Default Broken Parts

I am a senior at WMU studying Aviation Flight Science and Maintenance Technology. I am currently in a class called non destructive testing where we used liquid penetrant, magnetic particle, eddy current, and ultrasound to test various parts for cracks, surface flaws, subsurface flaws, etc. One of our projects is to setup a test using parts we bring in and try to find a flaw. I am looking for broken or stressed parts from 4x4s, atvs, dirt bikes etc such as axle shafts, crankshafts, camshafts, connecting rods, ring and pinion gears, or something along those lines that you wouldn't mind donating or loaning to me so I can test it in class. If you have a part that you think might be bad I can test it for you and return it once I am done. I am located in Battle Creek so looking for something close to there. Thanks.

Here are some pics of the mag particle inspection:





And here are some from a liquid penetrant inspection:

How long you need them for? I have a set of dana 60 axle shafts that have been thoroughly beat on but are in one piece. Be neat to have them looked at. You can borrow them but i need them back by about the second week of April

Thanks to @974x4Taco for loaning me a set of dana 60 knuckles. Here are the pics of the testing. Using the mag particle inspection, I found that one of his knuckles has a sub-surface crack and there were some light stress cracks around one of the studs on the back of the knuckle. Here are all of the pictures of the testing. All of the fluorescent spots are non-relevant indications from pits on the surface in the rust. As a thank you I sand blasted the knuckles once I was done with them.

Liquid Penetrant Right Knuckle









Liquid Penetrant Left Knuckle











Magnetic Particle Right Knuckle





Here you can see some light stress cracks around the stud.


Another view of the cracks.






Magnetic Particle Left Knuckle



In this picture you can see where the crack is. It is below the missing stud and travels upward. Where the line is really bright towards the top is the edge of some surface rust so it is a non-relevant indication.


Here is a close up of the crack.

Friend of mine does this, he works for Acuren.

He has nuclear certs, gets to x-ray welds at nuke plants.

Mostly, they inspect welds at refineries.

I have an OEM Suzuki Lt250R Quadracer con rod you can check. It's been used and I'd like to see if I can use it in a motor i'm building or if it's junk.

Thanks for the offer but I already got the project done with the knuckles.
