Suspension Spring ( Coil / Leaf ): Service and Repair
Shock Absorber and Spring AssemblySpecial Tool(s):
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.
CAUTION: Do not tighten the lower shock nut until the installation procedure is complete and the weight of the vehicle is resting on the wheel and tire assemblies.
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Remove and discard the shock absorber and spring assembly upper nuts.
^ To install, tighten to 40 Nm (30 lb-ft).
3. Remove and discard the tie-rod end nut.
^ To install, tighten to 150 Nm (111 lb-ft).
4. Using the special tool, separate the upper ball joint from the wheel knuckle.
5. Remove and discard the upper ball joint nut.
^ To install, tighten to 115 Nm (85 lb-ft).
6. Remove and discard the shock absorber and spring assembly lower nut and bolt.
^ To install, tighten to 475 Nm (295 lb-ft).
7. Using the special tool, disconnect the upper arm from the wheel knuckle and remove the shock absorber and spring assembly.
8. NOTE: If the individual spring and/or shock components are not being serviced, continue with Step 11.
NOTE: For reference during assembly, index the upper mount, spring and shock absorber.
Using a suitable spring compressor, compress the spring until the tension is released from the shock absorber.
9. NOTE: Use the hex holding feature to prevent the shock rod from turning while removing the nut.
While holding the shock rod, remove the nut and the shock absorber.
^ Discard the nut.
^ To install, tighten to 56 Nm (41 lb-ft).
10. Remove the upper mount, dust boot and insulator.
11. CAUTION: Do not tighten the lower shock nut until the installation procedure is complete and the weight of the vehicle is resting on the wheel and tire assemblies.
To install, reverse the removal procedure.
