For 1990-2009 cars

1. Remove the strut housing tie bar (1) by loosening the four through-bolts (2) and removing the left and inboard strut nuts (3).
2. Remove the remaining top strut nuts and the washers (4 & 7).
3. Lift the front of the vehicle by the body to separate the strut (5) from the inner wheelhouse.
4. Drill two 11/32 inch holes (6) at the front and the rear of the oval strut mounting hole on the left and the right strut towers.
5. File the excess metal in order to make the slotted holes.
6. Paint the exposed metal with a rust preventative primer and paint.
7. Lower the front of the vehicle.
8. Reinstall the tie bar on the left and the right inboard strut studs. Install the strut attaching nuts, but do not tighten the strut attaching nuts at this time.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

9. Adjust the caster by moving the top of the strut forward or backward. A 1 mm (0.040 in) position change at the tower is about equal to 0.1 degree change in the caster. Refer to Wheel Alignment Specifications .

Tighten
Tighten the strut attaching nuts to 24 N·m (18 lb ft) and the tie bar through-bolts to 37 N·m (27 lb ft).
