Pre-checking

Make sure that wheel alignment is correct. Refer to SPECIFICATIONS .
Verify that the steering gear is centered before removing the steering wheel.

Checking

Check that the steering wheel is in neutral position when driving straight ahead.
If it is not in neutral position, remove the steering wheel and reinstall it correctly.
If the neutral position is between two teeth, loosen tie-rod lock nuts. Turn the tie-rods by the same amount in opposite directions on both left and right sides.
