E30 325iT 3:91 differential.
Moderator: martauto
If anyone has an E30 325iT 3:91 differential available I would like to know please. There was an 'advisory' on the last MOT test and the next MOT is due shortly.

Many thanks, Mart. That was really helpful. Yes, the tester said exactly that. So I take it you are saying that the diff structure is sufficiently robust for this not to be a problem?

they are serious heavy hunks of metal - it would take 2 lifetimes of abuse to even start to do any damage to the case- remove one and you will see what i mean.
It its a bit tatty remove from the car it and give it a good clean and overhual and a good coat of Hammerite and it will be fine for the next 30 plus years.
That MOT tester is clearly not used to working on proper cars.

No probs mate, that`s why we are here , to help each other and................we do not like jokers who are either trying to pull the wool over some ones eyes or they are simply inept.
We do know better when it comes to a forum which is specific to a particular marque.

It's not unheard of for diffs to rust through - despite being about 8mm thick! I've had three over the years that have holed after bead blasting. Much lighter though!
However, the diff does form part of the suspension (subframe has two mounts plus the diff bush) so technically a damaged backplate, bush or casing can compromise the integrity but I think we've just got a case of "arse covering" from someone who doesn't have much experience!
