Pinion angle w/driveshaft in.

-
Don't know of any way. You have to remove the shaft to get an accurate trans (drive train angle). You also need to remove the shaft to get a good pinion angle. The angle of the shaft (itself) isn't as important as the trans and pinion angle. The shaft is only held in there by 4 small bolts.

Can you use the U joint caps as a reference? Such as a large socket fits up against the cap.
 
My U joint on the transaxle has caps and snap rings. The snap ring is flat enough to take a measurement. This is not the definite way to do it but with the drive shaft in may work enough to tell you what you have.
 
You can use a socket the right size against the u-joint cap on both the transmission slip yoke and the pinion yoke. Just hold it tight against the bottom of the cap and make sure that the yoke is oriented so that it is level side to side.
 
I have always used front of the balancer or oil pan rail to get trans angle. For the rear end, remove the pinion snubber plate and get angle from the pad on top.
 
Tremec has a downloadable angle finder for I phone that uses the phone as a level and uses the installed angle of the driveline as part of the equation.
Then it tells you which of the three angles is off and by how much.
 
The Tremec app sounds interesting, I will have to get it. Thanks
 
I just downloaded it, its hiding in the site, only took a couple minutes to find it. Looks like it will work nicely.
 
Reason being is I'm 70 and will have to do this by myself. Jacking the rig up, removing shaft. Lowering rig. Crawl under, take measurements. Jack rig back up, reinstall shaft, then lower rig again. My 72 Swinger is pretty low. Needless to say, I'm a lazy old fart.
 
4 good axle stands will take care of part of the process. Im only 53 and can see your point. Thats why i bought a drive on hoist.

Love to have a drive on hoist. My single car garage, is quite narrow. None, that I looked at, would fit in there.

24x32 for me,i cut the rafters and put in collar ties, a big box of sorts. Lift any vehicle without issue, other than the door needs to be closed.
Its tight, especially for engine swaps.

How would I read the angles of transmission and pinion with the driveshaft still in? Really don't want to drop the shaft.
Thanks

If you have a smartphone there's a app from TREMEC that has you hold the phone on the driveshaft and yokes and determines all your angles the says if its ok or not. it walks you through it and takes out the guess work, sorry,, I should have read the other posts about this. you guys beat me to it.
