Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery before starting work on the suspension system.

2. Inspect and Replace Shock Absorbers

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to gain access to the shock absorber.
3. Unbolt the shock absorber from the upper mount and lower control arm (use a socket set).
4. Remove the old shock absorber and compare it with the new part for compatibility.
5. Install the new shock absorber by reversing the removal steps. Ensure bolts are torqued to the manufacturer's specifications (usually around 60-80 Nm).

3. Inspect and Replace Sway Bar Links

Sub-steps:
1. Locate the sway bar links and inspect them for play or damage.
2. Using a wrench, unbolt the sway bar link from the sway bar and lower control arm.
3. Install new sway bar links and torque to manufacturer specifications (typically around 30-40 Nm).

4. Check Alignment

Sub-steps:
1. After replacing components, take the vehicle to a professional alignment shop.
2. Ensure that the vehicle is aligned according to the manufacturer's specifications.
