⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is secure on jack stands before performing alignment adjustments.
•Always disconnect the battery before working on electrical systems related to the drivetrain.

Symptoms

•Vehicle pulls to one side during acceleration
•Uneven tire wear
•Steering wheel vibration or misalignment
•Increased noise from the affected side
•Vehicle drifts during coasting without acceleration

Diagnostic Steps

1
Inspect tire pressure on all four tires to ensure they are inflated to the manufacturer's specifications.
2
Check for uneven tire wear patterns, which may indicate alignment or suspension issues.
3
Perform a visual inspection of the suspension components on both sides for damage or wear.
4
Test drive the vehicle to confirm pulling direction and assess if it changes with acceleration or braking.
5
Use a wheel alignment tool to verify alignment settings against manufacturer specifications.
6
Inspect the drivetrain components, including CV joints and axles, for damage or wear.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Use jack stands to elevate the vehicle safely.

2. Tire Inspection and Rotation

Sub-steps:
1. Remove all four wheels using a lug wrench.
2. Inspect each tire for uneven wear and damage.
3. Rotate the tires if necessary to promote even wear.
Tools Required: Lug wrench, tire pressure gauge.

3. Alignment Adjustment

Sub-steps:
1. Use a wheel alignment tool to measure current alignment angles.
2. Adjust the toe, camber, and caster as per manufacturer specifications.
3. Tighten all adjustment bolts to the specified torque values.
Tools Required: Wheel alignment tool, torque wrench.
Safety Warnings: Ensure the vehicle is secure on jack stands before performing alignment adjustments.

4. Suspension Component Replacement (if needed)

Sub-steps:
1. If any suspension components are damaged, remove the affected part (e.g., control arms, tie rods).
2. Install new components, ensuring all bolts are torqued to manufacturer specifications.
3. Recheck alignment after replacing any suspension parts.
Tools Required: Socket set, torque wrench.

5. Drivetrain Inspection and Repair (if necessary)

Sub-steps:
