IRS diff mount wear

[VR38]

If the IRS diff mounts are worn will this increase camber?
I have a standard FE2 suspension but the camber is wearing the tyres uneven.
I jacked the diff center up and it moved over 25mm, is this normal?
Is there any other way to check the mounts for wear?
How hard are they to replace?

it will most likely be the bushes in the IRS trailing arms that are causing this as I had similar issues with mine, would suggust doing the cradle mount bushes at same time too.
I used the whiteline plus ones (black) and they made a huge difference to the car

EDIT: yes easy to replace with minimal tools needed - took me a couple of hours to do both sides

the diff mounts can tear and the diff can drop down in the mount, you will need another diff mount which you can get genuine or from a wrecker, as far as i know no one after market make them, you can also get a diff mount void filler which goes into the genuine mount and makes it more solid and will stop the mount from buggering up again. the diff mount wont affect camber.
