Wheel Alignment 2 illustrations ~370 words

WHEEL ALIGNMENT WORK SEQUENCE

Before starting wheel alignment, read PRELIMINARY CHECKS . Perform wheel alignment procedure in the following order.

  1. Carry out axial wheel run-out compensation. Since some wheel run-out is allowable, checking alignment without first compensating for axial wheel run out may indicate that the toe-in tolerance is already exceeded. If this is the case it is not possible to set toe-in without first compensating for wheel run-out.
  2. Install brake pedal depressor.
  3. Check front axle camber. Adjust as necessary.
  4. Check rear axle camber. Adjust as necessary.
  5. Check rear axle toe. Adjust as necessary.
  6. Check toe-in curve on front axle. Adjust as necessary.
  7. Check front axle toe with vehicle at curb weight. Adjust as necessary.

  4. LOOSEN, but do not remove bolts No. 1, No. 2, No. 5, No. 6, No. 7 and No. 8. Turn Camber Adjuster (VAG 1941) bolt 2 until camber specifications are within tolerance. (Scheme 2)
  5. Tighten NEW bolts No. 7 and No. 8 to 81 ft. lbs. (110 N.m). Then tighten an additional 1/4 (90 degrees) turn.
  6. Remove Camber Adjuster (VAG 1941) from subframe.
  7. Tighten NEW forward bolts No. 5 and No. 5 to 81 ft. lbs. (110 N.m). Then tighten an additional 1/4 (90 degrees) turn.
  8. Tighten bolt No. 1, No. 2, No. 3 and No. 4 to 44 ft. lbs. (60 N.m).
  9. Recheck all wheel alignment settings.

CASTER ADJUSTMENT

Before checkingalignment, read PRELIMINARY CHECKS and WHEEL ALIGNMENT WORK SEQUENCE Front and rear caster are not adjustable. If caster is not as specified, locate and replace damaged or worn suspension parts.

TOE ADJUSTMENT

Note. Before checking and adjusting front axle toe, check if toe-in curve needs to be checked or adjusted. See TOE-IN CURVE .
