Just been sorting my rear axle with a new UJ, owe my car an apology it was the flange not the half shaft which was worn. As to Freelander type being fatter I put a micrometer on the cups I removed and checked it against the new UJ's. Two Freelander type, larger rollers metal protection for the seal and spider marked GKN 5J, from different source's and a third UJ marked GKN 6E, smaller rollers no protection for the seal, all the same size. The old spider was not marked so make unknown, tried a cup from each of the three new UJ's in the worn flange, just as loose as the one I removed so it is scrap.
Regards
Paul
