3) Remove the strut mount and upper spring seat from strut.
4) Gradually decrease the compression force of compressor, and remove the coil spring.
5) Remove the dust cover and helper.
ASSEMBLY
1) Using a coil spring compressor, compress the coil spring.
NOTE:
Make sure that the vertical install direction of the coil spring is as shown in the figure.
2) Set the coil spring correctly so that its end face seats well in the spring seat as shown in the figure.
3) Install the helper and dust cover to the piston rod.
4) Pull the piston rod fully upward, and install the spring seat.
NOTE:
Position the upper spring seat as shown in the figure.
5) Install the strut mount to piston rod, and temporarily attach and tighten a new self locking nut.
6) Using a hexagon wrench to prevent strut rod from turning, tighten the new self-locking nut with ST.

Tightening torque:
55 Nm (5.61 kgf-m, 40.6 ft-lb)
7) Loosen the coil spring compressor carefully.
INSPECTION
Check the removed part for wear, damage and cracks, and then repair or replace it if defective.
STRUT
1) Check for oil leaks.
2) Move the piston rod up and down to check that it operates smoothly without any hitch.
3) Piston rod play
^ Measure the play as follows:
Fix the outer shell in place and fully extend the rod. Set a dial gauge at the end of rod L [10 mm (0.39 in)], and then read the dial gauge indication P1 while applying a force of W [20 N (2 kgf, 4 lbf)] to the threaded portion. Apply a force of 20 N (2 kgf, 4 lbf) from the opposite direction of "W", and then read the dial gauge indication P2.
Play limit (P1 + P2):
0.8 mm (0.031 in)
If the play exceeds limit, replace the strut.
STRUT MOUNT
Check the rubber part for deformation, cracks or deterioration, and then replace it with a new part if defective.
DUST COVER
If cracks or damage are found, replace it with a new part.
COIL SPRING
If a permanent strain is found, replace it with a new part.
HELPER
If major cracks or damage are found, replace it with a new part.
