i don't think the pin is in the axle , ( unless u mean the cotter pin at the end )there is a roll pin at the transmission connection , that almost cannot be there , it may be in the axle , in which case the mechanic didn't get the axle all the way "home" before reinstalling the roll pin - i could see that happening . sloppy work by the guy with tools who worked on your car ( can't really call him a mechanic ) . good luck , hope thats all it is , get the pin out , get the axle back in place , all the way home , install the pin . keep on rock-in' ! later:headbang:
