Well the bearings went on the 136 amp alternator that I swapped in less than a year ago. I got advance to warranty it and replace it with a 160 amp for a dodge durango. Seems like it will bolt in fine, both are externally regulated. Only difference is the plugs for the field windings. Anyone know which terminal is positive and which is negative in the field windings plug. Alternator is ment for a 2002 dodge durango with the 5.9 but going into a 97 jeep TJ.
