After all the reading I've done about pinion angles, I'm still confused. Some say to subtract the two numbers and some say to add them. Anyway, I checked my OEM driveshaft and it's at -6 (sloping down). My pinion was initially at 0 but I adjusted it to +3 (sloping up).

-6 + (+3)= -3

Is this correct?

Thanks in advance!

it will vibrate if its not correct

I've read that site many times and I'm still a bit confused. The driveshaft doesn't vibrate right now. I'm just confused about whether the pinion should be angled down more or up more. The driveshaft is angled down at 6 degrees or -6. The pinion was at 0 initially. If I subtract -6 from 0 then it would be -6 which is too much. I then adjusted the pinion to point up so that would make it +3. Pointing up is a positive number isn't it? That's how I came up with this number...
-6 + (+3) = -3

The Cherod site says to subtract the two numbers. If my DS is at 6 then what should I set my pinion to? 3 up or 3 down? Do you still subtract no matter if the pinion is pointing up or down? Somehow this is where I'm confused. Like I said, my pinion is now pointing up beyond horizontal by 3 degrees.

pointing down is basically want you want for the pinion. so that would be negative a couple degrees then

I guess I read the angle gauge incorrectly when measuring the pinion and thought that pointing the pinion up would give me the correct setting. I'm going to point it down for a reading of -3. Thanks!
