well then what the hell you doing in this section...last i checked all you had was a piece of black burnt steel.


Well, in reality, my car is now an old beat up black 88, just not legally yet.

if you notice...the rear section of the driveshaft (has the end that bolts to the diff connected to it) is slightly cocked....considering that the 7mge is such a powerhouse a beast of a motor the driveshaft failed under such EXTREAM stress....lol

it should be a straight line from center of bearing to center of bearing..

but if you also notice:

my center support bearing looks like pure shit ....so inspect the driveshaft for all its possible flaws.....there are many!

ShaftMasters (misc vendor section) makes an aluminum 2 piece for our cars...you might want to pull that DS out of the trash since they require the front solid end for a core ;)

They also make a nice one piece if you're inclined to go that route.

Be careful with the praise you are giving IJ, because his head is already swelled up to the size of a watermelon! LOL
