If signs of wear such as leaking fluid, loss of damping capability, or issues like sagging or cracked coil springs are observed in the front suspension shock absorber and coil springs, disassembly and necessary overhaul are recommended. The shock absorbers themselves cannot be serviced and should be replaced if found faulty, while the springs and related components can be individually replaced. To maintain balanced characteristics on both sides of the vehicle, it's advisable to replace components on both sides simultaneously. After removing the assembly from the vehicle, ensure it's free from external dirt without damaging the protective spring coating. Utilize coil spring compressor tools to fully engage and compress the spring until tension is relieved from the upper mount. Carefully hold the shock absorber piston rod with a wrench and unscrew the nut, avoiding the use of an impact wrench. Subsequently, remove the upper mount, spring, boot, bump stop, and lower spring seat. If a new spring is to be installed, release the original spring from the compressor; otherwise, it can remain in compression. Examine all components for wear or damage, replacing them as necessary. Check the shock for fluid leakage, inspect the piston rod for pitting, and assess the shock body for damage. Test the shock's operation by moving the piston through various strokes, ensuring smooth and continuous resistance; any signs of wear, damage, or uneven resistance necessitate replacement. To reassemble, install the lower spring seat, bump stop, and dust boot onto the shock absorber, followed by the spring and upper mount/upper seat, aligning the arrow or notch appropriately. With the spring compressed, install the rod nut, ensuring the ends of the spring fit into the recessed portion of the seats and maintaining the specified gap. Tighten the nut to the prescribed torque while keeping the position at both ends consistent. Finally, release the spring tension and reinstall the spring assembly in the vehicle.

Have the front end alignment checked, and if necessary, adjusted.

For 2010 and earlier models, the removal steps include removing the brake caliper, brake disc, brake cable bracket, stabilizer bar link, and wheel speed sensor. On all-wheel drive models, the inner and outer drive axle/hub nuts need to be removed and the drive axle needs to be separated from the hub and bearing using a drive hub remover.
