Jack car and support as per your last post.
Exhaust can stay, 6 female hex bolts on each hub, undo compress the drive shaft towards the diff and swing away from the hub... Then pull out of diff. Undo the driveshaft flange and then finally diff supported, undo the two rear mount and the front one and lower away.
Refit is the reverse. An hours work with your pit.
Today's top tip, drain the diff first...
And don't forget to refill the new one
Point to note... the six hex bolts that connect the drive shafts to the hubs are "stretch bolts" and, in theory, should be used only once. .. so 12 needed
I've no idea if the re-use of the bolts when I changed the diff was the cause of my problems with a drive shaft coming loose last year, but I would not wish that on anyone if it happened at speed - I was lucky it happened at less than walking pace but still wrecked the drive shaft.
"Pulling out" the drive shafts was not as easy as it sounds .. I had to get a tyre lever in behind the ABS Reductor wheel and very carefully prise the shaft outwards to overcome the spring clip thingy, once it started to move then it pulled out OK.
There was a "small" problem with the diff bolts, the ones needed for the replacement were different to the ones I took off with the old diff. Shackeng took us all around little places in swidnod until we found some that worked !!
The diff , even when empty, is reasonably heavy and cannot be supported one handed ... don't ask me how I know ..
(don't have the luxury of a pit so mine was done on axle stands with very limited space .... you can probably guess what happened .....
)
Fitting the replacement with the help of RobG and Shackeng was far easier and less painful ....
