Reference Point for C2 diff angle?
Still have a vibration that really becomes noticeable above 50, and it seems to be worse under load. I'm wanting to measure the relative angles of the engine vs the differential to be sure those are within norms.
Is the rear spring clamping plate a reliable place to measure the differential angle?
Thanks

Engine shows about 3.5 degree inclination which seems to be normal from what I've read on this forum. Just want to find a good reference point for the differential.

I just can't picture how it could change unless something is bent or broken. is the snubber bushing on the front of the rear end case is good shape? the bolt tight? that is the only way it can move from my understanding.

I'll be under the car next week and will check those items.

Here is what I've discovered on my car as far as easily checking driveline angles:
I experimented with my angle finder to see if the output yoke angle could be matched up with any of the lower surfaces of the transmission case. I tried across the tailhousing to main case joint and it was pretty close. I found that the front part of the main case sump matched exactly what I got on the output yoke, using a socket on the u-joint and my angle finder on that. This probably needs to be checked on some other cars to verify but it appears that anyone with an angle finder can probably check their driveline angles in about 2 minutes once they are under the car.
1. Check angle on front sump of transmission to represent the yoke angle.
2. Check angle anywhere along bottom of driveshaft.
3. Check angle of differential on the rib on the bottom of the differential case near the pinion snubber.
Very quick and easy.
Here is a recent thread where a lot of this was thrashed about.
