjusting bolt -B- far enough so that calculated specified value is achieved.
10. Tighten clamping bolt -A- to 45 Nm (33 ft. lbs.) and check reading.
11. Tighten adjusting bolt -B- to 7 Nm (62 inch lbs.).
12. After the car is again in the unladen position, bounce the springs several times.

NOTE: The figure that applies for the subsequent check of toe-in in the unladen position is the checking value, refer to Specifications.
