If your vehicle is dropping at one or more suspension struts, it could be an indication of a suspension problem. Here are some steps you can take to diagnose and fix the issue:
Check the air suspension system: If your vehicle has an air suspension system, check the air compressor and the airbags. The air compressor may be faulty, or the airbags may have a leak.
Inspect the shocks and struts: Check the shocks and struts for any signs of damage, such as leaks or cracks. You may need to replace the shocks or struts if they are worn out or damaged.
Check the suspension components: Check the suspension components such as the control arms, sway bar, and tie rods for any signs of damage or wear. These components can also affect the stability of the vehicle.
Check the wheel alignment: A misaligned wheel can also cause the vehicle to drop on one side. Check the wheel alignment and correct it if necessary.
Check the ride height sensor: The ride height sensor measures the distance between the suspension and the ground. If the sensor is faulty, it may not be able to maintain the correct height of the suspension.
Repair or replace faulty components: Based on the findings from the above steps, repair or replace any faulty components that are causing the issue.
If the above steps do not resolve the issue, it is recommended to take your vehicle to a certified mechanic or dealership for further diagnosis and repair. A professional may be able to perform a more thorough inspection of the suspension system and identify any other issues that could be causing the problem.
