Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, pry bar, jack stands
Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels for easier access to suspension components.
3. Inspect control arms and bushings for any signs of deterioration or damage.
4. If damaged, remove the old control arm by loosening the bolts and using a pry bar if necessary.
5. Install the new control arm, ensuring it is properly aligned. Torque the bolts to the manufacturer’s specifications (usually around 70-80 Nm, but verify for the specific part).
6. Repeat for any other worn suspension parts identified during inspection.

3. Check and Repair Steering Components

Tools Required: Socket set, torque wrench, steering wheel puller (if applicable)
Sub-steps:
1. Inspect tie rod ends for wear. Check for play by wiggling them with your hands.
2. If worn, loosen the locking nut and remove the tie rod end from the steering knuckle.
3. Install the new tie rod end, ensuring it is properly seated, and torque the nut to manufacturer specifications (usually around 50-60 Nm).
4. Reassemble any components removed during inspection and ensure everything is secure.

4. Alignment

Tools Required: Alignment rack (best performed by a professional)
Sub-steps:
1. After replacing worn components, take the vehicle for a professional alignment.
2. Adjust camber, toe, and caster angles according to manufacturer specifications.
