F10 rear diff Bush, particularly weak?

[Andehh]

Just sat with BMW waiting on their response to my rear diff Bush showing a crack across the top rubber joint.

Interestingly, this was already replaced once under their approved used warranty around a year ago.

Car is 2010, 530D m sport with 72k on the clock. I do around 25k miles a year.

Anyone had similar experiences?

[Andehh]

Just to add, spoke to BMW about replacing this one under warranty but they said that the one crack is not enough to justify replacing it. This is a known weak point & due to the number being replaced under warranty BMW have moved the goal posts back. They say one crack isn't an issue, and its only when you get a second split that it can be replaced!

They gave me a price of £420 to replace it in future, if the warranty didnt cover it when I get it checked in a months time (2 weeks before warranty expires)

[Andehh]

Bump, keen to see if anyone else had and anything regarding this!

My Mazda 6 MPS had a weak rear diff bushwhich was a common problem and I ended up getting it replaced with a poly bush. Getting to it was the problem and was a 3-4 hour + job. Not sure if a poly bush once the warranty has expired would be an option or if they are even available?

What was the symptoms of the Bush failing?
