STRUT ASSEMBLYDISASSEMBLY AND REASSEMBLY
Disassembly Steps 1-8:
DISASSEMBLY SERVICE POINTS
[[A]] STRUT NUT REMOVAL
1. Install the spring compressor (special tool: MB991793) to attachment A (special tool: MB991795) as shown in the figure.
2. Set the strut assembly to the following special tools.
^ Spring compressor (M13991793)
^ Attachment A (M13991795)
^ Upper plate (M13991794)
^ Fixture (M13991830)
NOTE: Use the bolts and nuts removed from the vehicle to secure the strut assembly and tighten them lightly by hand.
3. After setting the strut assembly, operate the spring compressor and compress the coil spring by approximately 5 mm.
CAUTION: The lock nut for the piston rod inside the strut may be loose. Do not use the impact wrench to loosen the strut nut.
4. Use the following special tools to loosen the strut nut.
^ Wrench (M13991681)
^ Socket (M13991682)
[[B]] STRUT ASSEMBLY DISPOSAL
CAUTION: Wear the protective glasses. Although the gas is harmless, drilling chips may be blown out by the gas.
Before disposal of the strut, place the strut on the level surface with the piston rod extended, and make a hole of approximately 3 mm in diameter at the point shown in the figure to discharge the gas.
REASSEMBLY SERVICE POINTS
]]A[[ COIL SPRING INSTALLATION
Install the coil spring to align the bottom with the shape of the strut spring seat.
]]B[[ UPPER SPRING SEAT INSTALLATION
Align the D-shaped hole with the D (cut-off) of the strut, and install the marked part shown in the figure facing the inside of the vehicle.
]]C[[ STRUT NUT INSTALLATION
1. Check that both of the coil spring ends align with the spring seat groove correctly.
2. Align the strut spring seat hole with the upper spring seat hole.
CAUTION: Be careful that the hand is not pinched by the coil spring when aligning the piston rod with the hole of upper insulator while compressing the coil spring.
3. While passing the strut piston rod through the hole of upper insulator by hand, slowly compress the coil spring by the following special tools.
^ Spring compressor (MB991793)
^ Attachment A (MB991795)
^ Upper plate (MB991794)
^ Fixture (MB991830)
CAUTION: The lock nut for the piston rod inside the strut may be loose. Do not use the impact wrench to tighten the strut nut.
4. Use the following special tools to tighten the strut nut to the specified torque.
^ Wrench (MB991681)
^ Socket (MB991682)
GREASE: Shell Retinax Grease CL0
Tightening torque: 61 ± 9 Nm (45 ± 7 ft-lb)
INSPECTION
^ Check the bearing for wear or rust.
^ Check the rubber parts for damage or deterioration.
^ Check the spring for deformation, deterioration or damage.
^ Check the shock absorber for deformation.
