What is the last step when replacing a spring pack?

The last step when replacing a spring pack involves loading the springs and then re-torquing the U-bolts. This step is critical because it ensures that the spring pack is under the correct load and that all components are properly seated and secured before the vehicle is put back into service. Re-torquing the U-bolts after loading allows for any slight adjustments that may be necessary as the springs settle under weight, ensuring that the suspension system remains stable and functions effectively.

Loading the springs appropriately ensures that they take on the weight of the vehicle and operate as intended. If this step is skipped or improperly done, it could lead to compromised suspension performance or even failure, resulting in unsafe driving conditions. Thus, this process is vital for safety and for the longevity of the suspension system.
