Shock Absorber and Spring Assembly

Shock Absorber and Spring Assembly:

Disassembly

WARNING: All vehicles are equipped with gas-pressurized shock absorbers which will extend unassisted. Do not apply heat or flame to the shock absorbers during removal or component servicing. Failure to follow these instructions may result in personal injury.

WARNING: The spring is under extreme compression, care must be taken at all times. Failure to follow this instruction may result in personal injury.

CAUTION: The coil spring is coated with long-term corrosion protective paint. Do not damage the paint during component servicing.

CAUTION: Suspension fasteners are critical parts because they affect performance of vital parts and systems and their failure can result in major service expense. A new part with the same part number must be installed if installation becomes necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

1. Remove the shock absorber and spring assembly.

2. WARNING: Always wear safety goggles when using a spring compressor. Failure to follow these instructions may result in personal injury.

Position the shock and spring assembly in a suitable spring compressor.
3. Compress the spring enough to relieve the tension on the shock and spring assembly.

4. CAUTION: Do not use an impact wrench on the shock absorber rod nut.

NOTE: Use the holding feature to prevent the shock absorber rod from turning while removing the nut.

While holding the shock absorber rod, remove and discard the rod nut.
5. Remove the shock absorber assembly and spring lower seat.
6. Remove the dust boot and jounce bumper.
7. Remove the shock absorber upper mount and spring upper seat.
8. Carefully release the tension on the spring compressor and remove the spring.

Assembly
1. Install the lower spring seat, jounce bumper and dust boot onto the shock absorber.

2. WARNING: Always wear safety goggles when using a spring compressor. Failure to follow these instructions may result in personal injury.

Position the shock and spring assembly in a suitable spring compressor.
3. Install the spring, shock absorber upper mount and spring upper seat.
4. Align the arrow on the upper mount perpendicular to the center of the shock absorber lower mount.





5. Compress the spring enough to relieve the tension on the shock and spring assembly.
6. Position the end of spring within 0-10 mm (0-0.39 inch) of the upper spring mount.





7. NOTE: Before tightening the shock absorber rod nut, position the end of the spring within 0-10 mm (0-0.39 inch) of the step on the lower spring mount.

NOTE: Use the holding feature to prevent the shock absorber rod from turning while installing the nut.

Install the shock absorber rod nut.
^ Tighten to 115 Nm (85 ft. lbs).





8. Release the tension on the shock and spring assembly.
9. Install the shock absorber and spring assembly.
