Re: Z3 3.0i differential unit.

It's tru they are prone to it. You will be disappointed when you spend your money - also not many people[companies] can rebuild these diffs despite what they may tell you and you may end up with a unit worse/with a short life.

Re: Z3 3.0i differential unit.

Why are you attempting to rebuild it? The 3.0 diff will be a Torsen LSD, so very rare in this diff as BMW didn't use this style LSD in anything else AFAIK. So no friction plates in them etc. You can have the bearings changed (but not a quick job as it takes some setting up by a professional to do it...
