[QUOTEthe big reason they are "cheap" is that manufactured housing is abundant.][/QUOTE]
Good grief....really?
The manufactured home industry needed axles to move their product. They spec'ed an axle to do the job. They knew the axle's expected duty cycle/longevity/repairability/etc. requirements were all different than the conventional "service type" axles available. They knew there were dollars to be saved, so a spec was developed so an axle could be built to "do the job"....and no more. It would be just as ridiculous to make a statement that the mobile home itself is "just as good" as a built-on-site custom home....it's just cheaper because they're more readily available.
So then do as I've suggested in every mobile home axle thread....ask the manufacturer that builds them what the importance is. I'm guessing that a precision ground spindle is like any other precision machined component. Fitment is superior and the components are more uniform. Completely remove emotion from the decision-making process. The same company makes two parts. One is precision machined, the other is not. Which one is "better"? What makes it "better"?
Discussions about whether or not individuals "need" this quality of axle versus that quality of axle may be valid. But like I've said several times before, individuals starting threads like this are often doing so because they're wondering what axle they should choose. I think it's prudent to enter into a trailer project with good information and your eyes wide open. There's plenty of good information out there from axle manufacturers themselves, and if anyone cares to browse some other forums....it's also not hard to find posts from people that have used MH axles but say if they had it to do all over again....they wouldn't.
What I find to be really ridiculous, are the lengths people go to to convert a MH axle to something else. "I got the axle for free, then swapped out the hubs/drums", or "I converted mine to a serviceable brake by torching off the backing plates and welding some tabs on".
Price a service-type axle and compare that cost to the time/labor you'll spend making a cheap or free axle into something it isn't before making a decision. Then factor in the 14.5 tire thing. There are some *good* 14.5s out there now...as people keep saying. But think about that for a minute. If quality 14.5s are sort of a "new thing", then what was the 14.5 situation before the introduction of these "good ones"? Does that not imply that 14.5s up until then were kind of a limited-use, throw-away thing? Why would a tire manufacturer even make a limited-use, lower-quality throw-away tire?
Same reason a manufacturer would make a limited-use, throw-away axle. It was spec'ed, designed, and built...to do a job for a price.
Last but not least, if MH axle proponents are sooooo convinced those axles are worthy, you'd think they'd be completely on board with with folks like me posting what I've posted. For every potential MH axle customer that does some research and decides to NOT use them, well....that's just a couple more cheap or free MH axles for the fans to snap up 'cause they're such a "good deal".

I have read Dexter's warning about MH axles and frankly don't understand the importance of precision ground spindles
