Differential mount thread pitch??
 
I am just wondering what the thread pitch for the front diff mount studs is, and also the rear diff mount studs?

I believe it is M12.
I have tried an M12 "coarse thread", but that didn't seem to work.

edit: is it M12x1.25?
the only other ones are M12x1.5 and M12x1.75, and i am pretty sure both those are too big.

ok, so i looked a little closer and the rear diff mount studs look to be M12 x 1.0, which i didn't even think existed??
i'm not going to find that size in store...damn.
well i hope the dealership can get me this stuff fast.

so:
front differential mount studs - M12 x 1.25
rear differential mount studs - M12 x 1.0

i THINK those are the thread pitches...anyone know for sure?

wow, i feel stupid. i've been looking at the wrong thread pitches. no clue why.

i am pretty sure now this is how it is:

front differential mount studs - M12 x 1.50 (same as lug nuts)
rear differential mount studs - M12 x 1.25

i finally learned how to measure thread pitch with a Vernier caliper. hope this info is helpful to someone in the future....

I was really pissed off last week when I found this out the hard way. Fucken why couldn't they use the same thread pitch for all the mounts.

"Pretty sure" or "sure"?

The point is, I want confirmation on the thread/pitch.

yeah, my last post i figured out the thread pitch my measuring with a caliper. today i actually went out and bought the nuts and confirmed. so YES, what i posted in my previous post is correct ("sure").
