A broken frame rail on any vehicle is dangerous. A broken frame rail on a truck that hauls 80,000+ lbs. is extremely dangerous. Normally a visual inspection is the only way to determine if your frame is broken. Recently we had a 2006 Peterbilt 379 transfer come in with a broken frame rail. A really broken frame rail.
The driver noticed that his usually some-what rough riding rig was driving uncharacteristically smooth. At the same time the steering was all over the place and it was harder to control. Then he noticed his hood wouldn't close all the way on the passenger side. After a walk-around inspection he noticed a major crack in his frame.
Once the driver saw the seriousness of the crack, they bound the frame with chains and blocks. This got the truck to our shop with out further damaging the truck. If the frame were to crack all the way, the truck would not be moveable.
The mechanic marked the placement of all components, took measurements of the inside of the frame channel then began to disassemble the frame rails. Once the rails were disassembled the crack was welded up.

Driving any commercial vehicle with a broken frame is illegal.
A lifted 2008 Ford E-350 4WD 6.0 van left our shop today with a new custom exhaust. The customer requested we install a 4" stainless steel Magnaflow exhaust. A Magnaflow muffler kit for an F-250 was modified to fit the E-350. This is a 24" muffler, the length was chosen to mellow the exhaust noise.
We installed V-band clamps on either side of the test pipe and modified the down pipe.
Another job completed and a happy customer!
