So I have this nice clunking noise when I come to a stop/coast below 10mph. I grabbed the driveshaft and felt and saw the play in the u-joint closest to the tranny. I went to AA to buy u-joints and all 6-8 of them were specified 4wd. Does the 2wd use the same u-joints as the 4wd? This is an '88 2wd BA10 Eliminator.
