Trying to get all the angles right. Starting with Engine,Trans down angle if car is level. What is the range from good to bad and ideal?
My Dart has Super Stock springs, would the 2* down at the trans and 1.5 * up at the pinion still apply? Or does anyone have the same set up that might know their Trans, Driveshaft and Pinion angles?2 down and 1.5 up with full tank of gas for measure.
Thank you, that's kind of what I thought, never hurts to ask! Thanks all for your input. RonThe angles are right but every car is different so you need to measure yours and then enter the figures in the Spicer calculator and adjust if necessary.
The engine/trans and the rear axle need to operate in the same plane. This will mean the universals operating angle is the same at each end of the driveshaft.
Knowing someone else's angles will not help you.
ThanksI have a digital angle finder with a bubble on it that I find really handy.
One thing you need to get right is are the angles rising or falling with regards to the front to rear of the vehicle. You need to double check your measurements or you get all screwed up.
Once you get your head around this the calculator makes the rest easy.
Yeah, It's confusing, I've been reading, watching video and seems like what they're saying is that the angles need to be parallel. But super stock springs need to be down at the front yoke 3*to 5* to work. Figuring that on a hard pull the angle comes up to parallel. I think it's one of those deals that it's either a race car or a cruiser.There is a ton of confusion with driveline vibrations and angles. Even the calculators can be confusing. Some say the driveshaft angle does not come into play. Only the transmission angle and pinion angle but I have found that to not always be true. Basically, if you have shudder under load and goes away when you let up, your pinion needs to go down. If it gets worse when you let up, the pinion needs to be raised. In my case, the calculations showed everything was good but I still had some vibration. I swapped in a pair of Hotchkis shackles with 4" spacing in place of the 3.5" raising the rear up just 1/2" and my vibration went away.
