Hey my saph apparently has an xr4x4 lsd diff in it and i need some new drive shafts and wheel bearings on the back as the cv joint on the near side has gone and is knocking like hell. Anyone know where i can get a cheap set as i don't fancy paying £80 each for them i don't know how to tell if its an xr4x4 diff all i know is it has cossie rear suspension set up and discs on the back that's all

any advice and idea of where i can get cheap drive shafts would be greatly appreciated
