问：我的2015年Tahoe骑车真的非常粗糙。您认为它骑得很粗糙吗？

您好，有很多事情可能导致车辆骑行粗糙，例如磨损的悬架组件或悬架组件，这些悬架组件或悬架组件不当调整，磨损的控制臂衬套或磨损的球接头。球接头的设计旨在透过多个平面。当然，由于球接头不断以不同的角度旋转，因此比衬套更快地磨损。承重的球接头支撑车辆的重量，同时为转向系统提供铰链点。负载球接头旨在通过将自己居中插入插座来取消正常磨损的效果。另一方面，非负载的球关节在转向或悬架系统中保持精确的尺寸公差。穿着非负载的球关节磨损会导致前悬架的弯腰，脚轮或脚趾角的明显变化。因此，预先加载了非负载的关节以补偿磨损。磨损的常见症状ball jointsare clunking noises, excessive vibration, steering wander and squeaking.

Control arm bushings are an important part of vehicle suspension systems. Bushings are made of rubber which separates the faces of two objects while allowing a certain amount of movement. As a car moves over tough or bumpy surfaces, this movement allows the suspension parts to move easily. The rubber which is flexible in nature helps to minimize transmission of noise and small vibrations through to the chassis of the vehicle. Bushings are pressed into the control arms at each end of the device to secure the connection to the chassis. The control arm is the device that connects suspension system to the chassis of the vehicle. Control arm bushing is used to hold the bolt in place that connects the control arm to the chassis. They are located at the broad end of the control arm to which the part pivots. These can be replaced separately from the control arms. I would suggest having an expert from YourMechanic come to your location to take a look at your vehicle.
