Using Diffs as handling aids

[DaveG28]

Was giving my 511 it's first run out today and it was a bit fraught (see the Euro setup thread!). Anyway, having destroyed an outdrive I quickly built a new diff from scratch and dropped it in. Hard to tell for sure but I think it gave me a little push into corners. It was the rear diff I changed and I think I had slightly overtightened the new one, would that have this effect?

If so I'll loosen it a bit (assuming it won't them just undo itself!!)
