Important: After installing the OTC 7045-B and before compressing the coil spring, ensure the retaining pin is thoroughly seated in the slot of the upper plate. Failure to do so may deform the pin and make the removal of
the tool from the coil spring difficult.
- Install OTC 7045-B coil spring compressor tool or equivalent to the coil spring through the hole in the lower control arm.

- Remove the coil spring insulator from the coil spring.
Installation Procedure
- Install the coil spring insulator to the coil spring.
- Install the OTC 7045-B coil spring compressor tool or equivalent to the coil spring and compress the coil spring.
Important: The flat end of the coil spring and the upper insulator goes up into the shock tower and the pointed end of the coil spring goes on the lower control arm. Align coil spring so that end of the coil spring is seated in
the pocket in the lower control arm.
- Install the coil spring and insulator to the lower control arm.
- Raise the lower control arm into position and place a suitable safety jack under the lower control arm rear leg near the bushing.

Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the lower control arm pivot bolt retaining nuts and washers.
