Well this time it was the CV. (car broke at midnight i couldn't look at the damage, all the noise was coming from the rear so figured the diff blew again.)
The bolts that hold the cv to the hub sheared off!! everything looks intact, all i have to do is find some bolts. i doubt all 6 broke, i suspect that a few of them must have rattled loose.
i am still going to have the sipders welded though.
i dont know, i want 3.08 gears. the 3.54's are way too steep.
