DISASSEMBLY SERVICE POINTS

[[A]] STRUT NUT (JAM NUT) REMOVAL





1. Install special tool MB991795 to special tool MB991793 as shown in the illustration.





2. Set the strut assembly to the following special tools.

- MB991793: Spring Compressor
- MB991794: Upper Plate
- MB991795: Attachment A
- MB991830: Fixture

NOTE:
Set the strut assembly by using the bolt and nut that are removed from the vehicle. When installing the bolt and nut, lightly tighten them by hand.

3. Compress the coil spring approximately 5 mm (0.20 inch) using the spring compressor.









4.
CAUTION:
Do not use an impact wrench to tighten the strut nut, otherwise the strut nut will be damaged. Vibration of the impact wrench will cause the valve inside the strut to drop out.

For 2.4L engine models, use special tool MB991682 to secure the strut, and then remove the strut nut (jam nut) using special tool MB991681.
For 3.8L engine models, use a hexagon wrench and a pipe to secure the strut, and then remove the strut nut (jam nut) using special tool MB991681.

[[B]] STRUT DISPOSAL

WARNING:
Wear goggles when drilling to protect your eyes from flying metal debris.





The gas must be discharged from the strut before discarding it. Place the strut horizontally with its piston rod extended. Then drill a hole of approximately 3 mm (0.12 inch) in diameter at the location shown in the illustration and discharge the gas.

ASSEMBLY SERVICE POINTS

]]A[[ LOWER SPRING PAD INSTALLATION





Engage the three lugs of the spring lower pad into the holes on the front suspension strut as shown.

]]B[[ STRUT INSULATOR ASSEMBLY INSTALLATION





If the upper plate and lower plate of the strut insulator have been disassembled, assemble them as shown.

]]C[[ STRUT NUT (JAM NUT) INSTALLATION

1. Ensure that the bearing is seated correctly.





2. WARNING:
When the strut piston rod is positioned to the hole of strut insulator with compressing the coil spring, be careful that your hand is not jammed by the coil spring.

Compress the coil spring slowly using the following special tools, penetrating the strut piston rod to the hole of strut insulator.

- MB991793: Spring Compressor
- MB991794: Upper Plate
- MB991795: Attachment A
- MB991830: Fixture
3. While the coil spring is being compressed by the special tools, temporarily tighten the strut nut (jam nut).





4. Ensure that the arrows on the strut bracket center and the strut insulator are positioned as shown.









5.
CAUTION:
Do not use an impact wrench to tighten the strut nut, otherwise the strut nut will be damaged. Vibration of the impact wrench will cause the valve inside the strut to drop out.

For 2.4L engine models, using special tools MB991681 and MB991682, tighten the strut nut (jam nut) to 65 ± 5 Nm (48 ± 4 ft-lb).
For 3.8L engine models, using special tool MB991681, a hexagon wrench and a pipe, tighten the strut nut (jam nut) to 65 ± 5 Nm (48 ± 4 ft-lb).
