The frame or frame of a car serves as the base itself on which the rest of the vehicle is built. A frame essentially consists of two main rails, which run the full length of a vehicle and are linked by a series of cross members at varying intervals.
While the exact design of a vehicle’s frame often varies from one particular make and model to another, they all serve the same purpose. from himto a vehicle body to powertrain componentsthey are all fixed to this central frame at a particular point within your construction.
The body of a vehicle is mounted to the frame below, via special body mounts. So much the engine and transmission of a vehicle are held in position by brackets supported by the frame. Essentially, without a well-designed framework, a vehicle simply wouldn’t exist.
Vehicle frames are also carefully designed to incorporate specific angles, ultimately influencing features such as driveline camber and front-end geometry. The slightest variation in these angles can present a number of driving-related problems.
What is considered frame damage?
Any damage that extends to a vehicle’s main supporting structure or compromises a vehicle’s structural damage is classified as frame damage.
The most common example of this form of damage is that which results in a bent frame. This occurs when a blow sustained during a collision is significant enough to distort the main supporting structure of a vehicle.
Damage to any mounting point that is permanently riveted or welded to a vehicle’s frame can also be classified as frame damage. This includes damage that extends to a vehicle’s upper suspension mounts or cross member mounting flanges.
4 point at the box indicating that the box is damaged
Before buying a used car you should check carefully, there are several signs that indicate damage to the frame that you should not ignore.
1.- Non-uniform curves in the frame
In most cases, if a bend in the frame does not match that of the crossmember on the opposite side of the vehicle, frame damage should be suspected.
Most of the bends manufactured in the frame rails are identical from one side of the vehicle to the next, they are identical and extremely uniform in appearance.
2.- Drastically altered alignment
The front end of a vehicle can become misaligned for a number of reasons. However, drastic misalignment, which is highly visible to the naked eye, is often an indication of frame damage. Don’t be fooled into believing a dealer’s claims that the vehicle in question will be fine after a quick alignment.
3.- Suspension components placed in an unnatural way
If a quick look inside a vehicle’s wheel well reveals a shock or strut that’s tilted at an unnatural angle, not matching the opposite end of the same axle, avoid buying that car.
Unnaturally positioned or misaligned shocks or struts serve as an indicator that substantial frame damage has altered the location of a vehicle’s suspension mounting points.
4.- Poorly adjusted components
If several of a vehicle’s body panels and accompanying components appear to exhibit a poor level of fit and finish, there’s a good chance substantial frame damage is to blame. Even a door that doesn’t close properly can sometimes be an indication that more serious problems are at hand.
