Hi fellas... Your invaluable advise seems to have worked !!!!! Bad juddering/knocking on the back wheel seems to have gone.. New LSD fluid, wheel bearing adjusted and tight !! Oil pressure sensor changed but light still on( it was the one by oil filter that's been changed, and the original seemed to have an 'extention bolt ' on Which has been put on new sensor.. Fuel filter also changed!! Now feels like different motor!! Had its 1st night out shooting and didn't even have to use 4x4 !! Just went up hill and down vale no probs.. But still looking for a mk 4 front bumper!! If I can't find a second hand one any ideas on how much from main dealer??? . Cheers rob
