What are the symptoms of a bad ball joint in a truck?

[DiLucille]

Symptoms of a bad ball joint in a truck are as follows: 1. When the front wheel ball joint is faulty, the following symptoms may appear: rattling noise on bumpy roads; unstable vehicle, swaying from side to side; brake pulling to one side; steering failure. 2. Excessive play in the ball joint: It is prone to breakage under impact loads. Repair it as soon as possible to avoid danger. Relevant information is as follows: 1. Introduction: The outer ball joint refers to the tie rod end ball joint, while the inner ball joint refers to the steering gear tie rod ball joint. The outer and inner ball joints are not connected together but both need to function. The steering gear ball joint is connected to the steering knuckle, and the tie rod end ball joint is connected to the parallel rod. 2. Function: The ball joint in a vehicle uses a spherical connection to transmit power between different axes, providing multi-angle rotation, allowing the steering mechanism to turn smoothly, reducing vibration, and achieving smooth steering. The ball joint, also known as a universal joint, refers to the mechanical structure that uses a spherical connection to transmit power between different axes.
