Well I was grinding on a drive shaft bolt(long story) grinder ending up going into my pinky. So after I get the bandages and the P.P.E. on that I should of had on, I start to grind again, not noticing that Im grinding through the yoke side of the front diff. So I get all that loose and pull the front drive shaft out then the spline on the t-case disintegrates to a hundred pieces......
