If the diff on a E90 start grinding, can it be fixed or do you need to replace it?

As far as i am aware its is a sealed unit and cant be repaired, though i could be wrong here.....perhaps someone would care to add ???

Perhaps a reconditioned unit would be the way to go as grinding could mean constant gear damage.

A transmission guy I met while I was on holliday once told me "Anything mechanical can be repaired , even if it is sealed, you break the seal , repair and reseal"

If its the diff , its good to get it open and have a look at the condition of the gears , internals etc and work from there . Might just be the bearings that are gone .

If I only can find a guy in CPT area to open up and check.

Maybe check the condition of the oil first?

Shouldn't be difficult to open it up once its off the car.

Unbolt the cover , if you find metal pieces then that's bad news , But once its open its easy to check its condition .

I agree with zippy320, take the cover off, these are usually easily accessible, check for metal shavings / chippings.

I still maintain that a reconditioned unit will be a cost effective solution, which will save you time on the repair. Unless you can find one at a scrap yard.

I am planning a trip the Cape in December, if you're really stuck, perhaps someone like Gizmo can find a good unit for you and I can bring it down.

But you have to open that diff :sorry:
