The driveline in any racecar is exposed to such extreme shock loading that cracked components are a fact of life. It's not a matter of if it will crack, it's a matter of when it's going to crack. At Weddle Industries, our Magnaflux wet bench inspection unit is one of the busiest pieces of equipment in our shop. With it, we have found cracks in places we would have never suspected, periodically resulting in design changes to improve product service life.

The basic theory behind the Magnaflux process was discovered in the 1920's. The simple version of how the process works is this: When a component made of ferrous material is subjected to a magnetic field, there will be high concentrations of magnetic flux around any surface imperfections. These imperfections can be made visible by bathing the component in a solution containing special iron oxide particles, which will glow when exposed to UV light. These iron oxide particles will gather in the high flux areas (areas with surface imperfections) and will glow yellow/green when inspected under a UV lamp. If it is determined that the imperfection is in fact a crack, the part is marked accordingly and set aside for further visual inspection.

Checking driveline components for cracks should be part of any thorough racecar prep, as well as every transaxle service. We check forward gears, ring and pinions, input shafts, shift mechanism, differential components, drive stubs, axles, CV joints, and much more. The wet bench method that we use here is efficient and accurate; we can't imagine doing our service work without it. Our customers rely on our experience and expertise to give them a quality inspection of their driveline components. For pricing and other information, give us a call.
