Are there alignment marks between the axle tube and the trailing arm mounts?

The other day after a rather brisk start the driveshaft began to wobble badly. The noise was a loud hammering as the driveshaft was striking the center bearing mount. After removing the driveshafts I found a stiff rear U-joint and a nearly failed center bearing. Also the top torque arm bolt was broken and the differential had rotated so the torque arm holes are about an inch out of alignment. I'm hoping that once the bolt is drilled out I can loosen the trailing arm saddles and rotate the axle until the torque arm holes back into position. Does anyone have some thoughts on this?


Thank you to those who replied with a vacuum leak I had. The procedure in FAQ for the double acting servo was great. (The no cutting one).
