Rear diff

Morning all, whilst driving my freelander home last night I found part of the drive like I was driving with a flat tyre, stopped had a look around and found there was a lot of oil coming from the diff. The only problem prior to this was she was making a Sally bearing like nose on full lock around bends.any ideas what this may be and the cost of fixing it? Think if its too much I may just scrap it.

just change the diff but check the ird and vcu as it might be the vcu that has coursed the diff to go also the diffs are all the same LR only list one for all models

So the petrol ones are the Same as the derv? What would you expect to pay for changing the diff

are your front tyres bigger in diameter than your rears?
