When your Peterbilt 357 or 378 starts to wander on the road, feel loose in the wheel, or show uneven tire wear, your steering system may be due for attention. Heavy hauls, rough pavement, and long miles wear down critical components over time — and that affects safety and handling. Replacing worn parts restores precise steering, better control, and a smoother ride mile after mile.
