Occasionally and rarely vehicle frames can run into issues – some of these issues include; bent frame members, loose frame members, cracked or broken frame members, and rust jacked fame members.
Every frame member (Frame rails, cross members, fasteners) is integral to the vehicle and was designed and engineered in a very specific way. When these components fail they can cause issues from weakened structural areas, excess frame flex, poor handling, misalignment, all of which could make for unsafe driving conditions.
Oftentimes these failures are repairable, however, some of the repairs can be very extensive and as a result expensive and time-consuming. These failures or deteriorating conditions are sometimes not noticeable while driving but can lead to a major failure. One of the best ways to catch these failures is regular inspection of your unit, often when the unit is having an oil change as an example.
quite often some of the more major failures that happen with frames, while repairable, are often not cost-effective. This lends even more to the idea of regular inspection and preventative maintenance.
