I thought you had a stick. Aren't the drive shafts a little different?

I took my driveshaft measurement from the middle of the rear driveshaft section, only because there was some kind of sticker on the end. I don't think there was much difference in angle anywhere on the driveshaft and there shouldn't be.

Just so everyone knows what we're talking about I took a picture of what i'm calling the pinion yoke and the black line shows the place I measure the angle(centered on the bottom of course).

Well I've been to four shops ,and no one carrys a magnetic angle finder? Did those of you that have one have any difficulty or did you order it online?

Hey Andy, Are you measuring the angles with the car level or do you have the back jacked up under the rear axle and the front on the ground?

I first did my measurements with the front and back as level as possible and just today I jacked up just the back under the pumpkin and figured i'd check it again. Of course the angles will change, but the difference shoud remain the same. My pinion yoke measured 6 and my driveshaft measure 3.5, both numbers were on the right side of zero, here's what it looks like



Lots of sites say to measure the pinion angle with the vehicle as level as possible, but the difference between your angles remains the same so it's really not necessary. Placing a negative or positive on the two angles really makes it confusing, especially when you start subtracting. In any event, so long as your pinion yoke and drive shaft meet in a V then the angle will be negative, if they are a straight line the angle is obviously zero and if the meet in an inverted V (^) the pinion angle is positive. So my advice to anyone else is to count the degrees between the two angles and use the above to determine wether it's positive or negative. In my example above the angles looked like this on the angle finder 6-5-4-3-2-1-0-1-2-3-4-5-6, that number scale being the angle finder, both angles were to the right of zero when measured from the same side of the car, so they have 2.5 degrees between them and we know it's a negative pinion angle because of all the crap I said above.

All this will probably just confuse more people.[sm=dontgetit.gif]

Hardware store, should be with the levels. I got mine from Lowes. What shops are you going to? Autoparts stores?

Be sure to read the angle straight even with zero, if you try to read it even at a slight angle you won't get an accurate measurement.

I just got off the phone before checking this forum and Lowes has em ! Plan on jacking the car up-->lowering it and attempting to read with car then lowered. Might have to use my digital camera to get a close up pic.

yeah, lowes, as much as i hate them sometimes, carries the angle finders. im going to jack it back up today, and see. do you get a hard sound when you shift at wide open throttle? i noticed on the highway and accelerating normal, sounds like a regular car, with a bit more noise from bumps. but under WOT at the track, i noticed it "slammed" into gear and the rear end was a lot louder. dont know if this is just do to the spherical ends on the LCAs, or if its a bad angle. but hey, she works. thats most important. i suppose if it breaks, i can put the stocks back on and limp to the dealership...

Just picked mine up at Lowes. I currently don't have any knocking under hard acceleration.

Looking for suggestion on where to take measurements with the aluminium drive shaft.

One measurement taken from flat part of the flange.

This one taken from driveshaft. Let me know what you think for both measurements.

Thanks

No hard sound at WOT shifts and I just got back from the track today. I think almost any angle will work with normal driving, but WOT requires the driveshaft and pinion yoke be as straight as possible so you really have to determine the pinion angle by the type of suspension. the less your rearend rotates upwards at WOT the less negative angle you need to have.
