;)you sure your mother in law wasnt in the boot!!! i sometimes have this problem,every time my missus gets her out the noise goes away!!!on a serious note might be alot less drama to fit a good second hand one which im sure you could source off this forum at a resonable price!!!theres 2 ways to do it,change the center,which you need to remove the axles,if they come out easy alls good ,if they dont tempers could flare,or just change the whole diff,drum to drum,then you will need to bleed the brakes and mess around with hand brake cables,to me the second method is less hassle,i have a ute diff here going cheap,but maybe Ken or someone can enlighten us on different ratios,i think ute,van,ratios are different to sedans,wagons
