Extreme Drops

heavey metal that Justin Drove 2300 miles each way from Ventura, CA to Indianapolis, IN

Ok, I knew what vehicle you were talking about.

many don't though so i threw up a few pics

That is so cool you knew that but we figured to show all people that do not know.You can drive a full blown show truck across country .

Yeah, I'm surprised this thread isn't a lot more active than it is.

It would be cool to see some "action" shots of Heavy Metal out on the Interstate! I think I remember hearing it even rained on you guys.

I remember seeing it in indy looked like a swiming pool and justin didnt care LOL interior was replaced i think 2-3 times due to un foreseen rain storms

This should explain it.

Actually, that only explains the equal but opposite need for the cancellation of the angles to eliminate the possibility of vibrations (it also states the d.shaft should be sloping down approx 1°).

My buddy also questioned how the d.shaft knows whether it's sloping up or down thus it shouldn't make a difference.

This is why I stated earlier that the 'difference' would be that when the shaft slopes upward to the pinion, you calculate the angles differently. The result is typically excessive angles that are nearly impossible to cancel thus why I feel they recommend it to be avoided.

Hey Scoti how far from Dallas to Columbus....y'all only have about six months!

17hrs straight through..... been there & done it so I know what to expect. This truck will make that drive.

Quoted from that source:

When the slopes are in the Same direction on two connected components, Subtract the smaller number from the larger to find the u-joint operating angle. When the slopes are in the Opposite direction on two connected components, Add the measurements to find the u-joint operating angle.

This would mean if the trans is angled down & the d.shaft slopes up, you would add the angles to arrive @ the working angle of the joint. We'll say the trans is @ 3°dn & the shaft is 2° up: 3+2 = 5° working angle.

If the driveshaft is sloping down from the pinion & the pinion is angled down, you would subtract the angles. We'll say the d.shaft is @ that same 2° up & the pinion is 3°dn: 3-2 = 1° working angle.

The numbers yield a 4° difference.

ken, do you have any side shots of that truck so that the wheels can be better seen?

Lets see what I have...

Quoted from the source:
Always measure the slope of the drivetrain going from front to rear. A component slopes downward if it is lower at the rear than the front. A component slopes upward when it is higher at the rear than it is in front.

Wouldn't this phrase mean that a gearbox with it's tail shaft lower then the converter shaft would mean it slopes down(which makes sense) but the rear end which you would think if the input shaft was angled up then it would be sloped upward but the phrase says it would instead slope downward!

I would have to sit and draw this out in CAD but I am on my way out the door to do some snowmobiling for the weekend!

Yes it was built it in 90 days and took it to detroit then drove it to
Gm in detroit in the freezing ass cold weather.lol
