My F28 shattered the diff and blew it through the box in several places running phase 2 in a Corsa. It had been rebuilt/re conned no more than 500 miles before I got my hands on it. It lasted a fortnight. In 3 cars I have destroyed 12 diffs. They dont like my driving style.

My V6 Vectra is surviving so far but has developed a very light CV type noise, hoping its not another diff.
