Installation of a New Spring
1. If replacing the spring, remove the old spring from the strut tool. Install the new spring in the tool, assembling
the locking jaws as shown in Figure 1. Compress the spring.
2. Align the lower spring tip in its receptacle in the lower platform. Replace the top mount. Attach the piston
rod nut, and torque it to the specifications listed in the vehicle service manual.
3. Check the alignment of both spring coil tips to the mounting platforms. Decompress the spring.
4. Follow the manufacturer's procedure to reinstall the strut assembly.
Maintenance
Item numbers refer to the parts list.
1. Use vehicle chassis grease to keep the forcing screw
lubricated.
Reassembly Procedure
Follow this procedure if it is necessary to remove the forcing
screw (Item No. 2), top trunnion (No. 12), or the bottom
trunnion (No. 11) for repair or replacement.
1. Ensure the trunnions (Item Nos. 11 and 12) are driven
in approximately one inch from the edge of the forcing
screw's bottom threads and one inch from the edge of
the top threads, respectively, before remounting the arms
onto the trunnions. See Figure 5.

Tech Tip
The top trunnion has been designed as an indicator of
spring compression. When the top trunnion is centered as
shown in Figure 4, the tool is not applying any force to the
strut assembly.
