Mine has just blown, want to keep it Defender instead of Disco due to 200tdi. Have a LT77 recon'd gearbox on. In the Manchester area, need some help because I've also blown either the rear diff of one of the half shafts....all during a Trafford centre run!

When you say blown do you mean not driving or in bits?
You can find all the bits to re man the box if the casing is ok, I priced up the bits and compared the prices, island 4x4 have an OEM bearing kit which has quality parts and works out a bit cheaper than individual bearings.
