To remove the cowl cover, loosen the strut upper mounting nuts without removing them. Then, loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the wheel and detach the wheel speed sensor harness from the strut body. Mark the position of the knuckle to the strut by scribing or drawing a line on the steering knuckle following the line of the strut. Detach the stabilizer bar link from the strut and support the steering knuckle with a floor jack. Unscrew the nuts securing the strut to the steering knuckle and tap the bolts out with a hammer. Lower the knuckle using the floor jack to allow room to remove the strut assembly, being careful not to overextend the inner CV joint. Remove the top nuts and pull out the strut. For inspection, check the shock body for leaking fluid, dents, cracks, and other damage. Check the coil spring for chips or cracks in the spring coating and inspect the spring seat for cuts, hardness, and deterioration. If any undesirable conditions exist, proceed to the shock absorber/coil spring disassembly procedure. Guide the assembly up into the fender well and insert the upper mounting studs through the holes in the body. Install the nuts to prevent the strut from falling back through, but do not tighten them yet. Use a jack to position the steering knuckle and install the two lower mounting bolts and nuts. Align the strut with the mark on the knuckle and tighten the nuts to the specified torque. Tighten the top nuts to the proper torque and reconnect the stabilizer bar link to the strut. Reconnect the wheel speed sensor harness to the strut. Install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque. Finally, have the front end alignment checked and adjusted if necessary.

For worn or damaged components, such as the steering linkage and suspension, tire wear may become excessive and stiff, poor riding quality, less fuel economy, and compromised vehicle handling are among the effects. To check the struts and the shock absorbers you should: park the vehicle on a level surface; switch off the engine; put on parking brakes. Push down at each corner of the vehicle several times to determine if it stops moving and returns to a level position within one or two bounces. A continuous movement or failure to return to its original position may indicate that shock absorbers are worn out or weak. Repeat this check at each corner of the vehicle. Raise the vehicle to inspect for signs of fluid leakage or damage in both struts and shocks. Ensure that they are securely mounted and undamaged; replace them as a set if necessary. Visually inspect steering and suspension components for any damage, distortion, oil leaks or worn seals, boots, bushings. Check for movement at steering knuckle-to-control arm ball joint by examining control arm bushings. If there is any movement here you should replace the balljoint. Finally push and pull on front tires to look for play in steering system components; inspect tie-rod ends for looseness or wear.

Lower the knuckle using the floor jack, being careful not to overextend the inner CV joint. Then remove the top nuts and pull out the strut.

Remove the lower nut and bolt of the shock absorber.

It is important to replace components on both sides of the vehicle simultaneously to maintain balanced characteristics.

Clean away external dirt without damaging the protective coating on the spring, and use coil spring compressor tools to compress the spring and relieve tension from the upper mount.

Raise the lower control arm with a floor jack.

Push and pull on the front tires and inspect the tie-rod ends for looseness or wear.
