How to Set & Measure Pinion & Driveshaft Angle

[@mattt83]

Was waiting for you to say, make the noise!

Great video. Thank you so much for the explanation about how the rear diff is actually pointing UP when the measurement device measures it as being down. That was kicking my butt and no one could explain that to me.

[@bradmccracken8304]

So many people say just set the diff pinion down 3 degrees 🤦‍♂️. Thank you for clearly explaining what’s actually involved 👍

[@Brendan.Wheatley]

Thanks for another great tech video, they are quite informative!

[@runslikeapenguin]

Huge help, measuring from my crank pulley was messing up my numbers

[@nicholasash9389]

If it's an IRS like on a VE Commodore you can set it all on the hoist. With the IRS, the angle wont change when the car is off the ground. Excellent video Broomy

Great explanations and information Broomy... Cheers !

Nice vid mate very informative.

I installed a 3" lit kit in a 78 J10 Jeep. Now as it sits with truck frame is maybe 1 degree "Rear end up", I find results these measured numbers here below. Trans output end is 4 degree down. Driveline is 2 degree down. Diff Yoke is 11 degree Up. What would be the correct shim angle to correct for this. The Yoke at 11 degree from a Post kit results is quite extreme IMO. thx

What about left to right from pinion to tailhousing on transmission. On an offset such as an 8.8 from an Explorer has. Does this matter a whole lot?

[@mikeymasi]

onya Broomy plenty of helpful info in this

[@zundappwatercooler]

Who made that tailshaft loop🙈

[@NUT84G]

appreciate the video, explains how to use the app properly and the slope angles, cheers mate

Off topic question: What's the HP rating on that GJ driveshaft Broomy?

[@BroomysGarage]

It’s a 3.5” unit so from memory was around 1400hp

[@MafiaboysWorld]

@@BroomysGarage Thanks bro. 👍

[@shawnwimberly9294]

Right on

note to editor, insert link at 3:35 for previous video ;)

Rather then cutting the crossmember mount, you can space it from the body with longer bolts and an alloy or steel spacer...

[@BroomysGarage]

You could do that also 100%. I chose not to here because it would have meant having to remake all the dump valve hoses, and remake the rear section of the belly pan.

[@bluedog373]

Way over complicating a simple process. Engine should almost always bet set at a down angle. Pinion should be pointing up at same angle. I.E. 3 dgrees down, 3 degrees up. For drag racing all bets are off. Depends on chassis and rear axle mounting. No need for calculators.

[@Headsup9550]

You CANNOT check driveline angles on a lift. Suspension must be ride height with suspension loaded. Total waste of time!

[@BroomysGarage]

Maybe watch the entire video next time champion. The car is sitting on wooden blocks when making the measurements at the end of the video.
