What are the sequelae after replacing the subframe?

[AmirRose]

There is no impact after replacing the subframe. The subframe, also known as the auxiliary frame, is a bracket that supports the front and rear axles and suspension. It connects the axles and suspension to the "main frame" and helps isolate vibrations and noise, reducing the direct transmission of sound into the cabin. The main functions of the automotive subframe can be summarized into the following three points: 1. Supporting and fixing function: The automotive subframe typically supports and fixes the engine and transmission. 2. Connection and protection function: The automotive subframe also has a certain connection and protection function. It can increase the body strength by laterally connecting the vehicle body and, to some extent, protect components such as the oil pan and engine from direct collisions. 3. Vibration and noise isolation: The automotive subframe can also isolate the vehicle's vibrations and noise to some extent, preventing them from directly entering the cabin. Most luxury cars and off-road vehicles are equipped with subframes, and some car engines also have subframes installed.
