Difflock Failure survey RESULTS

Posted: Wed Aug 27, 2003 6:37 pm

Please keep in mind the disparity of results reported (eg 1 locker reported with 1 failure = 100% failure ratio).

The primary focus of this survey was to highlight the most common problem with differing designs of locking diffs. A locker failure is equated to a failure of the locking mechanism due to it's own system's malfunction (eg Detroit runs out of oil or ARB air line breaks).

Please excuse the bodgey format. If you would like it in sexy Excel please PM/email me.

Thanks to all who particpated :)
