Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always secure the vehicle with jack stands before working underneath.
•Allow brakes to cool before handling to avoid burns.

Symptoms

•Vibration felt through the steering wheel during acceleration
•Shaking of the vehicle body when braking
•Increased noise from the drivetrain or brakes
•Potential pulling to one side during acceleration or braking
•Uneven tire wear observed

Diagnostic Steps

1
Inspect tire condition and pressure for uneven wear or low pressure.
2
Check wheel alignment to determine if misalignment is causing vibrations.
3
Examine the brake components for wear, including pads, rotors, and calipers.
4
Perform a visual inspection of the driveshaft and CV joints for damage or wear.
5
Scan for any error codes using an OBD-II scanner to identify electronic issues.
6
Test drive the vehicle to replicate and assess the severity of the shaking.
