Dry powder mag is pretty much the standard on ferrous, "liquid mag" will catch 
finer cracks.
For non-ferrous, dye penetrant/developer or "zyglo", which is dye check with a 
black light.
All methods require clean parts and a set of good eyeballs.
The cracks are out there, we just gotta find them in time...

Mag inspection is always better than penetrant.  Penetrant requires the cracks 
be open to the surface, mag doesn?t.  The only reason to use penetrant over mag 
is when the material you are checking is not ferromagnetic.

Interesting- I?ve had bad luck with the dye Pegasus sells- mangaflux shows 
cracks it didn?t.

Great, I got one set of Canley and they rest are stockers and I just bought a 
dye penetrant set that allows me to do it at home. I got enough Magnaflux brand 
dyes and developers in a kit to last me years at about 100.00 bucks on e bay. 
You might want to check it out as it?s more sensitive from what I know as 
compared to magnufluxing a part.

Sure- still have both failed pieces.  Fortunately they did not totally fail in 
action!

Any chance you?d take some pics of the actual failed part with some dots or 
arrows where you are seeing the cracks for us so we know better where to look 
for them??

I?ve been using the trunnionless front suspension vertical link on my GT6 that 
Canley Classics sells for the past two years.  I?ve now had two fail the annual 
magnaflux tests.  They cracked in different locations, one right at the 
machining line for the flat for the stub axle nut, on the back side where the 
steering arm passes through, and one on the upright at what appeared to be a 
casting mark, near the bump you see in the photo below.  Neither crack was 
visible to the eye. The upright Canley sells no longer looks exactly like the 
photo - it now has a machined area on the back side, away from the wheel, much 
like stock ones.  Maybe I just had bad luck, but between two cracks and some 
binding issues at the ball joint I had to rectify, I would no longer recommend 
these.

 

I started using the Canley units when the stock ones developed cracks in the 
traditional place at the top end of the threads where the trunnion is.

 

I have now installed uprights I got from Jigsaw Racing 
https://jigsawracingservices.com - Mark Field, in England.  The main difference 
from stock is they are not drilled for a grease fitting or grease boring down 
into the trunnion, which should make them stronger where the stock ones usually 
fail.  Mark races Spitfires and GT6s for himself and for customers in vintage 
racing and claims he has never had a failure.  He further claims that the units 
are made in the original forging molds and by the same people that made the 
Stanpart units.

 

Main point is, even though it?s a pain, pull your critical parts off and get 
them magnafluxed at least once in a while.  I?ve become paranoid and this is 
now an annual exercise.  The machine shop I go to usually does it for free 
while I am watching, probably because I?m usually dropping off engine parts 
where the real dollars get spent!
