Yes, there is a bolt underneat the u-joint. Be sure to put the two halves back togetehr in the same position that they came out in, and put the yolk that unbolts back togheter in the same position that it came aprat in.

Good U-joints are only $10....i would replace it while it is out, no matter how good it looks

Thanks!! I will probably replace it. The alignment thing causes a concern. My chilton says the driveshafts aren't supposed to line up perfectly, it says there is a 4 spline, towards the driverside twist with the 2nd saft. Mine appears to be lined up straight the whole way right now. Should I make the change, or leave it like it is? I don't have any shakes or shimmies or vibrations right now. What do you think? Maybe someone could post pictures of "Good" Stock type driveshafts. Thanks

Leave it exactly the way it is. If you get the allignment off 1 tooth, it will vibrate. Just mark everything, put it back together and you should be fine. The shafts are balanced as a assembly, so if you rotate 1 part of the assembly without roating the rest, it will throw it out of wack (i learned that from exeperience

)

Good luck
