the 760 joint,wished i'd had known about these b4 last month,i destroyed the yoke on the inner shaft on passenger side actually split the yoke in two, u- joint was all there minus the caps for the inner shaft on the outer shaft and the splines were twisted on the outer,so were replaced with the chrom ones.woulda thought the u-joint was the weak link or even the after market external hubs,impressed with these hubs so far.the left side outer shaft looked like it was cut with a laser ,such a smooth break in the middle of the splines.well we'll see
