For what it's worth.
An example of what I was trying to bring up about quality of a part being sold.
Alot of 'brand name' tool manufactures have moved the majority of their manufacturing to third world countries.
http://www.garagejournal.com/forum/showthread.php?t=2232That thread shows some examples of tool manufactures you used to buy that were made in the usa. Now they have been bought out and/or are now being manufactured elsewhere. It also has a long running debate to the point of manufacture quality and brand name, etc etc..
So, in many cases not only has the manufacturing been shipped out to country's with less stringent labor standards, the quality of the tools themselves have fallen at the cost of the established brand name.
(I'll leave Joes point about safety conditions for employee's out of the picture, for this response but it should be something people are aware of...)
In a global economy many company's are making similar decisions to cut costs. Example?
http://www.goulds.com/ Gould pumps, used to be made completely in the USA (the original foundry is in the town I live in)
One of their engineer’s that we are friends with just got back from China building a huge new facility there. Where all (or most) production of their product is now overseas to china. Their pumps used to be known for reliability, longevity, and availability of parts.
My aunt's well pump just went (a gould pump), and the plumber that replaced it said Goulds pumps now are junk, plastic impellers where metal should be, motors that burn out, hard to get parts etc. So she spent more for a pump that would last longer, have parts available for it, etc.
The point? Well, Goulds had a great brand name at one point. Now, production has been moved overseas and quality of their product cheapened for a better bottom line. Unless you know the history though you would think “Gould pump, good American made pump will last for ever, etc etc.”
So, it's not just related to just car parts, it affects all manufactures.
While I mostly agree that you do get what you pay for. I also think that sometimes if you don’t do research and ‘buy’ based off a product that used to be good. You will end up overpaying for a perceived 'good brand' name which might not keep the same stringent standards that it once did to compete in the global economy.
Another personal example, even though Craftsman tools are made in the USA, I feel their quality has slipped and been lessened over the years to compete with the low cost tool alternatives. I would rather pay more for something (SK, BluePoint, Matco, Snapon) that has a tighter tolerance policy on wrenches which will fit a bolt tighter and break less.
Craftsman have a lifetime warrenty, but when I'm working on a car, if I snap the only wrench I have (even though it's got a replacement) that's time money and energy I need to spend to get it. I would rather pay more to get a tool that will not snap, or not snap as soon (i.e. higher quality.)
So, my point of seeing a point of failure comparison on parts in question will illuminate and eliminate many questions that are raised about the 'quality' of parts and help people make an informed decision about what they wish to spend their money on.
But as with anything these days you need to do some research on what your buying and what the failure rate of said product is.
my 2 cents.
