Question

What must be performed on a truck suspension system to adjust torque rod length and drive axle alignment?

a) Adjust the nuts on the U-bolts
b) Add additional spring wedges
c) Remove or add washers (shims)
d) Adjust the position of the spring hangers

Answer 1

To adjust the length of a torque rod and the alignment of a drive axle in a truck suspension system, one should remove or add washers (shims).

Step-by-step explanation:

To adjust torque rod length and drive axle alignment on a truck suspension system, the correct action to be performed is to remove or add washers (shims).

Adjusting torque rod length is crucial for maintaining proper axle alignment, which is essential for the safe operation of the vehicle. Improper alignment can lead to uneven tire wear, poor handling, and other safety issues. The adjustment process typically involves loosening the fixation bolts of the torque rod, adding or removing shims to achieve the correct length, and then re-tightening the bolts securely.

Adjusting U-bolts, adding spring wedges, or repositioning spring hangers might be performed for other types of suspension system adjustments, but they don't directly adjust the length of a torque rod.
