Why Do the Swivel Wheels of a Trolley Wobble Left and Right?

The reasons and solutions for the left and right wobbling of trolley swivel wheels are as follows: 1. Insufficient tire pressure: Solution: First, check the manufacturer's recommended tire pressure, as the front and rear wheels may have different pressure values. Unequal tire pressure will inevitably cause the trolley to pull to one side. 2. Uneven tread wear: Solution: To optimize tire usage, rotate the tires every 20,000 kilometers to ensure more even wear. 3. Issues with the suspension system design: Solution: Focus on inspecting the braking system, as unequal braking force on the left and right wheels can also cause the trolley to pull to one side.

I've noticed that the wobbling of casters when pushing a car is quite common, and it can be caused by several reasons. Worn-out wheel bearings are the primary culprit—when they age and loosen, the wheels start to sway, making the steering feel particularly unstable, especially during turns. If the suspension system isn't properly maintained, such as damaged shock absorbers or loose wheel hubs, it can also worsen this wobbling sensation. I once experienced this after a long road trip—the car was shaking like it was dancing. Upon inspection, I found it was due to unbalanced tires causing the axle to wobble. Failing to address this promptly can accelerate tire wear and even pose safety risks, so I immediately took it to a professional shop for alignment. Now, I always tap the wheels before heading out to check if they're secure.

The wobbling of the trolley's swivel wheels is mainly due to issues with the wheel components. Common problems include worn bearings or brackets, bent axles, or improper tire installation causing imbalance. These parts naturally wear out over time, and daily use on bumpy roads accelerates the damage. When diagnosing, first shake the wheel to check for looseness. If there's significant play, parts may need replacement. Regular maintenance can prevent issues, such as getting a wheel alignment every six months and keeping the suspension tight. I always remind friends not to overlook such minor problems, as they can gradually turn into major issues, affecting driving safety and leading to costly repairs.

The causes of wobbling universal wheels are diverse, with loose wheel bearings, deformed wheel frames, or unbalanced tires being common culprits. In terms of design, if the wheel axle is not sturdy enough, it will repeatedly shake when encountering rough roads, making it more prone to damage over time. From my experience, it's wise to pay attention to vibrations while driving. If the wobbling becomes too severe, pull over to inspect the axle or suspension components to prevent future breakdowns. Prevention is better than cure, and simple maintenance can avoid these issues.
