Frame Hanger Problems
The leaf spring hanger secures the leaf spring to the RV frame, playing a crucial role in suspension support. Unfortunately, these hangers can suffer from improper welding, rust, cracks, or even break loose from the frame. Many manufacturers do not reinforce the hangers or I-beams, which often leads to hanger failures.

Slide Out Bracket Frame Weld Failure
It’s important to be aware that welds on your slide-out mounting brackets can fail for various reasons. Rough roads, hard braking or acceleration, speed bumps, potholes, lack of maintenance, improper timing of slide-out rails, gear pack failures, rusted frames, and other factors can all contribute to potential problems.




We perform comprehensive frame inspections on RVs to identify and address weak points, ensuring your safety on the road. Our expert team conducts everything from visual checks to detailed tear-down assessments tailored to each unit.
Please note that every RV frame is unique, so we cannot provide a fixed price for inspections or repairs upfront. All inspections, tear-downs, and repairs are billed as straight-time operations. Based on our experience with similar jobs, we will offer a low and high ballpark estimate. Keep in mind that these are rough estimates until we fully assess the condition of your RV.
