I've been trying for a couple of hours

to get the lower bolt out that hold the alternator to the alternator bracket ('95 2.5L w/ATX). I've tried all kinds of combinations of 3/8" and 1/2" extensions, u-joints, adapters, etc. to get on that 13mm bolt head. Do I have to remove the axle shaft?
What worked for you??????? Thanks in advance. . . .
