If serious damage has occurred or a large number of parts need to be completely replaced, then such work should be entrusted to a professional. If the damage was due to a collision, the shape of the body must also be restored. In accordance with the principles of design, the shape and loading of the vehicle can be affected by damage to its individual parts. In such cases, it is necessary to contact a specialist who will give an opinion on the need to replace parts. If the shape of the body is not restored, this will lead to the fact that, firstly, the car will not be controlled correctly, and secondly, unequal loads on the suspension, transmission and steering will lead to uneven wear or complete failure. Tire wear can also become excessive.
