FRONT SUSPENSION – STRUT ASSEMBLY33A3
CAUTION
(1) To compress the coil spring securely, ensure that the
special tool is extended as far as the spring will allow,
then fitted evenly to the coil spring.
(2)There is a danger of special tool damage, so do not use
an impact wrench.
2. Using the following special tools, release the selflocking nut.
• Special spanner (MB991367)
• Pin (MB991385)
CAUTION
There is a danger of the lock nut inside the strut piston rodworking loose, so when loosening the selflocking nut, do
not use an impact wrench.
Important note on assembly
Fitting selflocking nut
1. With the coil spring compressed with the special tool,
temporarily tighten the selflocking nut.
2. Match up strut assembly hole in lower spring seat, and hole in
upper spring seat.
Remarks
Using a lever to align the holes can make this job easier.
3. Match both tips of coil spring precisely with the slots on the
spring seats, and release the special tool.
4. Using the special tool, tighten the selflocking nut to the
