2. Checking and adjusting wheel alignment requires specialized equipment, so we recommend entrusting this work to a specialist.
3. If, as a result of some work on the steering system, the alignment of the tie rods has been knocked out of alignment, you can pre-adjust the toe-in so that you can drive the car to the nearest workshop, where they will accurately adjust the toe-in.
4. Toe-in is the difference between the distance between the wheel rims, measured at the front and rear at the hub level. A special template can be made to check this distance with the wheels aligned exactly in the center. The front wheel toe-in should be 3-4 mm.
5. If adjustment is necessary, proceed as follows.
6. Early models without lock nuts on the tie rod ends. Loosen the rubber boot clamp on the inner end of the rod and bend the boot back to expose the inner hinge of the rod. Loosen the lock nut (see B/Figure 9.33) and turn the inner ball joint cup to change the length of the rod as required. Rotating the ball joint by half a turn changes the toe-in on the rim of the corresponding wheel by 0.65 mm. If you need to change the toe-in by a significant amount (i.e. turn the hinge cup more than half a turn), adjustments should be made on both rods in equal proportions in order to maintain the symmetry of the steering geometry. After adjusting the toe-in, tighten the lock nut to the required torque, holding the ball joint cup from rotating. Do the same for the second rod, install the rubber boots in place and secure them with clamps. For correct installation of rubber boot clamps, see. in the previous section.

7. Latest models with tie rod end locknuts. Loosen the lock nuts and screw the tie rods into the ends or unscrew them to achieve the desired front wheel alignment. Rotating one tie rod by half a turn changes the toe-in on the corresponding wheel by 1 mm. In this case, if the correct toe-in requires rotating the tie rod more than half a turn, the adjustment should be made equally on both tie rods. Check that the bottom surface of the ball joints is horizontal and tighten the locknuts to the specified torque.
8. We would like to emphasize once again that in the absence of special equipment, this adjustment should be considered preliminary, and at the first opportunity the car should be taken to a workshop where the toe-in will be checked and precisely adjusted.
