⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the engine to cool before performing any repairs.
•Ensure the vehicle is on a flat surface and properly supported by jack stands before working underneath.

Symptoms

•Shaking or vibrating felt through the steering wheel and/or seat
•Increased vibration at certain speeds
•Noise accompanying the vibration (e.g., clunking or grinding sounds)
•Pulling to one side while accelerating
•Potential check engine light illumination

Diagnostic Steps

1
Inspect tires for uneven wear or damage; check tire pressure.
2
Perform a visual inspection of the driveshaft and CV joints for any damage or wear.
3
Check engine and transmission mounts for signs of wear or damage.
4
Scan the vehicle's computer system for any error codes using an OBD-II scanner.
5
Test drive the vehicle to replicate the shaking and determine the speed range at which it occurs.
6
Inspect brake components for binding or uneven wear.

Solution
