im fully rebuilding my yb at present and i'm also changing my little ends as they are obivously knackered with the amount of play thats in them. They were making a light knocking noise at idle when cold, a noise which i originaly put down to piston slap as the 2wd are common for this as having a central gudgen pin...but when i stripped it down I found it had already been fitted with the offset pined pistons as found in the 4x4. Further investigatino revealed shot little ends....a item thats cheap to replace when your engine is already in bits.....and as said above should have been changed as a matter of coarse really if a full rebuild was already being done imo
