its a twin wheel one, 1993.. the diff cover comes off, so you unbolt the diff and pull it out from the rear.. i put all the bits in, adjusted as best i could then took it upto kevin at the gearbox centre, in caister near great yarmouth, he set it all up properly..
i had to replace mine as it had been noisy for years, then it decided to break a few teeth off...
it runs nice and quiet now.. still i wish i'd bought the tube axle as you just swap it over, fit your brakes and half shafts job done.. much easier than fitting a diff.. job for the experts really, getting the crushable washer and backlash etc right is a nightmare..
