Raise the jack slightly to take the spring pressure off the shock absorber lower mount.

To disassemble the strut assembly, follow these steps: Clean the strut from external dirt. Mount the strut in a vise. Install coil spring compressor tools, ensuring they are fully engaged. Compress the spring until all tension is relieved from the upper mount. Hold the strut piston rod with an Allen key and unscrew the thrust bearing retaining nut with a box-end wrench. Withdraw the top mounting, thrust bearing, upper spring seat, spring, boot, and bump stop.

To separate the strut from the steering knuckle, follow these steps: Remove the strut to the knuckle nuts. Knock the bolts out with a hammer and punch. Be cautious not to overextend the inner CV joint. Ensure the steering knuckle doesn't fall outward and strain the brake hose.

Tighten the mounting fasteners to the torque.

When inspecting the strut assembly, check for the following: Strut body for leaking fluid, dents, cracks, or other damage. Coil spring for chips or cracks in the spring coating. Spring seat for cuts, hardness, and general deterioration. If any of these undesirable conditions exist, further inspection or replacement may be necessary.

To test the operation of the strut during inspection, hold it in an upright position and: Move the piston through a full stroke. Move the piston through short strokes of 2 to 4 inches. In both cases, the resistance felt should be smooth and continuous. Jerky or uneven resistance, or visible wear or damage, indicates the need for replacement.
