Default The Opinionated Angle( My Take on Pinion angle)

This is my take on measuring pinion angle.

Well you are wrong. Been said here many times. Take the driveshaft out of the car and hide it. The pinion in reference to the crank/ transmission shaft centerline is what you want. They need to be paralllel under power. The end.

That is true, the rear end rises under load, not sure what I said wrong. Either way, that is why i said it is my opinion, and works for me.

X1000

As soon as I see someone measuring the driveshaft angle relative to ANYTHING, I know it's going to be bad advice relative to setting pinion angle.

It's pinion angle VS transmission output shaft angle. Transmission output shaft angle is also the same as the engine crankshaft/front damper angle.

Period, end of story. No way easier to show/understand why then to watch this video.

Always give the same answer. Take the shaft and hide it until done. THE BEST ADVISE that I got when building my own tube chassis.

Yep. That video is wrong. All that is being measured is the rear operating angle. The operating angle is not the same as what is commonly called pinion angle. Leave the driveshaft out of it unless you want to make sure you don't have excessive operating angle like one might find in a lifted truck.

Unless you're driving a lifted vehicle driveshaft working angle is doesn't matter.

And NEVER run brake lines in the driveshaft tunnel.

Another incorrect example of pinion angle. The one thing done right was having the car on boxes. He did get the pinion yoke in the right position also.
I'm just glad I didn't have to watch the previous 30 episodes.

You can measure/set the pinion angle with just the rear end in the air. As long as the suspension of the car, primarily the rear end, is close to the "normal" loaded position, the pinion angle won't change significantly.

The driveshaft on that car is probably at the same angle as the crank shaft .

I got my truck set up like that . My driveshaft and crank shaft are within .5 degree .

Indeed that is the correct way to measure pinion angle. McAnnis is measuring operating angle technically.

All. I Can say is google it. Race craft, smith race craft Jeffers chassis, Bickel chassis, and the hurndreds of other pro chassis builders are all wrong. And 3 guys on a furom are right. Lol. Never know thuo lmfao. Temp you are right,that's way we set it in the first place.
