Hot Rods Steering column question

Slowing the line to do something irrelevant, multiplied across an entire model run, costs a ton of money.

 

Yup, follow the manufactorers instructions. It there ever was an issue with steering that resulted in some bad shit, the maunfactorer would tell you to get lost if their part was improperly installed. I too was a mechanical engineer and designed a lot of power transmitting equipment from minut horsepower applications using 2 u -joints up to turbo shaft jet engines making many thousands of HP. ALL of our drive shafts had the joints in phase. If we did not do this the customer would not accept the design.

The steering on my car is 3 1/2 turns lock to lock. That would be 1 3/4 turn from center, for those of you slow on math today. I don't believe I will be turning it fast enough, or long enough, to feel any out of phase from the 3 u joints in my steering shaft.

Now, I suppose if I were sitting on the fender watching the column in one of those few moments I may be required to turn from lock to lock as fast as I can, I might not like to see what the steering shaft is doing. In all reality, I'd probably be more horrified because of the reason I would have needed to put the column through that awful experience, and I probably wouldn't want to be sitting on the fender during that experience..

Now, the drive shaft in my car is an entirely different matter. At 70 mph, that sucker is really spinning. I want everything right on it. Gene

 

Add my vote for phasing of steering joints!
I worked on a model a hot rod for my employer..
This thing has been thru every shop and expert in the area for over a decade.
It had this weird spot where it would get just a little more difficult to turn .. barely noticable..
What got my attention was once it got past that spot..it would dive to whatever direction you were turning !
Tore it apart , phased both joints..
Problem solved..
Drove like a dream...

Having them in phase certainly isn't going to hurt anything

 

Apples to doughnuts.

 

It won't, and neither will having them not.

My work is in literally hundreds-of-thousands of vehicles now. You would have heard of the recall by now, if I were wrong here.

 

I’m not sure what others are basing their arguments on here....as already said phasing is for vibration. Does not make a bit of difference in the steering Shaft

You are correct about the steering part of this equation, how
however , best to do as the maunfactorer says to do it, common sense. Do what ever you want, this is a free country, at least for the moment.

This stuff doesn’t phase me

 

You have 3 legs. Now you switched one leg for another. Now you turn the other direction.

11. Note: Whenever two joints are used on a shaft the joints must be phased. In other words, the forks of the yokes closest to each other should be in line (in phase), if not binding or premature wear may result.

 

Nope

 

Well, a content director wrote it, so it must be gospel truth.

I'm out. I am done talking to people who won't listen.

I am going to go sit on my pile of money, that I earned, as an Automotive Engineer.

This just like the 010 myth, that just won't die.

 

Watch the video again. Note that the demonstrable effect is at a very slow RPM. Now imagine traversing a windy mountain road and wanting the steering to be equally progressive as you crank the wheel through the turns. An out of phase steering shaft will have the effect of a steering box that has a different ratio at different positions on the steering wheel. Depending on box ratio it could be more or less. It may not bother some people but it would probably bother me.

 

Another way to imagine the feel would be to mount your steering wheel slightly off center.

 

I suppose the phasing on which they focus so much is mainly to play it safe because there will always be the guy that will build his steering with crazy angles and if not in phase will bind.
Now OEM don't care about premature ware if at 500k miles instead of 700k miles. If they save 30sec on the assembly of a car when they assemble 500k cars that represent a lot of $.

 

Finally, someone gets it.

 

Gimpy is right, the phase issue comes into play when the angle is too much and you wind up with steering flop. Sometimes if you phase the joints it will correct the problem if the angle is not too much. I always phase them so when my Hobby members are at the local car show some know it all doesn't tell them it is phased wrong.

 

Getting DD shafted joints out of phase is a bit tough unless the joint manufacturer F's up.
