How Do You Adjust the Airbag Suspension on a Semi Truck?

Adjusting the airbag suspension on a semi truck is an important task that should be carried out regularly to ensure the truck runs smoothly and safely. The process of adjusting the airbag suspension involves checking the vehicle’s ride height, replacing worn or damaged airbags, and making necessary adjustments to ensure the truck is properly balanced.

The first step in adjusting the airbag suspension on a semi truck is to check the ride height. This can be done by parking the truck on level ground, then measuring from the ground to the bottom edge of each side of the frame rails. If there is an imbalance in ride height between each side, then it is likely that there is an issue with one or more of the airbags and they need to be replaced or adjusted.

Once any worn or damaged airbags have been replaced, it’s time to make any adjustments necessary for proper balance. This can be done by adjusting inflation pressure on each individual airbag, as well as adjusting their height if necessary. It’s important to remember that too much inflation pressure can cause excessive wear and tear on other components of the suspension system, so it’s best to err on the side of caution when making adjustments.

Finally, after all adjustments have been made and verified by a second person, it’s important to take a test drive in order to make sure everything feels right. If any issues are noticed during this final test drive, then further adjustment may need to be made until everything feels perfect.

Conclusion:

Adjusting an airbag suspension on a semi truck requires careful attention and expertise. It involves checking ride height, replacing worn or damaged airbags, and making necessary adjustments for proper balance. After all adjustments have been made and verified by a second person, it’s important to take a test drive in order to ensure everything feels right before getting back out on the road.
